Why Your Coffee is Bitter

Why Your Coffee is Bitter

Posted by Eddie on 6th May 2019

You've spent good money of fresh ground FTO coffee, a burr grinder, and a decent brewer...but your coffee is bitter. What gives? Here are two explanations, and ways to fix the bitterness: 

  1. Usually this is due to the incorrect coffee-water ratio. If you brew your coffee and it’s bitter, try putting a little more water in the cup, or lower the coffee-water ration next time you brew. This ratio will be different depending on the brew method.
  2. This can also be due to selecting the right grind size for your brewing method. For example, if you are trying to use a course coffee bean grind while brewing espresso or Aeropress, which uses a fine or medium-fine grind, then the coffee will be bitter.

A general guideline is called the "Golden Ratio" - one to two tablespoons of ground coffee for every six ounces of water. This can be adjusted to suit individual taste preferences.
