How do I use the coffee grinder? How to choose between thick and thin

To adjust the thickness of the hand-grinder coffee machine, if you take it, it should be at the top, there is a spring on top of a nut that can be rotated, and you can see that the direction of spring compression after rotation is the fine direction and the opposite direction is the thick direction.

Notes on making coffee:

1. Brewing coffee has a precise requirement for water temperature, that is, the water temperature should be 92 ~ 96 degrees. If the water temperature is too high, the coffee will be a cup of scorched bitter water, because the temperature above 96 degrees can destroy the oil in the coffee and taste bitter and astringent.

2. Use different coffee machines to make coffee with different thicknesses of coffee powder. For example, mocha coffee machines need finer coffee powder.

3. The quality of brewed coffee is very important, even if it contains a small amount of chlorine, iron or other mineral impurities, it will affect the purity of coffee. It is best to brew coffee with filtered water or cold water that has been in full bloom for a while.

4. Coffee should be drunk within 30 minutes after brewing. Coffee that is too long will become bitter and lose its original taste.
