Cách sử dụng
The word 'ferment' refers to a process where bacteria, yeast or other microorganisms break down sugar into alcohol or acid. It is usually used in the context of making beer, wine, or bread. To ferment something means to let it sit for a while in a warm environment, so that the microorganisms can do their job. For example, you might hear someone say "I'm going to ferment some cabbage to make sauerkraut" or "The dough needs to ferment for a few hours before baking".
