Recently, there is a coffee machine and a mill, and it is even easy to enjoy coffee bought in the state of beans. Coffee is deep, and the flavor varies greatly during a grinding process. Here, I will introduce how to grind coffee.

What is grinding?

Grinding roasted coffee beans is called "grinding". The size (particle size) of the powder will greatly affect the filtration speed and flavor. Generally speaking, the finer the grain of ground beans, the larger the surface area, the more coffee ingredients are extracted, and the bitterness becomes a unique flavor.

If you grind it roughly, you will finish some coffee, from light coffee to strong coffee, with a more distinctive flavor.

Keep the main points in mind when grinding

Recently, more and more people grind their own coffee beans at home, but when grinding beans, we try not to make the grinding uneven and mix fine parts with rough parts. Due to the uneven particle size after grinding, it may lead to uneven extraction and can not fully extract the original flavor.

In addition, don't forget to change the grinding method according to the equipment to be extracted.

About the coffee mill

Grinding instruments are called bean grinders, and they are divided into manual, electric things to do. According to the different teeth of crushed beans, they can be divided into three types: cutting type, grinding type (grinding type) and propeller type.
