In fact, the thickness of the coffee powder has a great influence on a cup of coffee. For example, for brewing coffee, if the ground is too fine, the surface of the water and the coffee powder will have too much contact, and it is easy to extract too many impurities and bitterness. If it is too thick and the gouache contact is not enough, the aroma of coffee cannot be brewed. Therefore, it is very important to adjust the grinding degree that is more suitable according to the brewing equipment and the length of the brewing time.
