Good coffee starts with grinding

To get a good cup of coffee, in addition to the quality of coffee beans, the grinding of coffee is undoubtedly decisive. The best time to grind coffee is before brewing. Because ground coffee is easy to oxidize and lose its aroma, especially if it is not properly stored, the coffee powder is easy to change its taste, and naturally it is impossible to brew a mellow coffee.

Tips for grinding coffee beans

The tool for grinding coffee beans is a grinder. There are many types of grinders, from manual grinders for home use to large electric grinders for business use. Home grinders can also be used as decorations, but if there are many people who need to grind at the same time, electric grinders are more convenient.

According to the structure of the grinder, there are grinders that use vertical and horizontal grooves to cut coffee beans while grinding, and grinders that use molars to crush the coffee. Each has its own strengths, and for business use, the electric type that tends to be mass-produced is the mainstream.

However, the most important things to note when grinding coffee beans are the following two points:

① Suppress frictional heat to the minimum. (Heat will cause the aromatic components to fly away)

② Whether the size of the grains is uniform. (If the grains are uneven, the concentration of the brewed coffee will be uneven)

With this in mind, if you are using a household grinder, if it is a manual type, you should rotate it gently, and be careful not to generate frictional heat as much as possible.

How to use the grinder

There are two types of grinders for home use: manual and electric. Manual grinders are more convenient for a small group of people, while electric grinders are more convenient for large quantities. At the same time, the grinding method (particle size) is determined by the aerator.

When using a manual grinder, be careful not to generate friction heat alone. Also, be careful to see if there are other things mixed in.

Check whether the ground coffee beans are uniform in size. (If the particles are uneven, it may be due to the performance of the grinder or uneven coffee roasting.)
