How to choose and buy a household small bean grinder?

In addition to considering the appearance style and workmanship, the purchase of a small household bean grinder should also focus on the quality of the inner steel of the bean grinder, the speed of the second grinding bean, the uniformity of the third thickness, and whether the thickness of the ground coffee powder can be adjusted.

It is recommended not to buy a propeller-type bean grinder (that is, the kind of bean grinder driven by a motor with two blades), which is actually not a bean grinder, but a "bean-cutting machine". The shortcomings are that the coffee powder cut out is not uniform; the second is that the process of cutting beans produces high heat, destroying the precious oil and aroma in the coffee beans; and the third is that it cannot adjust the thickness of the coffee powder.

Brewing method VS particle size

First, coarse grinding: size such as coarse white sugar, suitable for filter press coffee.

Second, in the grinding: gravel, the size between coarse white sugar and granulated sugar, suitable for drip filtration brewing method.

Third, fine grinding: size such as fine sugar, suitable for espresso coffee pot, electric coffee pot, mocha pot.

Fourth, very fine grinding: the size is between salt and flour, suitable for Espresso, because the home grinder can not grind this texture, generally must buy ready-made grinding powder, so if you want to enjoy Espresso at home, it is best to drink large quantities, in order to drink fresh coffee.
