How to choose the coffee grinder is the key to make good coffee.

The grinder is more important than the coffee machine, and players recommend a "sawtooth grinder" because it can grind a uniform coffee powder quickly and steadily. When you choose to buy a grinder, you should pay attention to its power, usually between 70 watts and 150 watts, the higher the better, the higher the power, the faster the grinding speed, and the shorter time the coffee powder stays in the sawtooth, so it can grind the coffee powder at low temperature. The fineness of the ground coffee powder should also be uniform to ensure that the extraction can be uniform in order to make a good coffee.
