How Fine To Grind Coffee? (Solution found)

What Coffee Grind is best for drip coffee?

  • A drip coffee grind is a medium grind or commonly known in many coffee houses as a #6 grind. A Cone Filter Drip is a #5, and produces a bit stronger tasting coffee since it takes a little bit longer for the water to run through the coffee. Chemex Coffee is one of the more popular types of coffee pour-overs.


How thin should I grind my coffee?

Recommended grind size is between medium and fine, depending on steep time. Siphon brewers use pressure to force water into a chamber holding the coffee grounds. Once the steep has finished, heat is removed, which creates a vacuum in the lower chamber and pulls the water through a filter.

Can you grind coffee too fine?

Grinds too fine can settle and pack together in the basket of the espresso machine, clogging an otherwise even mesh and stymieing water’s journey through. As a result, some cups end up bitter, while others end up sour; a few taste strong, a few taste weak.

What is the normal grind for coffee?

Medium: A medium grind setting is what many coffee shops will use for a regular cup of drip coffee. Its consistency is very similar to sea salt. Medium Fine: The medium fine grind size is a happy medium between the sizes needed for drip coffee and espresso. Most people will use this size for a pour over coffee.

What happens if you grind coffee too coarse?

In general, if you brew coffee that is ground too coarse, the coffee can be under-extracted (weak), and less flavorful. If your coffee is ground too fine, however, the coffee can be over-extracted and bitter. Extra Fine: Coffee grains still barely discernable. Finer than granular sugar.

Should coffee be ground coarse or fine?

Because the coffee is steeped in boiling water, the contact time between the water and coffee is much longer, which requires a coarser grind. Grinding the coffee too coarse will make the coffee weak. Grinding too fine will make the coffee murky and taste bitter.

Is espresso grind coarse or fine?

For espresso brewing, you need to use a fine grind setting; so the ground particles will be around 1/32 of an inch, or 0.8 mm. Although this exact value can vary with different coffee beans, as well as between different espresso makers.

Does grinding coffee finer make it more bitter?

Your over-extracted, more finely ground coffee will not only taste stronger—it could be bitter-tasting or gritty as well. The more bitter flavors in your coffee especially will turn out more pronounced if the grind on your beans is too fine and the coffee gets over-extracted.

Does grind size affect coffee taste?

If your coffee tastes watery and acidic, you may be grinding your beans too coarsely. If your coffee tastes overly bitter, you may be grinding too finely. A coarser grind may improve your brew. (Brew time and temperature will affect flavor as well.)

Is Starbucks coffee fine ground?

For the freshest tasting coffee, we continue to recommend starting with whole beans and grinding them fresh for each pot. All Starbucks stores can grind coffee to this specification. Espresso machines are grind-sensitive and require a very fine grind, 30-35 seconds in a blade grinder.

How do you measure coffee beans for grinding?

Measure the beans. Place a cup on the scale and rezero the scale so you will be measuring only the weight of the beans. Add a few coffee beans at a time until your scale reads 30 grams (1.1 oz). 30 grams (1.1 oz) will yield about 3 cups of coffee and will make for a universally accepted strength.

Should I grind coffee beans daily?

For those brewing a single cup every morning with a quality burr grinder, emptying a bag of coffee every 10-14 days, it is probably advantageous to continue doing so. You could also ask your barista to grind part of the bag at the shop, brew through that part for 3-4 days, then fresh-grind the rest at home.

What is cowboy coffee?

Cowboy coffee is a traditional drink made by cowboys on the trail. It’s brewed by heating coarse grounds with water and then pouring it into a cup after the grounds have settled. Let’s talk about the rich history of this outlaw drink.

Why am I getting coffee grounds in my coffee?

Paper filters Using too fine a grind and/or too much coffee will cause a build-up of water that overflows into the gap between the paper filter and the filter basket. This causes a real lot of ground of coffee to bypass as there’s absolutely no filtration from the filter basket, resulting in a very muddy cup of coffee.

Ultimate Coffee Grind Size Chart – How Fine Should You Grind?

If you’re just starting started with coffee brewing, you might be feeling a little overwhelmed by the many grind sizes available. The optimal grind for a French press, espresso, or cold brew depends on the style of coffee being made. It is possible that you may be tempted to purchase pre-ground beans rather than learning how to grind your own beans at home. But before, have a look at this! Never fear, you will not be forced to settle for less than optimally roasted coffee beans. We’ve put up a coffee grind size chart that will provide you with all of the information you need to become a pro grinder.

See our commonly asked questions to choose the appropriate grind for your preferred brewing technique.

Why should you grind coffee beans at home?

Freshness reigns supreme when it comes to coffee flavor and aroma. No matter what roast or nation of origin your beans are from, you’ll want to make sure they’re as fresh as possible in order to extract the most flavor out of them. This includes ensuring that they have been roasted and ground as soon as possible before serving. Coffee beans begin to lose their flavor and get stale as soon as they come into contact with air. Consequently, freshly roasted coffee has the optimum flavor between one to two weeks following roasting, however freshly ground coffee loses flavor 15 minutes after grinding due to the oxidation process.

To get the maximum taste out of your beans, grind them right before brewing them.

The specifics will be covered later, but bear in mind that certain brewing techniques demand extremely particular grinds, which may be more difficult to get at your local grocery store or that may not be available in your preferred kind of coffee beans.


  • It has a much better taste. Match the grind size of your coffee beans to the size of your coffee machine. Experiment with different grind sizes to see what works best for you.

7 Types of Coffee Grinds:

Coffee grinds are available in seven different sizes. To learn out what they are, what they look like, and what sorts of brewers they are most suited for, continue reading this article. We’ve taken close-up photographs of each of the seven coffee grind sizes for our thorough list so that you can get a better understanding of the texture you’re looking for. We’ve included an American quarter, which has a diameter of 0.955 inches and a width of 0.069 inches, to give you a sense of size.

1.Extra Coarse Grind

It is common practice to just gently grind very coarse beans, which is accomplished by utilizing the biggest setting on a burr grinder.

They have an extremely rough texture, and the form of the original beans can still be seen in the beans. This grind is best suited for use in cold brew and cowboy-style coffee preparations (coffee boiled in a pan with grounds).

2.Coarse Grind

Extra coarse beans are just lightly ground, generally using the biggest setting on a burr grinder, to get the desired consistency. They have an extremely rough texture, and the form of the original beans may still be seen in the beans themselves. For cold brew and cowboy-style coffee, this grind works best (coffee boiled in a pan with grounds).

3.Medium-Coarse Grind

Medium-coarse beans have a texture similar to that of rough sand, and they are in the middle of the medium and coarse grind levels. This grind is best suited for use in specialist brewers such as the Café Solo or the Chemerex.

4.Medium Grind

When it comes to pre-ground beans, medium grind is the most frequent grind size, and it has a texture similar to smoother sand. This grind is ideal for use in drip coffee machines and siphon brewers alike. In an AeroPress, it will also work if you allow it to brew for more than three minutes.

5.Medium-Fine Grind

Medium-fine beans have a texture that is slightly smoother than sand, but not quite as smooth as sand. Suitable for cone-shaped pour-overs, vacuum brewers, and AeroPress brewers that require two to three minutes of brewing time, this grind is the finest choice.

6.Fine Grind

Finely ground beans have a very smooth texture that is close to powder in consistency. This sort of grind is also readily available in pre-ground bags, where it is commonly referred to as espresso grind. It is vital to crush coffee beans for those who brew espresso. It also works well in an AeroPress, with a brew duration of one to two minutes depending on the model.

7.Extra-Fine Grind

The extra-fine grind size provides a texture that is similar to that of powder or flour. Extra-fine grind is most commonly used to brew Turkish coffee, and it is referred to as a Turkish grind in some circles.

What’s the best grind size for each brewing method?

This image may be used freely as long as a link back to is included for acknowledgment. An excellent rule of thumb to follow when selecting the appropriate grind size for your beans is to remember that, the more coarsely you grind your beans, the more slowly they’ll transfer flavor to the water. If you have a preferred brewing method, you may want to explore how it works. When you swiftly pour water through coffee grounds, the water must be able to pick up flavor as quickly as possible.

  • Because brewing methods such as the French press and cold brew need water to be mixed with the grounds for at least a few minutes, coarsely ground beans are recommended in order to minimize over-extraction. In the center, you’ll find brewers such as pour-overs and drip pots, which let water to rest with the grounds for a few seconds and, as a result, require medium- to medium-fine grinds
  • At the other end of the spectrum, you’ll find espresso machines. A method that pushes water or steam through the grounds very fast, such as espresso machines and Moka pots, is on the other end of the spectrum. These systems require very fine grounds.

Why does grind size matter?

The size of the grind can have an impact on the flavor and texture of your brewed coffee. A difference between wonderful, tasty coffee and tasteless, boring, or too textured coffee can be determined by this factor.


If you’ve ever had a silty, bitter cup of French press coffee, you’re probably aware that choosing the improper grind size can have an impact on the flavor of your brewed beverage. When brewing with a metal filter, such as a French press, percolator, or espresso machine, grinding the beans too finely might cause the grounds to pass through the perforations of the filter, resulting in a coffee that is salty, foggy, and too textured in flavor.

The tighter weave of cloth and paper filters ensures that no grinds will get through, even if you grind very finely. However, you may find that your coffee takes longer to brew when using these filters.


You’ll want to extract as much flavor as possible from your beans in order to achieve the greatest flavor. Extraction is the process through which water flows through coffee grinds, gathering up the specific tastes and caffeine that make coffee unique. If possible, avoid over- and under-extraction during brewing and instead aim to stay in the middle of a desirable extraction range.

What’s under-extraction?

Under-extraction occurs when the water does not take up enough flavor from the coffee grounds as it travels through them. Incorrect filter selection or water temperature can cause this, but the most common cause of under-extraction is coffee grounds that have been ground too coarsely during the extraction process. Unsuccessfully extracted coffee has a weak, flat flavor that is acidic and mildly sour or salty in flavor.

What’s over-extraction?

When the water runs through your grounds and picks up too much flavor, this is referred to as over-extraction. It is most commonly caused by coffee beans that have been ground too finely. Coffee that has been over-extracted is bitter and overpoweringly strong, and it lacks diverse nuances.

Types of Grinders

If you want to get the ideal grind size, an excellent grinder is required. Blade and burr coffee grinders are the two most common types of coffee grinders. Blade grinders use a propeller-like action to chop up coffee beans, which is accomplished by spinning metal blades. When using a blade grinder, you may alter the grind size by grinding for longer or shorter periods of time; the longer you grind, the finer the grind size will be. Blade grinders are less costly, but they are also less exact and generate more inconsistent grinds than traditional grinders.

Best Coffee Grind Size FAQ:

For use in a French press brewer, a coarse grind with a chunky texture akin to sea salt is recommended. Avoid over-extraction or excessive silt in your coffee by following these instructions.

What’s the right grind size for cold brew?

It is recommended that you use an extra coarse grind size for cold brew, which is normally the biggest setting on a burr grinder. This is due to the fact that it is brewed at a low temperature for an extended length of time.

What’s the perfect Chemex grind size?

The Chemex brewer works best with a medium-coarse grind level, which has a texture similar to coarse sand, since it produces the best results.

What’s the ideal AeroPress grind size?

When making AeroPress coffee, you’ll want to use a grind size that’s somewhere between medium and fine, depending on how long you want it to brew.

Use medium-sized grinds for a brew that lasts three minutes or more. Medium-fine grounds should be used for the first two to three minutes. Fine grinds can be used for one to two minutes at a time.

What’s the best grind size for pour-over coffee?

Pour-over coffee brews best when the grind size is between medium and medium-fine.

What’s the most optimal espresso grind size?

Finely ground coffee beans are required for espresso preparation. Because espresso pushes water through beans fast, you’ll want fine grinds if you want to make a powerful shot of espresso.

What’s the perfect drip coffee grind size?

Typically, a medium grind size, akin to smooth sand, is optimal for drip coffee machines to function properly.

Which grind size works best when using a Moka pot?

Moka pots, which are comparable to espresso makers, require a finer grind size than espresso machines.

How often should you grind coffee to keep it fresh?

Every time you brew coffee, ground your coffee beans to ensure the freshest flavor. As soon as you ground coffee, the flavor begins to fade approximately 15 minutes later, so to keep it fresh, grind only the amount of coffee you’ll need shortly before brewing.


It is not necessary to be a technical expert to learn how to grind your beans. With the assistance of this detailed tutorial, you will be able to confidently grind your beans to the exact size you want. There are a variety of grind sizes available, ranging from extremely coarse to extra fine, and grinding your coffee beans correctly will ensure that you make a wonderful cup of coffee every time. We hope that our coffee grind size chart has answered all of your queries and has assisted you in brewing the greatest possible cup of java!

Grind for aFrench Press– Coarse Grind

When brewing coffee in a French Press, it is important to choose a coarse, uniform grind. A coarse ground will appear chunky due to the coarseness of the ground. Because the coffee is soaked in boiling water for an extended period of time, the contact time between the water and the coffee is significantly greater, necessitating a coarser grind. If you grind the coffee too coarsely, the coffee will be very weak. If the coffee is ground too fine, it will become murky and unpleasant in flavor.

Grind for aPour Over– Medium-Coarse Grind

A coarse, uniform grind is required for brewing coffee in a French Press. This is due to the fact that coarse ground will appear chunky. A coarser grind is required because, when the coffee is soaked in boiling water for a longer period of time, more contact time occurs between the water and the coffee bean. If you grind the coffee too coarsely, the coffee will be watery and bland. If the coffee is ground too fine, it will become murky and harsh in appearance and flavour.

Grind for a Siphon Coffee Maker- Medium

When siphoning coffee, a medium grind size is required, between between filter and espresso, but closer to the filter size. Siphon coffee machines, which commonly employ a cloth or metal filter, produce a cup of coffee that is full-bodied and free of sediment. This means that the grinds cannot be too small or they will clog the filter, but neither can they be too large or the filter will clog. Because it is a short brewing procedure, if the grinds are too large, the flavor will be compromised.

Grind for aStovetop Espresso Maker– Fine Grind

For stovetop espresso machines, use a fine coffee grind to get the best results. A fine grind will be equivalent in size and texture to sugar in terms of size and feel. It should also be a little coarser in texture than the grind used in a standard espresso machine. Because of the brief period of time that the coffee ground is in contact with water, a fine grind is necessary. In the espresso maker, pressure builds up, forcing the water through the fine grinds of the coffee beans. Because a coarse grind will prevent the water from extracting the flavor from the beans, you should use a fine grind if possible.

This makes espresso the most delicate of all the coffee kinds when it comes to producing good coffee and the size of the grind of the coffee beans used in brewing it. If the grind is even slightly finer or coarser than desired, it can have a significant impact on the final flavor of the espresso.

Grind for Turkish Coffee Maker- Extra Fine

Traditional Turkish coffee is an extremely strong cup of coffee with fine grinds. That description alone should be enough to convince you that this type of coffee deserves an extremely fine grind. A good comparison is that the coffee grinds should be the size of powdered sugar, which is even finer than the grinds used in an espresso machine. Turkish coffee requires extremely small grinds, to the point that certain grinders are unable to accept it. Consequently, while shopping for a coffee grinder, be certain that it has the appropriate settings if Turkish coffee is your preferred beverage of choice.

Burr Coffee Grinder

A Turkish coffee is simply an extremely strong coffee that has fine grinds. This type of coffee necessitates an especially fine grind, as is obvious from the description provided above. As an example, the coffee grinds should have the consistency of powdered sugar, making them even finer than the grinds used in espresso. Turkish coffee requires extremely tiny grinds, to the point that some grinders are unable to handle it. In order to ensure that your coffee grinder has the necessary settings if you want Turkish coffee, search for one that has the appropriate settings while shopping for one.

The Complete Guide to Coffee Grind Size

One of our aims at Trade is to encourage home brewers to experiment with their own brewing recipes and spend more time exploring new types of coffee that they like drinking. In this lesson, we’ll discuss one of the most crucial and simple to change variables in the brewing method: the grind. For those who want to start at the beginning (or, more accurately, at the beginning of irregularly and inconsistently sized particles), grind size relates to how large or little the individual coffee grounds are.

Typically, instead of using the terms “large” and “little,” we refer to the size of grind particles as “coarse” and “fine,” respectively.

Coffee ground surface area

The physical events that take place on a relatively tiny scale throughout the brewing process have an influence on the grind size. The core of the coffee grind cannot be reached by water while it is attempting to extract flavor particles from a single coffee bean and into your cup by a syphoning action. Starting from the exterior of the coffee particle, it must first wash away any soluble coffee solids that have accumulated. So, let’s assume you have one coffee particle and you cut it in half to see what happens.

The more the number of fragments you divide the coffee particle into, the greater the amount of surface area that will be exposed (while the total mass of coffee stays the same).

As a result, finer coffee grounds will extract more quickly in any brewing technique, but coarser coffee grounds will extract more slowly.

Coffee ground resistance

It is possible that the grind size has a secondary influence in certain brew procedures, particularly those in which water runs vertically, down into and through a bed of coffee. Taking two batches of coffee and grinding one finer than the other, you will notice a difference in the way the coffee particles interlock with one another. As an example, assume you had two tubes, one filled with rocks and the other with sand. Although this analogy is not derived from the real world, it appears to make sense to everyone I’ve ever presented it to.

Although the grains of sand will have extremely little spaces between them, the water will have to travel much further and take much longer to get through.

Because grinding too fine will result in greater extraction, it will also slow down your flow and increase the amount of time you spend on the job altogether (which will also increase extraction).

Grinding coffee at home

Blade coffee grinders and burr coffee grinders are the two major types of coffee grinders available. Blade grinders operate in the same way as a food processor or blender, cutting the coffee into smaller and smaller pieces with rotating blades. More coffee particles come into touch with the blades of the grinder the longer it is in operation, resulting in a lower particle size. In its most basic form, burr grinders are two interlocking discs (they can be flat or conical, but for the sake of this description, they function in a similar way) with sharp teeth made of materials such as ceramic or stainless steel.

  1. Coffee is amorphous, meaning that it does not physically break down into discrete particles.
  2. However, the majority of the coffee you ground will be around the same size: the size of the space between the burrs in your grinder.
  3. What is the significance of uniformity in grind size?
  4. Consider the example of something quite simple: table salt.
  5. While coffee does not have the same flavors as other beverages, it does have flavors such as sourness, sweetness, and bitterness, as well as a variety of aromatic components.
  6. As a result, if your coffee grounds are uneven, you’ll extract too much bitterness from some of the small particles and just acidity from some of the coarse particles, making it difficult to make a consistent, wonderful cup of coffee.

It goes without saying that you should keep track of how large the grind size seems, but you should also keep track of how long you’re grinding for and how much coffee you’re using. Make an effort to be as consistent as possible.

The grind size for every coffee brewing process

Blade coffee grinders and burr coffee grinders are the two major types of coffee grinders. Grinder blades operate in the same way as a food processor or blender, cutting the coffee into increasingly finer bits as the blades revolve. More coffee particles come into touch with the blades of the grinder the longer it is in operation, resulting in smaller coffee particles being produced. For the sake of this explanation, burr grinders are two interlocking discs (they can be flat or conical, but for the purposes of this explanation, they function in a similar way) with sharp teeth made of materials such as ceramic or stainless steel on them.

  1. Coffee is amorphous, meaning that it does not physically break down into discrete particles when brewed or ground.
  2. Most of your coffee, though, will be about the same size as the spacing between the burrs in your grinder.
  3. Why is uniformity in grind size so critical?
  4. Consider something as simple as table salt as an example.
  5. Coffee, on the other hand, contains flavors such as sourness, sweetness, and bitterness, as well as a plethora of diverse aromatic constituents to explore and enjoy.
  6. As a result, if you use uneven coffee grounds, you will extract too much bitterness from some of the small particles and just acidity from some of the coarse particles, making it difficult to make a consistent, wonderful cup of coffee every time.
  7. It goes without saying that you should keep track of how large the grind size seems to be, but you should also keep track of how long you’re grinding for and how much coffee you’re using.
  • When making Turkish coffee, it is important to grind the beans as finely as possible, not only to get the appropriate body of the coffee, but also because the coffee grounds only come into touch with extremely hot water for a brief period of time during the brewing process. Those minute particles are essential for extraction speed
  • Espresso is ground somewhat coarser than coffee, but still very fine. Because of the extremely short brewing period, we require the tiny particles once again. They’re also critical for providing water resistance, which is quite significant. The pressurized water used to brew espresso is extremely high pressure, which increases extraction speed. However, without the fine grind that allows us to push those grinds extremely close together, the pressurized water would simply shoot through the coffee bed too quickly, resulting in an uneven espresso. Pour over and automated dripbrewers are two types of brewers for which we grind in the medium range. Generally speaking, for smaller, single-serve pour overs, we’ll grind the beans a touch finer than usual. Because we’re using less water, it’ll be more difficult to make the brew last longer, therefore the finer grind will aid in extracting the flavor more rapidly. Aside from that, the resistance provided by the finer coffee grounds will aid in making the water flow more slowly. To avoid extracting too much coffee or making it too difficult for the water to pass through, grind the beans closer to medium coarse if you’re brewing a gallon and a half of coffee at once (for example, at a coffee shop). For use in a French press, crush the ingredients rather finely. However, while this is beneficial for extraction (since the water is just sitting there), it is also necessary in part because the filter of the French press would let too many minute particles to get through if the beans were ground finer. a refreshing cup of joe Coffee beans are also ground quite coarsely, both as a result of the longer brewing time and as a result of the filtering, which is not always as fine as the paper filter in a drip machine

Adjusting coffee grind size

While you’ll want to keep your grind size within these basic ranges, most grinders have plenty of wiggle area to accommodate tiny modifications. Those modifications will assist you in brewing coffee that is not only great, but also tailored to your preferences. More acidic coffee is produced when the brown substance in your coffee grinds is extracted into your cup in greater quantities. The greater the proportion, the more bitter the beverage. So if your pour over tastes bitter, coarsen the grind a little further and repeat all of the other procedures.

If your French press is overly acidic and lacks a lot of sweetness, grind the beans a little finer and the flavor should be more balanced.

Understanding this modification, however, is critical in bringing out the rich, chocolatey notes of the Brazilian coffee and the flowery taste of the Ethiopian coffee.

Espresso: The Grind

It is sometimes stated that a goodespressoA little coffee beverage, around 20 mL, produced on an espresso machine using pressured hot water extracted via compressed coffee: is difficult to come by. An espresso working definition can be summarized as follows in its most basic and unadorned form: A little amountMore I’ve heard it said that the grinder is the most critical piece of equipment for creating espresso, and I tend to agree with that. Too many people have costly espresso machines, yet they try to cut corners and get by with a shoddy grinder, which I find unacceptable.

  • Uneven grinding can result in a variety of difficulties, including excessive extraction speed.
  • The taste of roasted, ground coffee is released or “extracted” when hot water is added.
  • It is referred to as channeling when little water jets emerge during the brewing process of espresso owing to unevenly distributed grounds.
  • It is preferable, in my opinion, to invest in a high-quality mill first and then, if required, save money on the espresso machine, rather than the other way around.
  • You will not be able to create excellent espresso with an ablade grinder.
  • The traditional home coffee grinder, which operates on the principle of a high-speed spinning blade.
  • Additionally, a good grinder should prevent clumping of the grinds, keep the beans cold while they are being ground, and aid in the distribution of coffee uniformly throughout the basket.

Using the Correct Grind

When producing espresso, it is critical to have a fine, uniform grind throughout the process. How good is it? Topinchthe grinds between my thumb and fingers is a fast and simple technique that I employ to determine whether something is safe. When you don’t have access to your $3000 set of laboratory screen analysis equipment or your scanning electron microscope, this is a good substitute. (Joke!) When you squeeze the coffee, it should clump together at the middle of the pinch where the pressure is the greatest, but not too much.

If the powder clumps excessively, it is too fine and will result in over-extraction of the liquid.

The middle image is too fine (you can see a thumbprint in it), while the bottom image is too coarse (you can see a finger print in it).

The easiest way to judge your grind is to watch the time it takes for the water to pass through the puck; if it takes too long, grind it a little finer. If it’s moving too slowly, try grinding it a little coarser.

Espresso Grind is Too Coarse:

When producing espresso, it is critical to utilize a fine, uniform grind throughout the whole process. So, how good is it for you? Topinchthe grinds between my thumb and fingers is a fast and simple test that I employ. In situations when you do not have access to your $3000 laboratory screen analysis equipment or your scanning electron microscope, this method will suffice. (Joke!) When you squeeze the coffee, it should clump together at the middle of the pinch where the pressure is the most intense, but not excessively.

The particle size is too fine and will result in over-extraction if the material clumps excessively.

The middle image is too fine (you can see a fingerprint in it), while the bottom image is too coarse (you can see a smudge on the surface).

It may be necessary to use a little coarser grind if it moves too slowly.

Espresso Grind is Too Fine:

While the espresso grind quickly compresses and clings to the finger when squeezed, it expands and creates a dense “pancake,” which clogs the portafilter.

Espresso Grind is in the Right Range:

That’s exactly what I was looking for! To be honest, it’s almost there. Of course, this is not a precise test, but it will provide you with the information you want. The grind cakes and adheres to the finger, but it is not as tightly compressed as the “too fine” picture, which is more densely crushed. The freshness of the roasted beans, as well as the degree to which they have been roasted Roast level refers to how dark a coffee has been roasted and is expressed as a percentage of the total roast level.

Additionally, the way water is absorbed and forced through the puck have an influence on grind, thus these are considerations to consider.

An adjustable grinder with stepless adjustment allows you to make minor modifications to the degree of grind, which may be quite useful.

Things is less a question of getting it “correct” as it is of getting everything to operate in harmony with one another.

Keeping Things Clean!

Any burr grinder will do. A coffee grinder that grinds beans by passing a flow of beans between a pair of revolving metal discs is described here. A coffee grinder that grinds beans by passing a flow of beans between a pair of revolving metal blades is described here. Many grams of coffee will remain in the burrs, chute, and other parts of the machine. Generally speaking, the larger the grinder, the greater the amount of grinds it will keep. Despite the fact that a coffee shop grinds new coffee every minute, this can be a major problem for a home user since the old grinds become stale and have a bad influence on flavor.

In the end, there isn’t much that can be done regarding grind retention; it is just the cost of employing professional equipment in a domestic environment.

We recommend that you clean your burrs at least once a week by passing instant rice or a specific grinder cleaner (such as Grindz) through your machine.

Burrs are graded based on how many pounds they can grind before needing to be replaced — often dozens of pounds for home grinders and hundreds of pounds for commercial machines — consult your grinder’s handbook for specifics on how to determine this.

Burr replacement is typically a straightforward procedure, and replacement burrs are presently available for purchase for $30-$60, depending on the grinder.

Grind Distribution Basics for Espresso

So you’ve invested in a decent grinder, a good cup of coffee, and a fine espresso machine, but your shots aren’t up to par? There’s a strong chance that your distribution isn’t quite right. The term “distribution” refers to how uniformly the grinds are dispersed in the portafilter. This is the section of an espresso machine that contains the filter basket, into which the coffee grinds are inserted. It is the portion of an espresso machine that contains the filter basket, which is where the coffee grinds are deposited.

  • A classic example of poor distribution is a picture that appears to be okay for a few seconds before abruptly gushing out a light-blonde sloppy jumble of light.
  • This indicates that the flavor is not being extracted evenly by the water, and as a result, the finished shot will taste off.
  • Before tamping your coffee, try to focus about distributing the grinds around evenly, making careful to fill any cracks and pushing grinds all the way to the edge of the coffee cup as you level it off.
  • Light roasting for espresso grinding!
  • For those who are genuinely hooked, you might want to consider purchasing a bottomless portafilter (see below).
  • When you use bottomless portafilters, you can see distribution problems and channeling: if the flow is uneven across the bottomMore, where the entire bottom (including the spouts) has been cut off to expose the bottom of the filter basket.
  • The idea behind this is that you can identify particular locations where channeling is taking place.
  • Keep in mind, though, that when channels break through, they frequently discharge water in unexpected locations, so when using a bottomless portafilter, be prepared to clean up the mess!
  • Keep in mind that it is far easier to distribute evenly during dosing than it is to fix improper distribution after the fact.
  • The interspecies hybrid of Coffea Arabica and Coffea Canephora (Robusta) known as Hibrido de Timor (abbreviated HdT) was discovered in Timor Leste in the 1940s.

There are a variety of distribution tactics available, each of which is highly supported by a large number of excellent baristas. Searching for “espresso distribution” on video websites should turn up a plethora of results for those who are interested in learning more.

A Last Resort for Distribution Problems

In the event that, despite all of the above, you continue to receive bullets that suffer from channeling, it may be necessary to employ the so-called “Weiss Distribution Technique,” also known as WDT. The primary concept here is to agitate the grinds in the portafilter to break up clumps and ensure that everything is equally distributed throughout the coffee. Visit the home-barista page on the WDT for a plethora of further information on it.

What is the best way to grind my coffee? What kind of equipment do I require? What Grind Level Do You Want? For the amateur, this sounds like misery, but for the Coffee Nerd, it sounds like bliss. Mostly because it represents yet another measurable method of measuring and yet another opportunity to spend money on yet another gadget. In terms of equipment, you may need to upgrade from the whirly blade grinder you received as part of your last divorce. The amount of money you spend on coffee is determined by the type of coffee you are brewing.

  1. A constant coarse grind is required for the French Press, but you shouldn’t have to spend more than $100 or so for a grinder that will work well for both the French Press and the Drip method of brewing.
  2. The majority of these grinders will also work well for Turkish Coffee or Greek Coffee, which requires the finest grind of all the coffee varieties.
  3. Sure, there are definitely more levels in practice than that, but this will provide you with visual signals that will allow you to feel sure that you are getting near.
  4. To provide some context for those who are not familiar with the coin, it measures 21.21 millimeters in diameter by 1.95 millimeters in thickness.

3 Common Mistakes People Make When Brewing French Press Coffee

We independently choose these items, and if you make a purchase after clicking on one of our links, we may receive a commission. While the French press is not for everyone, it is one of the most traditional techniques of brewing coffee, and when done correctly, it may yield a delicious cup of coffee. Do you want to learn how to make the ideal morning French press? Avoid making these three typical blunders, and you’ll be sure to enjoy the greatest cup of coffee each and every time. The simplicity of a French press is its appeal – simply grind your coffee, add water, and you’re ready to go.

Here are three frequent mistakes people make while brewing French press coffee that you should avoid making yourself.

1. Not grinding the beans properly.

When it comes to producing decent coffee, the grind is extremely crucial — some would even argue that it is the most critical factor. When making French press coffee, you want the beans to be coarsely crushed and evenly distributed, as shown in the photo above. In addition, freshly ground beans are always preferred, so if you haven’t gotten around to purchasing a grinder yet, now is a good time to do it. Useful Hint: When pressing down on the filter, you can tell if the grounds are too fine or too coarse depending on how fine or coarse they are.

If you are able to push the filter down with little resistance, the grounds are likely too coarse to function properly.

2. Using the wrong quantity of coffee.

The art of the French press is in the ratio of coffee to water, and because you’re extracting the coffee, the time is as vital to master. A general rule of thumb for French press coffee is a coffee-to-water ratio in the range of 1:10: that is, 1 gram of coffee for every 10 grams of water. This ratio can vary — some say it should be a bit higher, while others say it should be a little lower — but I’ve found that 1:10 is a decent compromise that is also easy to remember and calculate. Granted, not everyone enjoys the process of measuring out their coffee every time they prepare a pot of coffee.

In the example above, I don’t bring a scale with me when I travel (although I know some people do), but I know that my portable grinder grinds around 40 grams of coffee, and I know how much water I need to fill the French press with in order to obtain approximately 400 grams of water.

It is not the most accurate or reliable approach, but it is effective when there is no scale available.

3. Leaving the coffee in the French press after pressing.

The coffee in the French press will most likely become over-extracted and bitter if left in the press after the brewing process is complete. That’s because even if you’ve pushed the plunger all the way down, the coffee will continue to brew. Considering that you want to enjoy your coffee immediately after making it, the ideal approach is to prepare only the amount of coffee that you will consume (for example, one cup for yourself or two cups if you are with company). Pour the remaining coffee into a thermos or carafe right away if you know you’ll need more than one cup and don’t have time to make another batch for your second round.

Coffee grind size: Why it matters and what you should be using

Taylor Martin is a contributor to CNET. The key to making great coffee at home is to spend a little additional time on a few, straightforward procedures. For example, making sure to use the proper temperature water, weighing coffee instead of measuring by volume, and grinding your own beans on the spot are all simple measures to take. Out of everything you could experience while brewing coffee at home, grinding coffee is perhaps one of the most important processes, as the grind size alone can have a significant impact on the taste of your cup.

Learn how the grind size influences your cup and which grind size is best for your preferred brewing technique.

Why grind size matters

Among the several variables that influence grind size, contact duration, extraction rate, and flow rate are the ones that make the most significant effect. To put it another way:

  • The extraction rate of coffee grounds increases as the surface area of the coffee grounds increases. Grind the coffee more finely in order to maximize surface area. Generally speaking, the faster an extraction rate is, the less contact time is required. It is possible that a finer grind will limit the flow velocity of water, hence extending the contact duration.

As a result, if you are using a brew technique that has a short contact time, the grind should be finer than usual. The contact time in an immersion brewer, which steeps coffee grinds in water for several minutes, is significantly longer than in most other brew techniques, necessitating a coarser grind than in most other brew methods. If the contact time is excessively long or the grind is too fine, the outcome will be an over-extracted brew that can be harsh in flavor. Because of the coarseness of the grind and short contact time, weak coffee will result from using these methods.

Although different types of filters, pressure, and temperature may all influence grind size, most brewing techniques run at temperatures between 195°F and 205°F (90.6°C and 96.1°C) with little to no additional pressure.

Which grind size should you use?

Knowing the grind size to utilize for which brewing technique is critical to achieving the finest cup possible when using a variety of brewing methods. Taylor Martin is a contributor to CNET.

  • Turkish coffee needs a tiny grind size, similar to that of powdered sugar, in order to be effective. Espresso is produced by applying pressure (about 9 bar) to compacted coffee grounds in order to push water through the grounds. The contact period is extremely brief, necessitating the use of a very tiny grind size. TheAeroPressis a single-cup manual coffee maker that is quite popular. It’s designed and used in a similar fashion to a French press, however users have come up with a long number of creative methods to make coffee with it. In general, a medium to fine grind size is recommended, depending on the steeping period. Siphon brewers work by forcing water into a chamber containing the coffee grinds under pressure. Once the steeping process is completed, the heat is withdrawn, resulting in a vacuum in the bottom chamber and the water being drawn through a filter. The medium-fine grind size is required for this procedure. Pour-over brewers are available in a variety of sizes and styles to suit your needs. Variable brewers require different grind sizes to manage the pace at which water is dispensed
  • Nonetheless, the majority of pour over systems ask for a medium to medium-fine grind. In a stovetop espresso machine, also known as a Moka pot, steam pressure is used to drive water upwards through a filter basket filled with coffee grounds. In comparison to a conventional manual brewer, the contact duration is quite brief, but the pressure (about 1.5 bar) is slightly higher than in most cases. a medium grind size is required for this recipe A single-cup coffee maker, such as a Keurig or Verismo machine, uses a drip brewer method, which is comparable to the commercial drip brewers used in cafés and coffee shops throughout the country. The contact time is rather short, requiring a medium- to medium-fine grind size, similar to that of table salt
  • Dripcoffee is what you would generally get in a cafe or coffee shop because of the short contact time. Considering that it’s prepared in big quantities and that contact duration is governed by a small hole in the bottom of the brewing basket, the ideal grind size ranges from medium-coarse to medium. French presses are immersion brewers, and they are used to make coffee. A little amount of water is added to coffee grinds and let to steep for few minutes before the grounds are strained out. This procedure necessitates the use of a coarse grind setting. Cold brew, in contrast to other brewing processes, is done at or below room temperature and takes somewhere between 12 and 72 hours to complete the process. The extraction rate is poor because to the low temperature, which is true independent of the grind size. It is advised to choose a coarse or extra coarse grind size since it is simpler to filter. Even though a finer grind size will work just as well (and require a slightly shorter steep time), it may cause the finished product to seem a little hazy.

Of course, all of the advice listed above are only that: recommendations. They are susceptible to modify according on personal tastes and modest variations in brewing techniques. It will take some trial and error to get the grind size just perfect for your application. If you find that your cup of coffee is a little weak, experiment using a little finer grind size the next time you make it. Alternatively, if the coffee tastes excessively strong or little bitter, experiment with a slightly bigger grind size to see if that alleviates the problem completely.

Types of Coffee Grinds

The right grind is essential to making the ideal cup of coffee. The same way that there are several varieties of coffee roasts, there are numerous variations in the consistency and manner of grinding coffee. Using our thorough coffee grind guide, you’ll learn all you need to know about serving consistently great cups of coffee to customers while they’re enjoying their favorite meal. All Commercial Coffee Grinders are available for purchase. To skip forward and get answers to your specific coffee grinding questions, click on the following links:

Coffee Extraction

Coffee extraction is the process of diffusing the naturally occurring coffee solubles found in coffee beans into water. Lipids, carbohydrates, melanoidins, caffeine, and acids are some of the desirable coffee solubles that contribute to the development of rich tastes. If there are too few coffee solubles in the water that is used to brew the coffee, the flavor of the end product will be off. In contrast, if the solubles are allowed to over-saturate the water, the coffee you serve will not taste good.

The size of your coffee grinds has an impact on the method you choose to obtain optimal extraction.

This is neither good nor bad; you just need to change your brewing process to fit the different extraction rates of the different grind sizes.

The following are the coffee extraction words that you should be familiar with:

  • Coffee that has been under-extracted It is produced by grinding coffee beans too coarsely and does not provide enough coffee bean taste. Coffee that has been over-extracted It is produced by grinding coffee beans excessively finely, resulting in overwhelming and disagreeable tastes. Balanced Extraction is made from coffee beans that have been uniformly ground. The flavor of evenly extracted coffee is full of rich notes, has a balanced acidity, and has a silky mouthfeel.

What Makes Coffee Bitter?

Excessive extraction results in bitter coffee. In the event that coffee beans are ground too finely for their brewing technique, they are allowed to brew for an excessive amount of time, or they are brewed in excessively hot water, the grinds get over-extracted, lose their taste, and produce bitter cups of coffee. Under-extracted coffee, on the other hand, has a sour, salty, and acidic taste to it.

How to Make Coffee Taste Good

By attaining the optimal coffee bean extraction, you can make delicious cups of coffee every time.

We can supply you with the troubleshooting assistance you require to change bitter and sour tasting coffee into delectable drinks. Creating a Delectable Cup of Bitter Coffee:

  • Make use of coarser-ground coffee beans. Increase the temperature of the water and shorten the brewing time.

To Make Sour Coffee Taste Good, Follow These Steps:

  • Make use of finer coffee beans
  • Lower the water temperature
  • And extend the brew time to achieve the desired results.

Types of Coffee Grinders

Coffee grinders and espresso grinders are vital pieces of equipment for every coffee shop’s inventory list. There are four basic types of coffee grinders: burr, blade, roller, and hammering. Burr coffee grinders are the most common variety. Below, we’ll go through the characteristics that characterize each type of coffee grinder.

1. Burr Coffee Grinders

  • A device that presses coffee beans between two wheels or conical grinding components without generating frictional heat
  • Allows the oils in the coffee bean to be released, making them easier to extract during the brewing process. Produces coffee grinds that are very consistent
  • It has customizable grind sizes
  • You may modify the distance between the abrasive wheels/cones by moving them closer or farther apart. Note: Conical burr grinders create less frictional heat and retain more of the aroma of the coffee bean than disc grinders, but they are significantly more costly.

2. Blade Coffee Grinders

  • Chops coffee beans using a high-speed blade/propeller that spins between 20,000 and 30,000 revolutions per minute
  • The process frequently results in irregularly sized coffee bean grinds, making adequate extraction difficult
  • Coffee beans are heated by friction, resulting in a reduction in their taste quality even before they are brewed.

3. Roller Coffee Grinders

  • Two corrugated rollers are used to pass the coffee beans through. Produces coffee grind sizes that are considerably disparate, resulting in acidic and harsh cups of coffee. Exposes the coffee beans to a great deal of frictional heat, causing them to lose their aromatic properties

4. Pounding Coffee Grinders

  • By crushing coffee beans using a mortar and pestle, you may make a fine powder out of them. Very few coffee drinks require the pounding technique of grinding coffee, although Turkish and Arabic coffees are among those that do require it.

Coffee Grind Chart

Following your understanding of appropriate extraction, you’ll be ready to dig into our coffee grind chart for further information. Our coffee grind chart explains the differences between the different grind consistencies and when to use them in your coffee. When you’re ready to experiment with different grinds and extraction processes, consult our guide to hot beverage equipment to help you narrow down which machine is best for your purposes.

1. Extra Coarse Ground Coffee

The consistency of extra coarse ground coffee is similar to that of peppercorns. Fine coffee grounds take a long time to unleash their flavor, making them ideal for slow brewing methods like cold brew. Extra Coarse Ground Coffee is used for a variety of purposes. Extraction Rate (percentage):

2. Coarse Ground Coffee

The consistency of coarse ground coffee is similar to that of sea salt. Although coarse coffee grounds are not as difficult to extract as extremely coarse ground coffee, they will require longer brewing durations. Because coarse coffee grinding leaves a significant portion of the bean intact, it helps to maintain the flavor and fragrance of the beans. When it comes to coffee cupping, coarse ground coffee is the preferred grind of Q Graders. Q Graders are certified by the Coffee Quality Institute and are qualified to weigh coffee in accordance with the techniques and practices of the Specialty Coffee Association.

Coffee cupping is the practice of examining the tastes and smells of freshly brewed coffee that is used by professional Q Graders.

The following are some applications for coarse ground coffee: Extraction Rate (percentage):

3. Medium-Coarse Ground Coffee

The consistency of medium-coarse ground coffee is similar to that of coarse sand. When using medium-coarse ground coffee, filter your beans gently so that they get thoroughly soaked with coffee flavor. Uses for medium-coarse ground coffee include: Extraction Rate (percentage):

4. Medium Ground Coffee

Medium-sized coffee grinds have the appearance of normal sand. Having a consistency that is in the center of the road almost never results in either over or under extraction. Medium-ground coffee beans are the simplest approach to produce a balanced extraction with the least amount of effort. While the taste payoff of medium ground coffee is smaller than that of other grinds, it is an excellent choice for establishments who do not specialize in coffee but want to offer balanced brews to accompany their dessert.

  • Brewers with flat bottom filters, single-serve brewers, vacuum brewers, and stovetop brewers are all options.

Extraction Rate (percentage):

5. Medium-Fine Ground Coffee

Medium-fine ground coffee has a consistency that is between between the sand consistency of medium ground coffee and the sugar consistency of fine ground coffee. Suitable for use in pour over coffee brewing, these coffee grinds are excellent quality. You can make wonderfully extracted cups of coffee with medium-fine grinds if you’ve mastered the pour over technique. Uses for medium-fine ground coffee include:

  • Pour Over Brewers
  • Drip Brewers with Cone-Shaped Filters

Extraction Rate (percentage):

6. Fine Ground Coffee

Your finely ground coffee should have the appearance and feel of sugar. You should only use this consistency of coffee grounds for brewing procedures in which the grounds only have a brief contact with the water; otherwise, you will end up with an over-extracted finished product. Fine grinding produces the most consistent grind uniformity for espresso. Espresso machines work by building up pressure, which drives water through finely ground coffee to produce espresso. Finely ground coffee has a variety of applications.

7. Extra Fine Ground Coffee

The consistency of extra fine ground coffee should be similar to that of powdered sugar. Commercial coffee grinders are not often capable of producing such a fine grind as described here. Extra-fine coffee grounds are required for just a few varieties of coffee, and they are only used in very small quantities. If you anticipate using a large quantity of this coffee ground consistency, look for a grinder that produces extra-fine coffee grounds. Extra fine ground coffee is used for a variety of purposes.

How to Store Ground Coffee

Ground coffee should be stored in an airtight container that is not transparent. Place the container of ground coffee on a pantry shelf where it will be protected from heat, light, and humidity.

Storing Coffee in the Freezer

It is never a good idea to put coffee that you use on a regular basis in the freezer. When you keep coffee for daily consumption in the freezer, you expose it to temperature fluctuations that cause moisture to form. Moisture alters the cell structure of the coffee bean, resulting in a diminished fragrance and flavor. Unless you plan to consume or disturb the beans during that time period, you can keep whole coffee beans in the freezer for up to a month. Before freezing your coffee beans, separate them into little amounts and store them in sealed plastic bags until needed.

Within two weeks after thawing your coffee beans, grind and brew them as soon as possible.

How Long Does Coffee Last?

Whole coffee beans have a shelf life of two to three weeks before their quality and taste deteriorate significantly. Pre-ground coffee, on the other hand, retains its optimal freshness for around 30 minutes after it has been ground. Because coffee beans are the seeds of the little cherries that grow on coffee plants, you should approach the freshness of coffee beans in the same way you would any other plant-based food product. Like cutting pineapple and serving it to visitors three months later, grinding coffee and serving it to guests months later is also not a good practice.

Make consistently great cups of coffee by following the recommendations in this guide to finding the proper grind size for your brewing technique.

To ensure balanced extraction and satisfy visitors with smooth and rich cups of coffee, grinding your coffee beans is the most cost-effective method available to you.

Refer to our coffee grind chart to ensure that the coffee grind consistency is appropriate for your brewing technique and operational requirements.
