. Points for attention in grinding coffee beans

(1) the friction heat should be suppressed to a minimum (because the heat will volatilize the aromatic components).

(2) whether the size of the particles is uniform or not (if the particles are uneven, the concentration will be uneven).

Taking this into consideration, if you grind coffee beans at home, you should rotate them gently and make sure that they do not produce friction heat as much as possible; of course, electric grinding will be a good choice.

The skill of grinding coffee

Rough grinding is suitable for filter coffee pot, the so-called filter is the traditional brewing method in the United States. Medium grinding is suitable for brewing methods such as follicle type, flannel net type, siphon pot and so on. Fine grinding is suitable for coffee distiller (already called ice drop coffee maker). Very fine grinding is suitable for brewing espresso.

Grinding machines also have a great impact on coffee, experts say, try not to use a propeller-type bean grinder, because it is not grinding beans, but chopping beans. Should look for that kind of jagged bean grinder, this kind of machine grinds the beans, the thickness is uniform, in the grinding process, will not burn the beans. The aroma of coffee will not lie, whether a cup of coffee is fresh and mellow, in the grinding, has already leaked the "first opportunity". Those who know how to taste coffee must understand the importance of grinding to preserve the aroma of coffee!

The corresponding relationship between the grinding degree of coffee powder and various brewing methods, on the whole, the production time is longer, that is, the degree of grinding required by the brewing method of coffee powder with longer contact time with water is usually thicker, the reason is that the finer the grinding degree of coffee powder is, the larger the contact area between coffee powder and water is, and too long brewing time will lead to excessive extraction of oil and aromatic substances in coffee, making coffee taste bitter. Coffee powder with a finer degree of grinding should be brewed in a way that takes a shorter time to make, that is, a shorter contact time between coffee powder and water. Contrary to the previous situation, if the coffee powder is too thick, short brewing time can not fully extract the essence of coffee, coffee taste thin, plain taste. What needs extra attention is that whether the grinding degree of coffee powder is constant or not will directly affect the final taste and quality of coffee.
