The main characteristics of coffee over-extraction
Excessive extraction means that you put too much flavor in the coffee beans into the coffee. The same company will emphasize the taste of coffee. Imagine you are drinking a cup of hand-held coffee that has been extracted with powder for 10 points. I believe everyone has had the same kind of feeling. This kind of coffee is bitter and tastes dry and empty.
These three points are the main features of over-extracted coffee:
1. Endure hardship.
We all know that coffee is bitter, but over-extracted coffee is very bitter. I don't want to drink this bitter wine unless I'm drinking Campbell's Campari! The bitterness comes mainly from caffeine and other chemicals. Deep-roasted coffee beans contain more of these bitter substances (except caffeine).
two。 The taste is dry and crisp
Being dry is one of the worst feelings. It's not the taste, it's the taste. It gives people a strong sense of resistance and stays on the tongue for a long time. This feeling can be described as sweet, and the feeling of coffee is caused by the bitter degradation product, dicaffeoylquinic acid, produced by the protogenic acid contained in coffee during roasting.
3. The taste is stiff.
The over-extracted coffee is very stiff in the mouth and has no vitality, just like taking away all the life of the coffee, leaving only a zombie. This kind of coffee is dry, empty, rigid, lack of sweetness and flavor.
