The grinding method of coffee grinding should include the following four basic principles
1. The degree of grinding suitable for brewing and cooking should be selected.
2. The temperature of cattle produced during grinding should be low.
3. The powder particles after grinding should be uniform.
4. Grind before cooking.
No matter what kind of grinder is used, it is bound to generate heat by friction in operation. Most of the fine substances are highly volatile, the heat of grinding will increase the speed of volatilization, and mellow is lost in the air.
After the coffee bean is ground, the cell wall will completely disintegrate, the area of contact with air will increase a lot, the rate of oxidation and deterioration will become faster, and the coffee will lose its flavor within 30 seconds to 2 minutes. Therefore, it is recommended not to buy coffee powder, it is best to buy coffee beans, grinding before drinking, grinding should be brewed as soon as possible.
Before the invention of the bean grinder, people used stone pestles and bowls to grind coffee beans. A doctor once experimented with this ancient tool and compared it with a modern bean grinder. It is said that the coffee powder made from pestles and stone bowls is the most mellow.
According to logical reasoning, the pestle cracked the coffee bean naturally by impact, which should not destroy the cell wall and retain the excellent substance of coffee. However, in modern life, it is almost impossible for people to use pestles and stone bowls to grind coffee beans, so it is particularly important to choose a good bean grinder.
