Is the bean grinder better by hand or by electric?

There are different differences between manual bean grinder and electric bean grinder. In terms of grinding uniformity and the evaluation of fine powder produced by grinding, the opportunity of electric grinding is better, while the advantage of hand grinder is to show the aroma of coffee beans, but relatively speaking, it produces more fine powder than electric grinder.

A good coffee grinder should meet two conditions: 1, grinding fine powder should be less; 2, particle uniformity should be high. In the process of extraction, the extraction efficiency of fine powder is faster than that of normal particles, which is easy to cause over-extraction and affect the flavor of coffee, while grinding uneven coffee particles is also desirable, some particles are over-extracted and some particles are insufficient, affecting the overall flavor.

Therefore, a good bean grinder attaches importance to the uniform extraction of ground coffee particles in the process of extraction.
