In the process of making hand-brewed coffee, grinding coffee powder is a very important step. The more uniform the coffee powder is, the more you can brew a good cup of coffee. Generally speaking, the recommended degree of grinding of hand-brewed coffee is to pass 70% of the degree of grinding of the 20mm filter, which is called the cup test degree of grinding and is certified in the industry.

In the selection of bean grinding machine, we should choose the bean grinder with high grinding efficiency, less calorific value, uniform grinding as far as possible, less fine powder and less residual powder.

In the process of grinding, there will be friction and heat energy, which will accelerate the volatilization of aromatic substances in coffee beans, so the aroma of coffee extracted into the cup will be reduced, and uneven grinding will lead to excessive extraction of some coffee powder. insufficient extraction of some coffee powder is affecting the flavor of coffee.
