Ground coffee beans basic knowledge of coffee products

Because coffee beans are made up of tiny fibrous cells, during the grinding process, the fibrous cells are cut open and the flavors of coffee oil and mellow are released at the same time. Therefore, if you want to make a cup of mellow and delicious coffee, the grinding process is very important.

In the process of grinding, the first thing to pay attention to is that the size of the ground particles should be the same, so that each coffee powder can release ingredients evenly during brewing, and achieve the effect of uniform coffee concentration. Secondly, if you use a manual grinder to grind coffee beans, you should rotate gently to avoid friction heat. If you use an electric grinder, you should pay attention to the selection of materials and structures with lower friction heat. The thickness of the mill mainly depends on the brewing method and time. Basically, the shorter the brewing time is, the more detailed the grinding particles should be. Because the smaller the particles, the larger the area of contact with hot water, so the shorter the time to brew.
