How to use the hand coffee bean grinder? which is good?

Coffee beans, the dark brown beans seem ordinary, but they have a lot of knowledge at all stages. For a coffee cook and drinker, it is enough to have a general understanding of the professional knowledge of the cultivation, production and roasting of coffee beans, and the production can be left to the coffee merchants. After all, this is an era of paying attention to the division of labor. However, it is the user's responsibility to grind and make coffee, and we must have a clear understanding.

When grinding beans, the size of the powder depends on the way it is cooked. The shorter the cooking time, the finer the ground powder; the longer the cooking time, the thicker the ground powder. Sixth, in terms of the actual way of cooking, it takes a very short time for the ESPRESSO machine to make coffee, so the grinding is the finest, and the coffee powder is as fine as flour; it takes more than a minute to cook coffee in the "plug wind" way, and the coffee powder belongs to medium-sized grinding; American filter coffee takes a long time to make, so the coffee powder is the thickest, one by one like Beijing grains on a shell beach. Grinding coffee powder with appropriate thickness is very important for making a good cup of coffee, because the extraction of water-soluble substances in coffee powder has its ideal time, if the powder is very fine and cooked for a long time, resulting in over-extraction, the coffee may be very bitter and lose its aroma. On the other hand, if the powder is coarse and cooked too fast, resulting in insufficient extraction, the coffee will be tasteless because it is too late to dissolve the water-soluble substance in the powder.

Use mortar and pestle. Using this method, it is best to grind only a handful of beans at a time, otherwise the beans will jump around. It may miss the point at first-every pestle of beans will jump in the bowl, but just try it a few more times.

Use a hammer. Anyway, it's just to make the coffee beans chopped up. The easiest tool to think of is the sledgehammer!

Put the coffee beans in a thick fresh-keeping bag or parchment bag, then wrap them in a towel. Hit the towel with a meat stick or hammer. Unless your technique is very stable and the force is very uniform, the chopped coffee must be of different sizes. Although this cup of coffee is not the best you have ever made, it must not taste bad.
