Over Extraction — When you pull out too much stuff from the grounds, those crisp acids fade away, the sugars hide, and all the good flavors basically begin to disappear. The reason?
Those late-extraction bitter compounds start to drown everything out to produce a dull, lifeless, and bitter brew. Your coffee is over extracted.
You pulled too much stuff from the beans, so you need to extract less stuff next time you brew. Here are a few ways you can do that remember, just one at a time : Brew for less time to stop the extraction earlier Use more coarse grounds to slow down the overall extraction speed Read: How To Taste Coffee: Bitterness Your coffee beans are roasted too dark. Really dark roasts—like Vienna, Italian, and French roasts—are always more bitter than they need to be.
The reason is that, at such high roasting temperatures, a whole slew of chemicals break down into bitter compounds. Your coffee beans are low-grade or robusta. Beans that are poorly grown, carelessly processed, or of the robusta species are bound to be far more bitter that well-grown beans. Next time you brew, try one of these things: Brew for more time to give the coffee a little more time to extract Use finer coffee grounds to speed up the overall extraction speed Read: How To Taste Coffee: Acidity Your coffee beans are roasted too light.
Many people, when they taste specialty coffee for the first time, find it to be too sour. Not all over extracted is really bitter. Those late-extracting bitter compounds and the early-extracting acids just cancel each other out to create a flat flavor with no real distinct features. Try extracting less to see if this is really the issue. Your water quality is bad for brewing.
More often than not, the issue is way too many minerals. Try using filtered water or bottled water and see if the flavor improves to determine if this is really the problem. Your gear is dirty. Eventually, the flavors imparted are just bland and uninteresting—and they overpower any good flavors in the coffee. Give you gear a good cleaning to see if old gunk was hurting your coffee. Your coffee grounds are inconsistent sizes. Some grounds brew real fast and get bitter just as larger grounds are exiting the acidic phase.
This creates a unbalanced flavor that often seems monotoned, but sometimes it seems bitter and sour at the same time. Your beans are low-grade or stale. For the best accuracy, we have kept the descriptions as direct quotes from the respective listing pages.
