Does coffee smell like chocolate?

But, depending on where the beans are grown and how much they’re roasted, the coffee can have some flavor “notes” in it like fruit, floral, tobacco, chocolate and more! If a flavor is next to another it means that they are closely related and are more likely to be found in the same cup of coffee.

Advanced Coffee Tasting: What Your Coffee Smells Like

This month, we’ve spoken a lot about how to become a better coffee taster, and perhaps by now, you’ve had the opportunity to put your newfound knowledge to the test with some comparisons or at the very least some concentrated and conscious slurping. However, although it is vital to exercise your tongue, it is also important to exercise your nose. Time to go a bit further into the intricacies of coffee’s aroma and learn about some of the key features that expert tasters seek for in a cup of java.

The three major types of aromatic chemicals present in roasted coffee are asenzymatic, sugar browning, and dry distillation, and we’ll go through each of them today.

It can be tough to pinpoint the details of a flavor without any assistance, but once you begin to associate flavors in coffee with other items you consume on a regular basis, unlocking the brew’s mysteries becomes a little more achievable.

One of the most significant components of tasting, however, is the sense of smell, and if you don’t know how to use your schnoz properly, the entire process may be lost on your.

Enzymatic aromas are the most common.

However, we can smell something like a garden pea, chocolate, or anything else that specifically triggers a sense (and scent) memory.


Aromas such as onion or herbaceous are believed to be enzymatic. rageforst has a Flickr account. As a result of the fact that the coffee bean that we roast, ground, and brew is really the seed of a cherry-like fruit, it is reasonable to imagine the seed maintaining some of the fruity or plant-like characteristics of the fruit from which it came. Enzymatic qualities are what give coffee its flowery, fruity, and herbaceous fragrances, which are defined as “enzymatic” features. These are derived from the bean’s plant life and can have a variety of flavors ranging from oniony to melony, from jasmine rose to citric to berry-like.

However, as a general guideline, many Latin American coffees have a sweet red berry flavor to them, whereas coffees from Ethiopia can have a lemongrass flavor to them and coffees from Kenya might have a tomatoey acidity to them.

Sugar Browning

Toasted bread has a lovely, delightful sugar-browning quality that makes it taste even better. Maillard reactions are among of my favorites, according to John McClumpha on Flickr It’s called “sugar browning” in our language, and it refers to the delectable alchemy that transforms bread into toast while turning sugar into caramel. In the case of coffee, this is the chemical reaction that occurs when specific amino acids and sugars are subjected to high temperatures, such as during the roasting process.

(Excuse me while I sit here wondering about maple syrup, honey, and chocolate for a brief moment.

Dry Distillation

It’s “charred” rather than “burnt.” Robyn Lee is a young woman who lives in the United States. Roasting coffee beans is a dynamic and sometimes painful procedure for the beans, just as boiling any raw ingredient is for the final product. Fiberous bean material burns in the roaster, releasing fragrant by-products that are evocative of wood, tobacco pipe tobacco leather clove or black pepper when the beans are roasted. Due to the fact that coffees are roasted significantly lighter for cupping analysis on a buyer or exporter’s table, these types of scents are far more typical in scenarios where customers are tasting beans in the manner in which they could actually purchase them: The darker the roast, the more probable it is that these dry distillation qualities will be more prominently displayed.

Do you have a favorite perfume from any of these three kinds of scents in particular?

Or are you a little darker, with a smokey Sumatran stripe running through your hair?

Why Does Coffee Sometimes Have a Bad Aroma? – The Coffee Stir

Coffee is a widely consumed beverage around the world. Despite the fact that it comes in a variety of tastes and styles, it may occasionally emit an unpleasant odor. When it comes to coffee, some people have complained that it smells like cat urine, skunk, or ammonia at times. That fragrance is simply the flavor of your coffee bursting forth in full force. The following are some tips for improving the odor of your coffee so that it doesn’t wind up smelling like something completely different!

Why Does Coffee Smell Like Poop?

If your coffee occasionally smells like crap, it’s most likely because the beans have been over-roasted. When coffee is roasted for an excessive amount of time, it develops a strong scent and becomes an oily liquid with a thicker viscosity that can taste bitter or burned. Drinkers of this taste in particular will find themselves smelling like crap as a result of their consumption. Potassium, magnesium, and other minerals may be found in coffee grounds, which is why the odour of excrement can be detected in the beverage.

The darker roasts include a higher concentration of fatty natural oils, which when burned give a disagreeable taste.

There are several options for getting a lighter roast, including purchasing from brands that include light roasting in their mixes (for example, Starbucks’ “Blonde Roast” coffee).

Why Does Coffee Smell Like Cat Pee?

Cat pee is another unpleasant odour that may be associated with coffee. This is the consequence of a chemical interaction that occurs between the coffee beans and the oxygen in the surrounding environment. When organic material, such as coffee grounds or even fruits, is stored in an open container for an extended period of time without any kind of protection from exposure to the elements, oxidative reactions with natural compounds such as phenols develop over time as a result (a type of antioxidant).

This is what has earned this particular kind of coffee the moniker “Coffee Cat Pee.” There are a few things you can take to lessen the possibility that your coffee may smell like cat urine, for example: -Store in an airtight container to prevent spoilage.

-Before brewing the coffee, remove it from its container and allow it to breathe for a few minutes before using it.

Why Does Coffee Smell Like Skunk?

Coffee with a skunky odor is the next scent to be discovered in the rogues’ gallery. It is possible for coffee beans to acquire this fragrance as a result of degradation caused by heat, light, and moisture exposure. This indicates that the coffee was either improperly roasted or that it was not properly preserved after roasting when it was transported to you. In the event that your storage system is up to the task, this should be an uncommon occurrence; but, it is still conceivable. The thiols that give skunk its scent are produced when the coffee beans are cooked, and they are responsible for the odor.

Why Does Coffee Smell Like Ammonia?

Ammonia is quite toxic, and it might be an indication that coffee has been improperly kept. Typically, this is produced by moisture seeping into the coffee beans, which results in the development of an ammonia-like odor. As with the other instances, resolving this issue isn’t too difficult; all you have to do is transfer the coffee from its inefficient storage system to a more efficient storage system immediately thereafter. It is important to note that the chemicals in ammonia are extremely sensitive to the environment, and that a coffee maker that is moist or wet will also produce this type of smell.

Is Bad Coffee Aroma a Symptom of Covid 19?

On a more serious point, terrible coffee fragrance is a problem. It’s possible that you’re suffering from Covid 19 if you’re experiencing loss of taste or smell. If you’ve been noticing a terrible coffee scent, it’s worth getting a Covid test to rule it out. In addition, if you have taken Covid 19, many people have complained of poor coffee odors and a loss of their sense of smell as a side effect.

A metallic or unpleasant aftertaste may also be found in a variety of meals and beverages. Dysgeusia is the scientific term used to describe this occurrence in humans.

How To Keep Coffee Beans Fresh

As we have seen, unwanted coffee odors are primarily caused by improper coffee storage. Coffee beans should be stored in an airtight container away from direct sunlight in order to maintain their freshness. There are several excellent airtight coffee bean containers available for purchase, but the following are the best three in my opinion: The table was unable to be shown.

How Should Coffee Smell?

In this section, we’ve spoken about how coffee can occasionally have an unpleasant fragrance. Coffee has a nice scent more often than not. The simplest way to explain it is that it should be powerful but not overpowering, and you should be able to taste it both with your tongue and your nose. High temperatures are used to roast coffee, which results in the production of aromatic oils, some of which are pleasant to the nose, as well as less desirable aromas such as fruity, corn chip-like flavors, which are sometimes described by tasters as having a woody, musty, or burnt popcorn aroma note.

The brewing method will also have an impact on the taste notes.

We hope that this post has been of use in answering your queries about how coffee should smell!

The Science Behind Why Coffee Smells So Good

The likelihood is that you have coffee coursing through your veins like it’s connected to an IV, as do the vast majority of college students. Has it occurred to you that the reason your favorite beverage smells so nice may be because it is? In accordance with scientific findings, coffee possesses a number of characteristics that make it one of the most enticing odors to humans, even the sleep-deprived college student. So go ahead and take that cup and another shot of espresso because science says it’s possible.

The Science of Smell

Smell has long been considered to be one of the most acutely sensitive senses in humans. What is it about fragrances that makes them so distinct and potent? The olfactory bulb, which is housed in the brain, is the structure that the body uses to record odors. This bulb contains a group of olfactory neurons that are each associated with a particular odor. The shape of molecules flowing through the air and into your nose is frequently related with the smell of a particular scent. Smells can have the same characteristics as wines, such as being “floral” or “earthy,” for example.

What’s in your cup?

Thanks to coffeechemistry.com for the photo! Caffeine is the first and most crucial component in the formula. Due to the release of dopamine, coffee causes your brain to become more awake and attentive and makes you feel more awake and aware. Caffeine’s distinctive bitterness and black color are mostly caused by the presence of citric acid and phenols in the beverage. The aromatic qualities of coffee are attributed to the presence of additional aromatic chemicals. These chemicals are released during the roasting of coffee beans, which is frequently referred to as the most significant step in the coffee manufacturing process.

  1. The following is a recipe for the most perfect cup of coffee on the planet.
  2. The distinctive aroma of coffee encompasses a wide range of appealing smells, including sweet, spicy, fruity, flowery, and smokey.
  3. Phenols, as previously stated, are responsible for the bitterness found in coffee, but they are also responsible for the smokey or earthy aroma that is commonly seen in dark roast coffee.
  4. Additionally, Mercapto has a “spicy” aroma that is frequently associated with curries and may even be found in certain human perspiration, according to the manufacturer.

Last but not least, Hydroxymethylfurfural (HMF) is responsible for the caramel or sweet fragrance that draws the majority of people to consume coffee. Want to know more about the chemistry of coffee? Check out this article. Here is a comprehensive list of all the molecules and aromatic compounds.

A Gene for Caffeine

Animated gif created by ucresearch.tumblr.com Scientists have discovered that your coffee addiction may have a hereditary component, according to their findings. Eight genes have been identified as being associated with increased metabolic rate and a preference for caffeinated drinks. These genes may also have a role in the way coffee affects one’s mood and alertness after consuming the beverage. So the next time you find yourself drawn to the scent of freshly brewed coffee, put it down to your genetics.

Your Coffee Smells

Coffee has a greater variety of scents than wine. In coffee, it is believed that there are approximately 800 unique fragrances that may be detected, however in wine, it is thought that there are only 400 aromas. When coffee aficionados claim to be able to detect a flavor, they are mistaken. Sweet, sour, bitter, and salty are the only tastes that can be detected by the tongue. It is your nose that is responsible for detecting the aromas. When your nose picks up on a fragrance, your brain converts it into a taste in your mouth.

  • Aromas can be detected in two different ways.
  • Second, retro-nasal inhalation is accomplished by inhaling scents from the mouth via the nose.
  • Their next step is to suck the brewed coffee in order to atomize some of the coffee in their nasal passage.
  • When they close their mouths and exhale via their nose, they can smell the scent that is being released.
  • Temperatures of 170 degrees Fahrenheit and above temporarily anesthetize the taste buds, resulting in a reduction in total taste perception.
  • The difference in scent between hot coffee and warm coffee is noticeable and significant.
  • Kona coffees are frequently characterized by fragrances of fruit, spice, chocolate, and floral notes.
  • Coffees can also have unpleasant scents such as vinegar, sour apple, grass, burnt wood, rancid oil, and mildew, amongst other ingredients.

Don’t drink coffee that has a terrible odor since your nose will tell you. Other flavors that your tongue may detect, such as umami, may or may not exist; nonetheless, they do not appear to be present in coffee, at least not to my knowledge.

Those of you who regularly begin your day with a cup of coffee are well aware that the beverage does not taste the same no matter where you go. It doesn’t matter if you brew your own coffee, buy it from a cafe on your way to work, or receive it from the breakroom at work; there are distinct adjectives to describe coffee in each situation. As a result, professional coffee tasters have a large coffee vocabulary, and specialists have a large number of terms to describe this vital beverage; as a result, we have decided to share some of these words with you.

  1. Here are eight of the greatest terms to describe the scent of freshly brewed coffee: 01 CaramellyCaramelly coffees are classified as sugar-browning smells, which means they have a caramel flavor.
  2. If you’ve never smelled caramel before, it has an extremely sweet scent that reminds you of candy or syrup.
  3. “My favorite part of the day is going to Brown’s Coffee House since it gives me the opportunity to inhale all of the delicious aromas.” “My favorite scent is caramelly coffee,” says the author.
  4. Chocolaty Chocolaty coffee may also be found in the sugar-browning group of coffee scents, which is similar to the aroma of chocolate.
  5. The scent is not always similar to the smell of the chocolate bars that you may purchase off the store.
  6. For example, “There’s nothing quite like a strong, chocolaty-smelling cup of coffee to get you up in the morning.” The fragrances of coffee may also be enzymatic, which means they might be herbal, fruity, or floral in nature.
  7. E.g.

04Fragrant Enzymatic coffees, such as fragrant coffees, are classified as such.

One method to express how fragrant your coffee is, if you believe it to be such, is as follows: E.g.

“It reminds me of the spices in my mother’s pantry.” 05 Coffee fragrances with floral or fruity notes come into the same group as enzymatic coffee aromas.

Fruity coffees often have a floral scent, such as coffee flowers or tea roses.

06NuttyNutty coffee is classified as a sugar-browning coffee because it has a distinct aroma that resembles roasted peanuts or walnuts.

For example, “The mild, nutty scent of this cup of coffee is making my mouth water!” Photo by David Disponett used with permission from pexels.

These have a fragrance that is similar to terpenes or to certain medications.

For example, “I wasn’t sold on this brew at first because of the resinous fragrance, but after a few tastes, I found it to be pretty wonderful.” 08SpicySpicy coffee is another type of coffee that falls within the dry distillation group.

It might have a clove or thyme scent to it.

You may demonstrate your knowledge by stating anything along the lines of: “The pungent scent of this brew transports me back to the holidays spent with my grandparents at their cabin in the woods,” for example.

In the context of a professional, acidity refers to the way the coffee feels and tastes on the tongue when consumed.

If you wish, we can also talk about the harmony of a cup of coffee.

The word “bright” refers to an acidity that is robust and well-pronounced, which implies that you can taste all of the tastes quite clearly.

“I really enjoy the acidity of this coffee,” for example.

It isn’t really intriguing, nor is it particularly vivid.

For example, “This brew is a little boring.” Perhaps bottled water or less milk might be used in the future?’ ” Dasha Pats photographed a reshoot.

Nippy acidity is a type of strong acidity.

For example, “This beverage’s sharp acidity and tangy scent give it the advantage over the bright, earthy brew that we drank before.” 13Piquant Generally speaking, coffee with piquant acidity is described as being sharp; it has a pleasant or enticing flavor.


It’s possible that it was cultivated at a high elevation.” In most cases, sour acidity indicates that the coffee was made incorrectly, and it has an unpleasant bitter or pungent flavor.

For example, “I appreciate that you took the time to prepare me a cup of coffee, but the acidity is a little sour and difficult to take.” engin akyurt’s photo on unsplash15 is used with permission.

The tastes and textures are clearly defined, despite the fact that the dish is light.

The flavor, on the other hand, refers to the flavor or impression that the coffee left on your tongue after it is consumed.

Coffee that is bitter will have a strong or pungent flavor.

Using an example, “I’m attempting to reduce my sugar intake, but I don’t think I’ll ever get used to bitter-tasting coffee.” Image courtesy of Adam Jaime on Unsplash.

This may be due to an incorrect bean-to-water ratio, or it may be due to the addition of too much milk to the mix, which can easily drown out the flavor of the coffee bean.

“Could you please make me another cup, possibly with some sugar as well?” In the context of coffee, the phrase “full” describes the amount of liquid in the cup.

You will have to experiment with several different coffees to decide if a coffee is full-bodied or not, and this will depend on your own preference.

In my opinion, the Midnight Brew will be a better choice than the Morning Burst.

19 It is possible that coffee will have a salty flavor as well.

Depending on the kind, it may be astringent, harsh, or even sharp.

Salty beers do not sit well with me.

20 A lot of individuals like sweet coffees since they are easier on the mouth than bitter coffees.

Why Does My Coffee Smell Weird? (11 Aromas Explained)

Is it ever occurred to you that your coffee smells a little bit like something else? As it turns out, you are not alone in your observations. I conducted some preliminary study on the issue of what coffee smells like and came up with some fascinating parallels. Now, I can’t claim that I’ve ever had coffee that smelled like all of the stuff listed below. but I’ve definitely had coffee that smelled like more than a handful of them. Take a look at this list of things that coffee may or may not smell like and see what you think!

11 things people are saying their coffee smells like

The following 11 items are descriptions of what real individuals have said their coffee smells like. I’m not sure how I know this. I just typed a question on Google Autosuggest. If you type “my coffee smells like” into the Google search box, you’ll get several results that are very similar to mine. Regardless, let’s take a closer look at them.

1. Weed

If you’ve ever had the impression that your coffee has a skunky scent to it that reminds you of marijuana, you’re not alone in thinking this. I can’t recall a specific instance in which I had this thinking, but it appears that many others are searching for “why does my coffee smell like cannabis” on Google: “why does my coffee smell like weed?” Now, it’s possible that they just smoked too much cannabis that morning and are now smelling it on themselves, or it’s possible that there is more to this.

These compounds contribute to the “skunky” scent of low-quality cannabis, as well as the aroma of coffee and skunk musk.

2. Urine or cat pee

If you’ve ever had the impression that your coffee has a skunky scent to it that reminds you of marijuana, you’re not alone in your perception. I can’t recall a specific instance in which I had this thinking, but it appears that many others are searching for “why does my coffee smell like cannabis” on Google, which I find amusing. This may be the result of their having used too much cannabis that morning and smelling it on themselves, or it could be a genuine coincidence. This one small fragment of writing came from a Quora member, which I thought was worth sharing.

The scent of low-quality cannabis, as well as the aroma of coffee and skunk musk, can be described as “skunky.” These sulfur-containing molecules are the source of the odor.

3. Fish or tuna

In coffee, I’ve detected this scent previously; it wasn’t very often, but I did detect it once or twice in high-quality dark-roasted coffee from Starbucks. There are a variety of possible explanations for this.

In order to comprehend the process of roasting coffee beans, it is necessary to realize that a chemical reaction takes place. It is possible that the roasted beans will have a fishy odor after they have been toasted. Here are a few possible explanations for why your coffee smells like fish:

  • The outcome of using immature green beans in the roasting process
  • Oxidation that occurs during storage
  • Owing to the hygroscopic nature of coffee beans Storage in an insufficient manner
  • Equipment that is in poor condition

Another interesting fact I’ve learned from numerous internet users is that when they consume coffee, their pee has a strong tuna scent to it. So, if you’ve had a similar experience, you’re not alone. Unfortunately, I do not have a satisfactory explanation for this, and it is possible that you should consult with your doctor about it.

4. Poop or dog poop

I’ve also learned from several internet sources that when individuals drink coffee, their pee has a strong tuna scent to it. It’s important to know that you are not alone if something has happened to you. Unfortunately, I do not have a satisfactory answer for this, and it is possible that you should consult with your doctor about this matter.

5. Skunk

It is possible that the skunky odor is created by the same occurrences as those listed in the previous section. Slightly less than one percent of the weight of a coffee bean contains the chemicalfurfuryl mercaptan, which is comparable to one of the compounds used by skunks in their self-defense spray. As a result, it is possible that minute quantities of this chemical are produced during the roasting or grinding of coffee beans. I’m not sure what that is, but a skunky scent is not unusual for some types of coffee in specific settings, according to my research.

6. Cigarettes

Now, I’ve been a coffee drinker for a long time, many years. I also smoked cigarettes for a far longer period of time than I should have, but I’ve been smoke-free for several years now, thank goodness. I never got the two aromas mixed up in all that time, so I’m not sure what the connection is, if any, between the two scents in this case. Someone who like coffee speculated that the fragrance may simply indicate that their cup of coffee is stale, while another claimed that Robusta coffees smelled like cigarettes.

7. Chocolate

If there is one thing we have learnt thus far, it is that coffee does not necessarily smell like regular coffee. Coffees that smell like chocolate are possible, although they are more likely to have a chocolaty flavor than they smell like. Particularly if it has just been freshly roasted.

8. Burnt popcorn

If there’s one thing we’ve learned so far, it’s that coffee doesn’t necessarily smell like the classic cup of java. Chocolate may also be present in the aroma of some varieties of coffee; nevertheless, the taste of chocolate is more common. Even more so if it’s just been roasted.

9. Rotting meat

However, I did come across something fascinating in regards to the coffee smelling like rotting flesh, which I believe is tied to the pee and dung scents in some way. For those of you who were alive in 2020, you’re undoubtedly aware that one of the more recently identified symptoms of Covid-19 is that your sense of smell can become completely erratic, if not completely absent. Several folks have even stated that their coffee has begun to smell like decaying flesh as of late.

10. Vomit

It seems to me that this is related to the same reasons why coffee could smell like pee, dung, fish or rotten flesh in the first place.

Another possibility is if someone is pregnant, in which case odors and tastes of all types might alter and become difficult to distinguish from what they truly are. According to what I’ve learned, this one isn’t as frequently cited.

11. Soy sauce

It is possible for a light-roasted coffee to have a stronger acidity and a slight salty flavor or fragrance at certain times. A further distinction is that coffees grown in particular countries, such as Kenya or Rwanda, have higher umami qualities, which can have a soy sauce-like flavor.


For some people, coffee might have a peculiar fragrance in addition to smelling like wonderful coffee, which is understandable. Additionally, certain varieties of coffee, as well as specific phases of the production process, might have an off-putting fragrance. At the end of the day, just because your coffee has a weird fragrance doesn’t always imply that your nose is damaged. There’s a good chance that someone else has noticed the same fragrance in their coffee as well.

Enjoying the rich scent of freshly roasted coffee beans is one of the most enjoyable aspects of the coffee-drinking experience. But image opening a bag, taking a deep breath, and smelling.fish (more specifically, tuna.) Even worse, some people mistakenly believe that this stench is cat pee! I understand that the phrases fish, cat urine, and coffee should never be paired with one another in the first place. That would be enough to permanently damage the minds of most coffee enthusiasts. If something like this has occurred to you previously, you are not alone.

  1. Of course, if the beans are moldy or rotten, they should be thrown out as soon as they are discovered.
  2. I recall the first time I was greeted by this unexpected scent when sampling a high-end brand of Kona coffee.
  3. For those who are unfamiliar with Kona coffee, it is regarded an extremely exotic and expensive coffee, thus it was reasonable to expect high standards.
  4. As soon as the fragrance touched my nostrils, I knew there was something seriously wrong with the coffee and was prepared to quarantine what I believed to be rotten coffee beans.
  5. Once the coffee was made, it tasted absolutely delicious, with not even the faintest trace of fishiness.

Why Coffee Beans Smell Like Fish

In coffee beans, the fishy scent that is produced as a result of chemical reactions that take place during the roasting process causes them to smell. Dark roasts, which have naturally been subjected to high temperatures for extended periods of time, are particularly prone to smelling fishy. Some have theorized that the presence of Ethylmethylamine, which has a strong ammoniacal and fishy stench, might be the cause of the problem. Because each batch of coffee beans is unique, the exact reasons for why your individual coffee beans smell like fish will change from batch to batch.

However, the point is that it is typically not a source of concern.

While it may go against every olfactory sensitivity you possess, the fact is that you are not alone.

In addition, if your Keurig or coffee pod machine is making you smell like fish, you might try checking for mildew and descaling your equipment. For additional information, please see our article on decaling your Keurig.

Does You Coffee Smell Rancid?

I’ve seen a few messages on the internet regarding ground coffee smelling like fish, so I decided to look into it. More particularly, freshly ground darkroasted coffee that has a fishy scent to it. When examining why your ground coffee has a fishy odor, here are a few options that can be useful to consider: 1.

When was the last time you cleaned your grinder?

It is possible that oils have accumulated within your grinder, which is generating the rotten, fishy smell, depending on the type of coffee you purchase (light roast vs medium roast vs dark roast).

When was the last time you cleaned your brewing equipment?

You might be surprised to learn that your kettle and brewing equipment (cone brewer, coffee maker, etc.) require thorough cleaning at least once a year. Organic and inorganic elements (such as minerals and micro-plant matter) might accumulate on your brewing equipment over time, and this is normal. The use of a reusable coffee filter is extremely important in this situation. The majority of the time, they are not causing a rotten odor, but they might undoubtedly be contributing to the problem of your coffee smelling sour or rancid.

How old is your coffee?

Most roasters include a roast date on their coffee bags so that customers may tell how old their coffee is after they purchase it. The fact is, however, that despite the fact that there is an abundance of information on how long coffee has a shelf life, there is no conclusive answer. In an airtight container out of the sun at room temperature, coffee can last for weeks, even months before losing its flavor due to oxidation and degradation. Dark roasted coffee that has just been pulled from the roaster is not yet greasy.

These oils diminish and finally evaporate after a few weeks (or even months) of exposure to the environment.

Have you ever noticed how black it is, but there are never any signs of oil on the surface of the water?

Again, how old is your coffee?

Does ground coffee have a fishy scent to it? Another thing to keep in mind about old coffee (that is, roasted coffee that has been sitting about for several months) is that the oils frequently go rancid and generate a scent that is akin to that of fish or seawater. This is due to the oxidation that has occurred as a result of the coffee’s exposure to oxygen, and the oils have become sour or rancid. This isn’t true of every dark roasted coffee, but it does happen from time to time.

How’s your water?

It is critical to use high-quality water for brewing. Drinking coffee made with tap and/or filtered water will produce the best-tasting results depending on your location. The Sierra Nevadas and the Rocky Mountain Range, however, are likely to have water coming from a local spring or well, and it’s likely that this water is much better for brewing your coffee because it contains organic and inorganic matter that is essential for A) proper human hydration and B) delicious coffee flavor.

Test both your filtered water and your tap water to see which performs better. Both should be boiled separately and let to cool to room temperature before serving. Once the water has cooled, compare the flavors of the two waters to discover which one you like.
