Why Does Ground Coffee Smell Like Cat’s Urine?
More often, coffee has a pleasant and wonderful aroma.
It is strong but not too overwhelming where you can taste it with your mouth as well as nose.
Coffee is roasted at a high temperature.
This process creates aromatic oils and even has some pleasant odors.
Sometimes, certain less desirable aroma could be created during the coffee beans roasting process.
This might give a pungent, woody or musty smell to the coffee beans.
Therefore, the improper roasting procedure is also one of the contributing factors for coffee smelling like cat’s urine.
If the process of roasting of the beans is not followed properly, then it could also affect the taste along with smell of your coffee.
Similarly, the brewing process too has an effect on it and leads to the alteration of the flavor notes.
But, it is usually not the factor that causes coffee smelling like cat urine.
Improper storage of the coffee grounds can also lead to weird smell of the beans.
The organic material, such as coffee grounds are in most cases stored in an open container for too long without any kind of protection.
This leads to the over exposure of the coffee grounds to air and oxygen for long period.
This over exposure causes oxidative reactions that occur over time with natural substances like antioxidants.
This causes the ground coffee to have a sour and high-acid taste and unpleasant aroma like cat’s pee.

Also, check whether your coffee has a moldy or lousy structure.
It may have been spoiled if you see lumps in the beans and experience foul smell.

Add some baking soda directly to the stains and let it sit for 10-15 minutes.
After that, wash it with cold water again.

Why Does Coffee Smell like Poop or Ammonia?
If your coffee smells like poop then this is likely due to over-roasted coffee beans.
When coffee beans are roasted for much longer period, then they usually produce a strong aroma.
Along with the strong aroma, it also produces oily liquid with a thicker consistency that can taste bitter and somewhat burnt.
This flavor in particular may cause your coffee to smell like poop or ammonia.
One more reason for such type of foul smell can be attributed to the basic elements of coffee grounds.
Coffee grounds mainly contain substances such as potassium, magnesium and other minerals.
Coffee beans are roasted at high temperatures in order to activate the natural oils which produce an unpleasant flavor when burnt or over roasted.
However, the world’s most expensive coffee is made out of poop.
It is made from coffee beans that are partially digested and then pooped out by civet, a cat-like animal.
Their digestive enzymes change the structure of proteins in the coffee beans, which removes some amount of acidity from the coffee.
The cherries are fermented as they pass through a civets’
And after being defecated with other fecal matter, they are finally collected.
The taste of Kopi Luwak coffee varies with the type and origin of the excreted beans, processing, roasting, aging and brewing.
The ability of the civet to select its berries, and other aspects of the civet’s diet and health, like stress levels, may also influence the processing and the taste of the coffee.
We now know the fact that this coffee, called as Kopi Luwak is made out of civet’s poop.
But it has earthy and musty flavors with hints of caramel and chocolate and it has a pleasant aroma.
This is due to the internal fermentation by digestive enzymes inside the body of the animal.
On the other hand, ammonia is very potent and it can be a sign of coffee that has been stored wrongly.
This is usually caused by moisture getting into the coffee beans and causing an ammonia-like unpleasant aroma to develop.
In such a situation, you just have to alter the way you store your coffee beans at home.
The chemicals present in ammonia are very sensitive to air and if your coffee maker is moist or wet then it’s likely to produce this kind of smell.
So, keep the coffee maker and your containers clean and dry.
You can purchase coffee that is lightly or medium roasted.
The darker roasted have more oil content and may give an unpleasant odor.
