According to its size, the grinding methods of coffee beans can be divided into three types: rough grinding, medium grinding and fine grinding. Use the appropriate grinding method according to the coffee utensils.
There is also medium fine grinding or very fine grinding (powdered coffee powder) which is finer than fine grinding. The timing of grinding coffee beans is before brewing coffee, only the need for grinding is the top grade. After the coffee bean is ground into powder, its surface area increases and absorbs moisture, which is easy to oxidize. In short, with the passage of time, coffee powder also plays a role of deterioration to damage the flavor. And after the ground coffee beans are placed, the carbon dioxide retained inside the beans will be lost together with the aroma. In this way, when the coffee powder is extracted and filtered, the coffee powder should be expanded without expansion, and you can't make delicious coffee anyway. The secret is to consider grinding and homework consistently, so brewing coffee is the most delicious and mellow.

The grinding of coffee beans is exquisite
1, the particle size is uniform: the size of the ground particles is uneven, and the taste of the brewed coffee will be inconsistent. If the grinding particles are ultra-fine, the more coffee ingredients can be extracted, and the thicker the particles will be, the fewer ingredients will be extracted. In order not to destroy the original aroma of coffee, care should be taken when grinding to make sure that the particles are uniform.
2, avoid friction heat generation: high-speed grinding coffee beans will produce heat due to friction, this heat will make coffee powder deteriorate or make coffee aroma lost, manual grinder is especially easy to produce heat, we should pay attention to slow grinding.
3. Remove fine powder: some fine powder will be produced when grinding coffee beans, such as tannin and other bitter substances will be released when mixed in it, and fine powder will be produced more when using electric grinder. Some electric grinders have the function of automatically removing fine powder, which can usually be removed manually, because fine powder is lighter than normal coffee particles. As long as the ground powder is shaken and blown, it can be removed.

3. Grinding with a rolling pin: using a rolling pin is similar to using a hammer, wrapped in a fresh bag or in parchment and thin towels, crush the coffee beans with enough force and keep rolling back and forth until the coffee bean powder reaches the thickness you need. if you don't have a rolling pin, a strong food bottle or can can be used as a grinding tool.
