7 Reasons Your Coffee Is Bitter & How to Fix It

Updated on:

Coffee is one of the most loved beverages in the world, about 400 billion cups are consumed each year. However, all coffee does not taste the same there is one common complaint among coffee drinkers which is the bitterness of the coffee. Some people may enjoy a bitter taste in their coffee, others like us find it unpleasant and can even lead to digestive discomfort. Here, we will discuss 7 possible reasons why your coffee is bitter and provide solutions on how to fix it for the better.

Reason 1: Low-quality Beans

The quality of the beans being used to make your coffee plays a vital role in its taste. Low-quality beans are often mass-produced and harvested before they are fully ripe, therefore they are cheaper, which leads to an unbalanced flavor profile with a strong bitterness. To avoid the bitterness in the coffee, always opt for high-quality and premium coffee beans that are ethically sourced and freshly roasted.

Reason 2: Poor Roasting Technique

Coffee roasting is a form of art, and if not done properly, it can result in a bitter-tasting coffee. During the roasting process, sugars and acids in the beans caramelize to create a balanced flavor profile. But, if the beans are roasted for too long or at too high of a temperature, they can become burnt thus developing a bitter taste. To resolve this issue, make sure to buy your coffee from reputable roasters that use proper techniques.

Reason 3: Improper Brewing Methods

The method used to brew coffee is also one of the factors affecting the bitterness of the coffee. The Ideal method for brewing a best-tasting coffee is the ideal temperature of coffee. If the water is too hot or the brewing time is too long, it can extract bitter compounds from the beans. Using a coffee-to-water ratio of 1:18 (1 gram of coffee for every 18 grams of water) and brewing with water at around 195-205°F (90-96°C) can help prevent over-extraction and result in a smoother, less bitter cup.

Reason 4: Stale Coffee Beans

Just like any other food, coffee beans can go stale over time. As they age, they lose their aromatic oils and become more and more bitter. To ensure your coffee is always fresh, buy smaller quantities of beans and store them in an airtight container away from direct sunlight.

Reason 5: Dirty Equipment

If you’re using a coffee maker or French press to brew coffee it’s essential to keep them clean. Old coffee oils and residue can build up in the equipment after frequent brewing, leading to a bitter taste in your brew. Regularly cleaning your equipment with hot water and soap can help prevent this issue.

Reason 6: Hard Water

The quality of the water used to brew your coffee can also affect its taste. Hard water, which contains high levels of minerals like calcium and magnesium, can result in a harsh and bitter flavor in the coffee. Using filtered or distilled water can help improve the taste of your brewed coffee.

Reason 7: Personal Preference

Well lastly, it’s important to remember that the taste of coffee is subjective. Some people may simply prefer a stronger, more bitter cup of coffee. If that’s the case, then there’s no need to fix anything. However, if you find your coffee consistently bitter and unpleasant, it may be time to experiment with different brewing methods or try a lighter roast version of the coffee beans.


Several factors can contribute to a bitter taste in the coffee. By understanding these reasons and implementing the suggested solutions, you can enjoy a consistently delicious cup of coffee without any bitterness.
