Why Does My Coffee Taste Bitter? (Solution)

Bitter coffee comes down to two things: (1) bad beans and (2) bad brewing. If you buy low-grade, robusta species, or super dark roast beans—I’m sorry—but there’s nothing to be done there. Low-quality coffee just tastes bitter, which is why we suggest buying specialty-grade beans (the highest quality grade).

How do you take the bitterness out of coffee?

To reduce the bitterness of your coffee, try adding cream, milk, or sugar to offset the bitter flavor. Alternatively, mix in a sprinkle of salt. You won’t be able to taste the salt, but it should reduce the bitterness. Another reason your coffee might taste bitter is because you’re boiling the temperature too high.

Why does my coffee suddenly taste bitter?

The bad taste comes from the acids in the bean dissolving early in the brewing process. If your coffee tastes super bitter, your drink may be over-extracted. This happens most often with too fine of a grind. Depending on the type of coffee you’re brewing, you may need to adjust the size of your grounds.

How do you make instant coffee not bitter?

It’s simple — mix the instant coffee mix with a little cold water before adding any hot water. This will help cut down on the acidity and bitterness that comes with the instant coffee territory.

Why is my coffee bitter and sour?

Sour coffee comes down to two things: (1) bad beans and (2) bad brewing. If the beans are under-roasted, they’ll taste grassy and sour. But, chances are, you’re beans are fine—which means you need to make a small adjustment or two to how you make your coffee. Sour coffee is usually under-extracted coffee.

What coffee is not bitter?

Which coffee beans make less bitter coffee? Arabica beans make coffee that is less bitter than Robusta beans. With Arabica beans, you can brew coffee with less bitterness and more flavor although they are a bit pricier. To make a less bitter cup, you can also try beans from Kona region, Brazil or Costa Rica.

Why is restaurant coffee so good?

Most fine restaurants use a press pot, also known as the French Press, which produces an extremely rich cup of coffee. Press pot coffee is coffee steeped for 3-4 minutes between 195 to 205°F. It produces a thicker and much richer taste than an auto-drip machine can produce.

How do you make instant coffee less acidic?

Add baking soda Baking soda, or sodium bicarbonate, is a natural antacid. It can help neutralize some of the naturally occurring acid in your cup of coffee. As little as a 1/4 teaspoon of baking soda for a cup of coffee can smooth the flavor and make it easier to digest.

Is pour over coffee more acidic?

The only difference is that the phrase “pour over” is used when you’re only making one cup. The extraction process is based on fineness of grind, temperature of the water, and the amount of time for the brewing. There should be no difference in acidity between a properly made pot of drip coffee or a pour over.

How do you fix acidic espresso?

Remedy: To fix a sour espresso shot, adjust your grind to be finer. This will mean that when you tamp the grinds you’ll create more resistance for the water to pass through allowing it to pick up more oils along the way.

4 Reasons Your Coffee Tastes Bitter

Having poured a large cup of coffee, putting it to your lips, taking that first delicious taste, and finding that it is bitter as sin is the worst feeling in the world. Your morning brew ought to be a blast of wonderful flavor, not an overbearing dosage of bitterness. So what causes it to be bitter in the end? It’s interesting to note that bitterness is frequently connected with coffee. If you drink a truly nice cup of coffee, you’ll notice that the bitterness isn’t the prominent flavor at all.

As a matter of fact, there is a whole flavor wheel dedicated to defining good coffee.

Why Coffee Tastes Bitter: The Technicalities

Coffee brewing is an art and a science, and excessive extraction is the most common cause of bitter coffee. Extraction is the process by which the taste of the coffee is extracted, resulting in the transformation of clear water into that wonderfully black drink. When water is mixed with coffee grounds, a chemical reaction occurs, dissolving the taste compounds in the coffee grounds. The key is to extract the excellent flavors, rather of the bitter ones, which come out with more time. With that in mind, here are a few factors that might be contributing to that unpleasant cup, and that you can simply avoid next time.

1. You’re letting your coffee steep for too long.

Especially prevalent when preparing French press coffee, since many people have a propensity to leave the coffee in the French press after they have pressed the plunger all the way down to extract the coffee. Because the coffee will continue to extract if you do this, your second cup of coffee will almost certainly be more bitter than your first. In order to enjoy your coffee more slowly, transfer it directly to a thermal carafe in order to keep it hot longer than usual.

2. You’re using the wrong grind size.

Grinding coffee beans modifies the way flavor compounds dissolve, which means that if the beans are crushed too coarsely, you run the danger of under-extraction and, as a result, a flat or sour tasting cup of coffee. However, if they’re ground too finely, you run the danger of getting an over-extracted, bitter cup of coffee. When it comes to grinds, each technique will require a little different grind; occasionally you’ll need to experiment to find the sweet spot; nevertheless, if your cup is bitter, it’s likely that your grounds are a touch too finely powdered.

According to the National Coffee Association, a temperature range of 195°F to 205°F is best for maximum extraction.

4. Your equipment is dirty

Bitterness is caused by a variety of factors, not only over extraction. Coffee residue left behind from the last time you brewed can have a significant impact on the flavor of subsequent cups of coffee. Make certain that your brewing equipment is kept in good condition.

3 reasons your coffee tastes bitter

Coffee has a natural bitterness due to the presence of caffeine in it, however caffeine accounts for just around 10-15 percent of the bitterness in a cup of coffee. A low amount of bitterness really aids in taming the acidity of the coffee. We do, however, recognize that overwhelming bitterness or an uneven cup of coffee might be frustrating to the customer. So, what is it about your coffee that is bitter? The bitter taste that remains in your tongue after drinking coffee is frequently caused by one or a combination of the following three factors, according to Perth’s greatest coffee enthusiasts:

1. Over extraction

When we brew coffee, the flavor is determined by the amount of solids extracted from the coffee bean itself. The amount of total dissolvable solids in your espresso, as well as the evenness of the extraction, affect how nice your espresso will taste. The key to attaining the right brew ratio is to strike the right balance between the amount of ground coffee and the amount of water utilized. Too little water results in sour, under-extracted coffee, while too much water results in bitter, over-extracted coffee, according to the manufacturer.

(coffee:water).

Volumetrics and coffee machine programming

In our daily routine, we make it a point to check the volumetrics on the coffee machine. Volumetric programming guarantees that our coffee maker dispenses the exact quantity of water for the dose we are using by monitoring the amount of water dispensed. For uniformity in their espresso production, we propose that baristas weigh their espresso output. As is always the case, weighing your dosage is critical to maintaining your brew ratio and producing the ideal cup of coffee.

2. Grind Size

The grind size of our coffee has a significant impact on the overall taste of the coffee, much as the brew ratio has an impact on espresso extraction. It is important to note that using a grind setting that is either too fine or too coarse will have a major impact on the flavor of your espresso. When espresso is poured too quickly, it results in under extraction. Because the coffee solids have more time to dissolve in slower-pouring espresso, the flavor of the espresso gets stronger – but only up to a point.

It is necessary to coarsen the coffee grinds in order to prevent the water from becoming too constricted.

3. Dirty machine and equipment

It’s a no-brainer, really.

DIRTY EQUIPMENT = BAD TASTING COFFEE

If oils are not removed from your coffee maker on a regular basis through routine cleaning, they will begin to get rancid. Flavors such as metallic, bitter, or astringent in coffee are frequently attributed to either the barista or the coffee beans. In reality, they are frequently caused by contaminated equipment. We frequently hear that a machine with minimal utilization does not require the same level of cleaning or maintenance as a machine with heavy usage requires. This is not entirely correct.

A coffee machine that is not used will accumulate oil at the same rate as a coffee machine that is used often.

In part, this is due to the increased amount of idle time; because there is no water to flow through the various sections, oil accumulates rapidly. If your net showers and group head assembly become clogged with coffee, you may need to clean them out.

Backflushing your coffee machine

In order to keep your coffee machine running efficiently, we recommend that you backflush it as often as possible during the day. To close off the day, backflush each group head with a specialized coffee machine cleaning and rinse well. If not cleaned correctly, dirty portafilters and baskets can also cause coffee to taste ashy and bitter, resulting in a bitter taste. During servicing, you should clean these components on a regular basis. Toss them in a hot bath with dishwashing liquid at the end of the day, then scrub and rinse them before placing them back in the machine to dry.

Don’t forget your coffee grinder!

Doser coffee grinders must be completely cleaned to remove any remaining coffee grinds from the machine. Additionally, coffee beans must be stored in an airtight container or bag overnight to prevent spoilage. More information about coffee storage may be found here.

Some other things to consider:
  • Check to see that the coffee beans you’re using are still fresh. It is advisable to wait 1-2 weeks after roasting
  • Try a lighter roasted coffee
  • And make sure your water is of high quality. Water filters should be replaced on a regular basis. It is important to ensure that the temperature does not rise too high
  • The ideal range is between 92 and96 degrees.
How can I make my coffee stronger but not bitter?

Take care to use only freshly roasted coffee beans. It is advisable to wait 1-2 weeks after roasting; try a lighter roasted coffee; and make sure your water is of high quality before drinking. Regular replacement of water filters is recommended. It is important to ensure that the temperature does not rise too much; the ideal range is between 92 and96 degrees.

The Road To Redemption

THE ISSUE AT HAND: It is one of the most typical causes for your coffee to taste bitter that it has been over-cooked. Coffee, like tea, gains its taste by being steeped in hot water for a period of time. If you let it to steep for an excessive amount of time, too much of the harsh tastes will come through, and your coffee will taste burned and bitter. THE SOLUTION: Knowing how long to brew for your chosen brewing technique is essential, as is setting a timer so that you can tell when it’s time to drink the good stuff.

2. IN (TOO) HOT WATER

THE PROBLEM: A large number of individuals bring their water to a boil and then immediately begin brewing. However, 212°F is really too hot for the brewing of coffee!

13 Reasons Your Coffee Tastes Bad and How to Fix it

We’d want you to know that if you visit RoastyCoffee.com and decide to purchase a product, we may receive a small compensation. After all, we all have down days. And occasionally those terrible days manifest themselves in the shape of coffee that doesn’t taste good. Moreover, it’s not awful in the sense of “you’ll never get those beans again,” but bad in the sense of “this is my favorite coffee, and something has gone horribly wrong.” That’s OK with me. It does happen. And we can assist you in learning how to avoid repeating the same error in the future.

Coffee brewing is both an art and a science in its own right. Once you understand the most frequent mistakes people make when it comes to coffee beans, water, and equipment, you can rectify them and get back to brewing delicious drinks.

Common Coffee Conundrums

If your coffee isn’t brewing as well as you’d like it to, there are a variety of reasons for this. Here’s a short rundown of the reasons behind this that we’ll cover in further detail later in this article:

  1. It has everything to do with the coffee beans. Your water isn’t of the highest quality
  2. A issue has arisen in the operation of your equipment.

Continue reading to learn how to differentiate between these typical issues and precisely identify the problem with your coffee brewing.

The Beans are the Problem

Never underestimate the significance of high-quality coffee beans in making a delicious cup of joe. You may already be aware that we are strong advocates for grinding your own coffee beans, but even the best coffee beans can occasionally be a contributing factor to a terrible cup of coffee.

1. Your Beans Aren’t Fresh

The shelf life of coffee is limited, no matter how fresh the beans appear or how lightly they smell when they are first purchased. As soon as those small pockets of bliss are removed from the roaster, their flavor begins to fade away. Coffee beans release a significant amount of carbon dioxide during the roasting process. Degassing is the term used to describe the process by which carbon dioxide is released. The longer they are allowed to degas, the more flavor is released. If your coffee beans have been neglected in the back of a cupboard for a year or have been incorrectly kept, it is possible that this is the cause of your disappointing cup of coffee.

That’s a significant amount of taste loss.

2. The Roast is Bad

If you’re re-roasting your own beans, this might be the source of your terrible coffee. Roasting is a difficult technique that necessitates the application of constant heat throughout the roasting duration. Despite the fact that you can roast your own beans at home, you will need to build an atmosphere that closely resembles the equipment used by a professional roaster. However, there are situations when you have no control over the quality of your roast. Even the best roasters make blunders (we’re all only human after all).

That’s right, you read that correctly.

In essence, even the most sophisticated commercial coffee roasters have difficulty roasting beans uniformly.

3. The Coffee is Low Quality

Even though we all enjoy a good deal, skimping on your coffee bean budget might come back to get you in the you-know-what. Robusta coffee beans are often thought to be of poorer grade, however this distinction is based more on the flavor of the bean than on the actual quality of the bean. Robusta coffee is less nuanced and delicious than arabica coffee, so if you discover that robusta beans don’t quite satisfy your expectations, you might want to try switching to arabica beans. In addition to the variety, there is the specific bean and roast to consider.

What to Do to Fix It: It is vital to understand how to get the best coffee beans. Pre-ground coffee with ambiguous labelling should be avoided at all costs if you want to experience new and exciting flavors in your coffee.

4. Your Grind is Too Big/Small

The way your coffee beans are ground may make a significant impact in the flavor of your cup of joe. Why? Coffee grinds must be soluble enough to provide taste while being insoluble enough to avoid clogging your filter system. If your coffee feels weak or sour, it’s possible that it was not properly extracted. This is due to the acids in the bean dissolving early in the brewing process, resulting in an unpleasant flavor. Large coffee grounds might contribute to this disagreeable flavor since they have a larger surface area and do not dissolve completely throughout the brewing process.

The most common cause of this is a grind that is too fine.

This video shows you how to grind coffee beans for espresso.

Water is the Problem

After the beans, it’s possible that the water you use is a significant factor in how horrible your coffee tastes. Water that tastes great to you may still be an issue even if you often drink water directly from the faucet and it does not bother you.

5. Your Temperature is Wrong

Although it may appear random to the untrained eye, we will never weary of advocating for the ideal temperature for brewing coffee. We suggest 205 degrees Fahrenheit (96 degrees Celsius) for any cup of coffee. Why? Ideally, you want your water to be warm but not boiling. If you cook your beans too long at a high temperature, the volatile oils and nuanced tastes will be destroyed. If the temperature is too low, your coffee will come out under-extracted. which is weak and not a good way to start your day.How to Fix It: This is a simple problem to solve.

Whether it’s a regular thermometer or a high-tech laser thermometer, what happens if you ever find yourself without a thermometer?

6. Your Tap Water isn’t Great

Although it may appear that your tap water is fine to you, the presence of particles in your water can have a significant influence on the flavor of your coffee. Making coffee is similar to solving a chemical issue. When you put unknown components into your equation, it is possible to cause it to fail. What to Do to Fix It: This is another another straightforward solution. Filter the water you use to make your coffee before you start brewing it. Keep in mind that many tap water filters must be operated at a low temperature in order to function properly.

Equipment is the Problem

So your beans and water are both okay, but there’s still something wrong with the system. If that’s the case, it’s possible that your equipment is the source of the foul taste in your coffee.

7. Your Equipment is Dirty

It’s understandable that you don’t feel the need to clean it every time; after all, you merely prepared coffee. Isn’t it just a simple rinse that will fix everything? No, not at all. For those of you who have never cleaned a coffee maker, this is a good time to start. This is due to the fact that we are accustomed to solely thinking about the coffee pot and the filter area. Have you ever cleaned the reservoir of your drip coffee maker?

When was the last time you did so? If you can’t recall, it’s likely that it’s time to give your coffee equipment a thorough cleaning. What to Do to Fix It: Maintain the cleanliness of your coffee machine. Your taste senses, as well as your immune system, will appreciate it.

8. Your Equipment is Old

You may be sure that your coffee maker has remained by your side through thick and thin. It provided you with a small cup of bliss on even the most difficult of days. However, no one or anything is immune to the dangers of old age. Especially if the quality of your coffee suddenly deteriorates for no obvious cause, you should take note of this. Your beans are fresh, your water is filtered and heated properly, and your equipment has been well cleaned recently; everything is in working order. This suggests that you may require a new coffee maker if this is the case.

Begin looking for a new coffee maker or grinder as soon as possible.

9. You Used the Wrong Equipment

You may be sure that your coffee maker has been by your side through thick and thin with you. Regardless matter how bad things were going, it provided you a tiny cup of bliss. The dangers of growing older, however, affect everyone and everything. If the quality of your coffee suddenly deteriorates for no obvious cause, this is very important to keep in mind. Besides having decent beans, you also have clean water that has been filtered and heated correctly, as well as recently cleaned equipment.

It can be fixed in several ways.

Find a replacement coffee machine or grinder as soon as possible.

Something Else Went Wrong

So it turns out that your beans, water, and equipment aren’t the issue. That’s OK with me. Because brewing coffee might be difficult, there could be other factors contributing to the unpleasant taste of your coffee.

10. Your Timing is Off

In the case of herbal tea, you may not mind if the tea steeps for a few minutes longer than you intend it to. That is not the way things operate when it comes to coffee. It’s possible that you’ll end up with over- or under-extracted coffee if your brew is either too short or too lengthy. For example, you can make percolated coffee between six and ten minutes depending on the amount of time you have. That represents a significant temporal variable. In order to identify the most effective brewing method while testing a new recipe, some experimenting may be required.

13. You Don’t Even Like That Kind of Coffee

Keep in mind that coffee is all about your individual preferences. Don’t push yourself to drink coffee that doesn’t appeal to your taste buds. What to Do to Fix It: Change up the recipe, experiment with various beans, and see what you like most.

What If My Coffee Tastes…

The temperature of the water has the potential to significantly impact the brewing process. Other things, on the other hand, may produce a disturbance in the flavor of your coffee. If you’ve maintained your equipment clean and your coffee beans are fresh, but you’re still getting a strange flavor from your coffee, it’s possible that there are additional elements at play.

Bitter?

It is possible that your coffee can taste bitter if you use too hot water while brewing it. Other variables, such as stale beans, brewing for an excessive amount of time, or a too-fine grind, can also contribute to a bitter flavor. Some suggestions for resolving this issue include adding milk or sugar to the coffee, or even a small bit of salt to bring out the natural taste of the coffee.

Sour?

The bitterness of your coffee might be increased if you use too hot water while brewing it. Another element that contributes to a bitter flavor is stale beans, brewing for an excessive amount of time, or a fine grind. Add milk or sugar to the coffee to make it sweeter, or even a pinch of salt to bring out the natural taste of the coffee to cure the problem.

Burnt?

A burned flavor is usually caused by overroasted beans (which can happen before you even purchase the grinds, so that’s quite unlikely), or by overcooking the coffee, which is not recommended. This can also happen if you brew your coffee with too much hot water for an extended period of time. Immediately following brewing, it is recommended to keep your coffee as warm as possible. Keeping it boiling hot will only serve to degrade the flavor of the dish.

Metallic?

If it is not caused by a build-up of debris in your machine, this phenomena is frequently caused by an issue with the flavor or quality of the water being utilized. This is an issue that might arise frequently for individuals who make their coffee with ordinary tap water. Because tap water can include traces of chlorine and other impurities that can change the flavor of the water, brewing with filtered or bottled water is the best option.

Watery?

Drinking coffee that has been watered down is unpleasant and can be caused by a variety of circumstances. These reasons include not using enough coffee to brew, not brewing for a long enough period of time, not brewing at a hot enough temperature, and using a grind size that is too tiny. To combat this, start by altering the ratio of coffee to water in your cup. Once you’ve done that, you can look at your brewing time, grain size, and water temperature.

Like Plastic?

The most likely cause of a plastic flavor in your coffee, if the fault isn’t with the water or brewing process, is your coffee maker. Machines might produce this plastic flavor when they are first installed or when they have been abused and have not been given a thorough cleaning every now and then. The most effective solution is a thorough cleaning of your equipment.

Wash your water reservoir (because these are typically made of plastic) and put your coffee machine through its paces with hot water. If you like, you could also use 50/50 white vinegar and water, 50/50 baking soda/water, or 50/50 lemon juice and water to create a cleansing brew cycle.

Now You (Probably) Know Why Your Coffee Tastes Bad

You should replace your coffee maker if your coffee has a plastic flavor and you have determined that the issue is not with your water or brewing process. Machines that are brand new or that have been misused and have not been given a thorough cleaning every now and then might produce this plastic flavor. Generally speaking, deep cleaning your computer is the most beneficial option. Wash your water reservoir (because these are typically made of plastic) and put your coffee maker through its paces with hot water to get it started!

Bitter, sour or just nasty?

The enjoyment of a good cup of coffee might be jeopardized by any number of circumstances. If you have hard water, it may cause sediment to accumulate in your cup. Brew coffee that is left out in the open will rapidly go stale. Failure to adequately extract the flavors from your beans may leave you with a sour aftertaste in your mouth. Bitterness, on the other hand, is something quite distinct. It’s the type of flavor that causes you to make a funny face and put your cup down. In this case, it’s the result of a specific defect in the brewing process: excessive extraction.

Common Reasons Why Your Coffee Taste Bitter

Lucky Belly is shown in this image. A coffee bean’s bulk will dissolve in water to an extent of approximately 28% of its mass. The remainder is made up of cellulose and plant fibers. It is the simple step of combining the beans with water that transforms them into your favorite beverage. During the brewing process, distinct tastes are extracted from the coffee bean at different stages of the process. And not every one of those tastes is pleasant. In order to create the perfect brew, you must include all of the wonderful flavors while eliminating all of the negative.

It will have a sour and maybe salty flavor to it. In contrast, over-extracted coffee will leak bitter-tasting chemicals into the water as a result of the extraction process. Horrid! As a result, what precautions should you take to avoid over-extraction?

2. Get the temperature right

Lucky Belly is shown in this image. It is important to brew your coffee with the appropriate temperature water in order to avoid bitterness. The hotter the water is, the more quickly the coffee bean will be broken down by the water. There is a critical link between water temperature and brewing time, as seen above. Using too much heat in the water may cause the beans to scald themselves. It will also release the various flavor-enhancing chemicals in a very short period of time. As a result, it will be difficult to keep the bitter compounds produced later in the brewing process from making their way into your cup.

Temperatures between 195 and 205 degrees Fahrenheit are ideal.

Because it utilizes cold water to extract the flavors, it is more environmentally friendly.

3. Don’t leave it too long

Lucky Belly is depicted in this photograph. It is important to brew your coffee with the proper temperature water in order to avoid harsh taste. Amount of time it takes for water to break down a coffee bean depends on the temperature of the water. Because of this, there is a critical link between water temperature and brewing time. The beans can be scalded if the water is excessively hot. The diverse flavor-enhancing chemicals will be released in a short period of time as well. Consequently, avoiding the bitter compounds that are produced later in the brewing process from ending up in your cup will be difficult.

195 to 205 degrees Fahrenheit is the target temperature.

owing to the fact that the tastes are extracted using cold water

4. The daily grind

Your coffee grounds’ size has an impact on the flavor of your coffee, so make sure you use the right amount. The more finely ground the coffee, the faster the flavors will be extracted from the beans. Different grind sizes are appropriate for various brewing styles. For a French press, a coarser grind will be required, but for Turkish coffee, a very fine grind would be required. However, whatever of the method you use, make sure the water does not come into touch with the coffee for an extended period of time.

This YouTube video demonstrates the relationship between grind size and extraction time.

5. The right mix

The proportion of water to coffee in your brew is also highly crucial for flavoring your coffee. It is, strictly speaking, the strength of the coffee that is at issue here. The amount of coffee you put in the same amount of water will determine how strong the drink is. However, it is not the entire story. Caffeine is present in higher concentrations in a stronger brew, and caffeine can have a bitter flavor. It’s also worth noticing the quality of the coffee. Individual varietals will have distinct tastes, and differing roast characteristics will have an impact on those flavors, as would other factors.

Robusta beans have a more bitter flavor than other types of beans. If you make coffee with a high proportion of Robusta beans to water, the result will be a bitter beverage. Note that this isn’t need to be the case at all.

8 Reasons For Bitter Coffee (and How to Fix)

In accordance with current statistics, 54 percent of Americans consume coffee (1) on a daily basis. As far as my personal statistics go, 99 percent of people are unable to operate well without coffee (I’ve got one next to me right now in a cup that reads, “Please do not speak to me until I’ve had my coffee”). Nobody is born a coffee enthusiast. It takes time to develop a taste for it, much like great wine. Despite the fact that coffee is inherently bitter, there are instances when your face may pucker up after sampling a new brew because it is simply too bitter.

Following that, we’ll look at eight sources of that bitter taste and strategies to eliminate it.

1. Over-Steeping your Coffee

Steeping refers to a method of brewing coffee in which you immediately blend your coffee grounds with the water before brewing (as opposed to passing it through a filter). For example, the French Press and the AeroPress are both examples of ‘press’ coffee machines, and it’s typical in most of them. The risk, on the other hand, is not understanding how long to steep your coffee for, since if you over-steep your coffee, you will end up with a bitter, harsh flavor. This is due to an excessive amount of extraction.

The coffee will be weak and unpleasant if you extract too little from the coffee bean.

Reduce the amount of time you spend steeping.

2. Dirty Equipment

This one should go without saying – keep your s**t clean! It is acceptable to rinse your French press after each usage (as long as you back-flush the filter mesh thoroughly). When utilizing an automated drip coffee maker, it is important to run clean, fresh water through it at least once a week to ensure that the smelly “coffee from yesterday” taste is completely removed from the final product. Aside from the obvious health benefits, high water quality is essential if you want to brew coffee that tastes nice.

Give it a thorough cleaning.

This is especially important if your filter cone has grooves and ridges inside to aid in the drawdown process. A brush with a long handle and a little amount of baking soda

3. Your Grind and Brewing Methods Don’t Align

The art of brewing excellent coffee takes practice. With tremendous power comes great responsibility, and you’ll need to know your perfect grind setting before you can do anything else. Although you will have tight control over grind size with a decent burr grinder, you will also have the flexibility to experiment with different sizes until you discover one that works for you. As a result, your coffee will taste just as it should – without the extraction of bitter components that might detract from the flavor.

Grind Size Brewing method
Coarse French Press Percolator
Medium Your regular household coffee maker with flat filters
Fine Coffee Makers with Cone Shaped Filters
Extra Fine Pump and Steam espresso machines

As a general rule, finer grinds extract more flavor but also contribute more bitterness, whereas a coarser grind produces a lighter, sweeter drink. A scientific reason for this may be found in the fact that more than 1800 chemicals contribute to the flavor of a cup of coffee (2). Some are removed very fast, from the surface of the grinds, but others are retrieved from the inside of the grinds, which requires more time and effort. By altering the grind, you may alter the relative extraction of the inner and surface components in the blend.

The solution: If bitterness is your adversary, then grinding a little rougher may prove to be your closest friend in the fight against it.

4. Unreliable Water Clarity and Temperature

We’re all aware that coffee should be served hot when it’s made. Nevertheless, did you know that elements such as water type and temperature play an important part in producing the ideal cup of coffee? You must be extremely conscientious about the amount of water you consume! When using unfiltered water, it is rather simple to spoil a perfectly brewed cup of coffee. Because of the lack of minerals in distilled water, it is also not recommended for consumption. Bottled spring water is the greatest option because it does not have a discernible flavor.

The ideal temperature is between 195 and 205 degrees Fahrenheit.

If you have a drip coffee machine, this may not be necessary.

5. Using Old, Stale Coffee Beans

The preparation of coffee should be done in a timely manner, as we all know. But did you know that parameters such as water type and temperature have a big impact in producing the ideal cup of tea? When it comes to water, you must be extremely careful! With unfiltered water, it is quite simple to destroy a well made cup of coffee. Because of the lack of minerals in distilled water, it is also not recommended for usage. Bottled spring water is the greatest option because it does not have a detectable flavor.

Ideal temperature is between 195 degrees Fahrenheit and 205 degrees Fahrenheit. Temperatures near 205 F are preferable since bitterness is more noticeable in water that is colder in temperature. Although it is possible that you may not have a drip coffee machine,

6. Maybe You Just Haven’t Found the Right Roast…

The rule of thumb is that dark roasts have a bitterer flavor than lighter roasts. Did you have the black French roast that a buddy raved about, too? If you find yourself biting on a chunk of charcoal straight from the BBQ, a lighter roast may be more to your liking. Coffee you enjoy is the only criteria that matters when it comes to “excellent coffee.” If you don’t like something, you shouldn’t force it onto yourself. Once again, science comes to the rescue: it is not only the grind size that can lead to a bitter cup, but also the way the coffee is roasted, which is a significant impact (4).

As a result, the more intensely you roast the coffee, the harsher it tends to get.

7. The Source and Variety of Beans Make a Huge Difference

There are two types of coffee plants grown: Robusta and Arabica. Robusta is the more common of the two. Robusta is far more bitter than Arabica and contains significantly more caffeine; but, since it grows more quickly and is more resistant to pests, it is typically less costly. Arabica yields beans with a stronger flavor, but the plants demand more attention, which increases the cost of production. If you are sensitive to bitterness, though, you should seek for Arabica beans. Not that tough; most premium coffee bean sellers specialize on Arabica and will indicate this on their labels or websites.

Here are a few examples of particular suggestions: Beans from the Kona region, either Brazilian or Costa Rican.

8. The Ratio of Water to Coffee

When you were a youngster, it’s likely that you discovered that adding more sugar to your tea made it taste better. Right? When it comes to brewing coffee, the idea is precisely the same, but in the opposite direction: adding more coffee to your water might make it bitter. The Specialty Coffee Association of America refers to what they refer to as their “golden ratio,” which is a balance of beans to water that they believe results in the best possible cup of coffee: 55 grams of coffee per liter of water results in an 18:1 ratio — that is, 18 grams of water for every one gram of coffee brewed.

Ask a lot of baristas, and they’ll tell you that their favourite ratio at their coffee shop ranges between 16:1 and 18:1.

The Verdict

Not to mention the fact that coffee is inherently bitter, which is what gives it its characteristic “kick.” However, if your coffee is really bitter (as in intolerably bitter), keep in mind what you have just learned:

  • If you’re using a ‘press’ maker, be careful not to oversteep your coffee. Make use of clean equipment. Make sure you use the proper grind for your brewing process. Water that is not too hot, not too cold, and most importantly, not filthy
  • Replace the dark roast with a lighter roast
  • Try coffee from places that are recognized for creating a lower-acid, smoother cup of coffee. Attempt different coffee to water ratios until you discover the one that works best for you.

So, the next time someone asks you “why is my coffee so darn bitter,” you’ll know what to say.

Your ability to explain will be that of the coffee hipster you were destined to be!

FAQs

Compared to Robusta beans, Arabica beans provide a less bitter cup of coffee. Arabica beans produce coffee with less bitterness and greater taste, but they are more expensive than other types of coffee beans. Consider using beans from Hawaii, Brazil, or Costa Rica to make your cup of coffee taste more pleasant. Yes, adding salt to your coffee can help to make it less bitter. It was discovered that salt is a greater bitterness-neutralizer than sugar, according to one study (5). Salt has a natural ability to reduce the harshness of coffee while also increasing its flavor.

Yes, light roast beans produce less bitter coffee than dark roast beans.

Light roast coffee drinks are also less expensive.
