under-extracted coffee

Insufficient extraction means that the coffee powder is not enough, and there are many residual substances in the coffee powder that can increase the flavor of the cup of insufficient extraction. Imagine a cup of short-lived espresso, known as a premium espresso ristretto, with a sour smell, a lack of sweetness, a strange salty taste and a disappointingly short aftertaste. These four characteristics are obvious signs of underextraction, so let's take a closer look at the phenomenon of underextraction.

prickly sour

The acidity of coffee can be tricky, especially if the coffee's acidity is expected.

Definition of prickly acidity as a negative taste. The tongue will quickly and strongly feel the sour taste, which will cause an immediate physiological reaction. You may wrinkle your lips or have an electric shock or sharp feeling on both sides of your tongue. Sour taste can be unpleasant and spoil your palate, and it's not the taste you want.

When it comes to acid, it can be good or bad, and acid is more like a flavor than a good word. For example,"The acidity of coffee is pleasant," or "The acidity of this coffee is high," is logical. Acid and sour/juicy/acid bright/irritating acid These can be linked, you can write an article about acid, but this article is about extraction. Back to business.

lack of sweetness

The most important thing about coffee flavor is sweetness. Sweet is the best. Have you ever heard someone complain like that?" This coffee is too sweet!" Let's think about it, I'm pretty sure we're all after the sweetness of coffee. Sweet taste is like the Holy Grail that is very hard to find, and once found, there are amazing rewards! Insufficient extraction is not sweet, and far apart. Lack of extraction can show post-coffee dissatisfaction, giving people the feeling of emptiness I want more coffee. It is worth mentioning that the lack of sweetness can highlight the sour taste of coffee beans and make people feel the lack of extraction more obviously.
