Acidity and Bitterness in Coffee

Why Coffee Tastes Bitter?

Throughout roasting, mainly from the first cracking and at bean temperatures about 200 °C, chlorogenic acids are transformed into the related lactones through the breaking of one water molecule. This is the critical chemical stage that turns the acidic chlorogenic acids into the bitter taste.

The Color of A More Bitter Coffee

Temperature of Bitter Coffee

Chlorogenic acid and lactones experience more oxidation at darker roasts and higher bean temperatures over 210 – 220 °C, resulting in a separation of quinic acid and, after a few more stages, the metallic, remaining bitter phenylindoles. These chemicals are undesirable because they make our cup of coffee taste strongly bitter.


Extracting Bitterness during Coffee Brewing

Let’s see some steps for preparation of Coffee!

Grinding of Coffee

With the grinding of the beans, the grind size, has a major effect on the bitter and sour taste of the coffee. A fine ground provides a larger processing surface for water to flow through. Acidic compounds take over when coffee is ground very roughly chopped.

Brewing Procedure

The longer coffee is extracted, the more of the previously described bitter compounds are collected into the brew, notably the extremely bitter-tasting phenylindoles.

Temperature of the Water

The temperature of the water also has an effect on the flavour profile. Higher water temperatures produce a bitterer cup than lower temperatures. It is advised that the water temperature is maintained between 90 and 95 °C. Since too low a temperature will result in a flat flavor and taste blend.


How to make Coffee less Bitter?

  1. Prefer Light or Medium Roasted Beans

  4. The bitter taste cannot be “removed,” but it can be balanced by applying more salt, sugar, or honey.​
