The Grinding degree of Coffee beans Coffee Grinding skills

Coffee contains a variety of ingredients, extraction does not extract all of these ingredients. Generally speaking, in the case of a certain amount of powder, the extraction amount of soluble components is related to the thickness of grinding and the extraction time. The finer the grinding and the longer the extraction time, the more substances will be extracted. And vice versa. When making a coffee, choosing the appropriate degree of grinding of the extraction method is the foundation of the flavor of this cup of coffee. Anyway, for the same bean, the finer the grinding degree, the stronger the bitterness, the thicker the grinding degree, the weaker the bitterness. Generally speaking, the degree of grinding of coffee is divided into fineness grinding, medium fineness grinding, medium roughness grinding and roughness grinding.

Among them, the brewing methods suitable for fineness grinding are: Turkish copper pot, mocha pot and consciousness espresso machine. The brewing methods suitable for moderate grinding are: filter paper dripping method, flange dripping method, air stopper. Suitable for roughness grinding are: dripping coffee machine and dripping kettle. Of course, this has to be adjusted according to individual taste. Sometimes it's all personal and can't be used as a law. Sometimes I see that some coffee shops will grind the coffee very finely, of course, this can reduce the consumption of coffee beans to control the cost, but the concentrated oil is dark brown, it is extremely irritating to drink, and it is difficult to swallow. In this way, it has a great impact on the quality of coffee, and the loss outweighs the gain. The final mastery depends on the individual, depending on which degree of grinding you like.
