How to Grind Coffee Beans Best

The ideal time to grind coffee is before brewing. Because the ground coffee is easy to oxidize and lose its aroma, especially if it is not properly stored, the coffee powder is easy to change the taste, and it is naturally impossible to brew mellow coffee. Next, the editor will tell you how to grind coffee beans best.

1. The principle of grinding
1. The grinding degree suitable for the brewing method should be selected;
2. The temperature generated during grinding should be low;
3. The powder after grinding should be uniform;
4. Grind before brewing.

No matter what kind of grinder you use, it will generate friction and heat during operation. Most of the high-quality substances are highly volatile, and the heat of grinding will increase the speed of volatilization, so that the aroma of coffee will be lost in the air.

After the coffee beans are ground, the cell wall will completely disintegrate. At this time, the area in contact with the air will increase a lot, the speed 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 better to buy coffee beans, grind them before drinking, and brew them as soon as they are finished. Before the invention of the grinder, humans used stone pestles and bowls to grind coffee beans.

2. Grinding method
The grinding method of coffee beans can be divided into three types: coarse grinding, medium grinding and fine grinding according to their size. Use the appropriate grinding method according to different coffee utensils. There are also medium-fine grinds or finer than fine grinds and fine grinds (powdered coffee powder).

1. Fine grind (Fine grind): The particles are fine, as big as granulated sugar.
2. Medium grind (Medium grind): The particles are as big as the mixture of granulated sugar and coarse white sugar.
3. Regular grind: The particles are coarse, the size of coarse white sugar.

3. The Secret of Grinding
The grinding tool for coffee beans is a grinder. There are three types of grinders:
(1) Manual rotary grinder for household use. It is suitable for leisure people with small demand, large grain size and plenty of time.
(2) An electric grinder for household use. It can grind coffee powder of various particle sizes, and can grind 6 servings at a time.
(3) Professional electric grinder. For commercial use, it can grind about a pound of coffee powder at a time.

The most important thing to pay attention to when grinding coffee beans is the following two points:
(1) Reduce grinding heat. The heat of the grind will cause the coffee aroma to escape prematurely.
(2) The particle size is uniform. Uneven particle size will result in unpredictable brewing times.

So if you use a home-style manual grinder, you should rotate it gently to avoid frictional heat as much as possible. To sum up, if you consider the quality of grinding beans, the amount of grinding beans, the time of use and convenience, using an electric grinder for household use will be the best choice.
