Awareness of the knowledge of the grinding degree of espresso Espresso production

I talked about the steps of pressing powder in the process of making Espresso and the strength of pressing powder, and mentioned a little about the factors that affect the strength of pressing powder, one of which is the degree of grinding of coffee powder. Grinding refers to the process of grinding coffee beans into the coffee powder used in making coffee by using a bean grinder (or manual grinding apparatus), and the degree of grinding refers to the thickness of the coffee powder.
