How to make a good cup of coffee

I have seen many people who would rather spend a lot of money on other coffee-making utensils than configure a better grinder. In fact, the size, shape and uniformity of the ground particles will directly affect the extraction rate of coffee and further affect the quality of the whole cup of coffee. To some extent, the grinder is even more important than the coffee maker itself. If the equipment is not good, we can make up for the defects of the equipment through constant practice and skillful techniques, while the quality of the grinder is not high, but it is powerless through practice. So when buying coffee utensils, I recommend that you spend at least 25% of your budget on the grinder, or even 50%.

A good coffee grinder is mainly reflected in the following aspects:

The uniformity of grinding is the most important thing to judge the quality of the grinder. uneven grinding will cause uneven extraction in the follow-up, often some parts of coffee powder have not been fully extracted, while some parts have been excessively extracted. finally, the whole cup of coffee has a bad smell. One of the most common problems is that fine powder will be produced during rough grinding, resulting in bitter coffee. Although there will be fine powder phenomenon in even the best grinder, the phenomenon of fine powder in some low-end bean grinders will be especially obvious.

The heat generated during grinding as mentioned in the previous article, the aromatic substances in coffee powder are very volatile, and the heat during grinding will accelerate this volatilization. A good grinder can control the heat within a certain range by reasonable torque. However, if people drink their own coffee at home, they only grind a small amount of beans, and the effect of fever is negligible.

Needless to say about the grinding speed, the more time-saving and labor-saving, the better. However, it should be noted that some low-end grinders simply increase the speed to improve efficiency, which will cause a large amount of heat as mentioned in the second point. A good bean grinder generally achieves the balance of heat production and efficiency through low speed and high torque.
