Coffee bean grinding detailed explanation: the operation of grinding roasted coffee beans into powder is called grinding coffee beans. Props called grinders.

It is said that Beethoven counts sixty coffee beans every morning and grinds them, then brews coffee, grinds the coffee, enjoys its fragrance, and then excitedly experiences the fun.

According to its size, the grinding methods of coffee beans can be divided into three types: rough grinding, medium grinding and fine grinding.

There is also medium fine grinding or very fine grinding (powdered coffee powder) which is finer than fine grinding. The timing of grinding coffee beans is before brewing coffee, only the need for grinding is the top grade. After the coffee bean is ground into powder, its surface area increases and absorbs moisture, which is easy to oxidize. In short, with the passage of time, coffee powder also plays a role of deterioration to damage the flavor. And after the ground coffee beans are placed, the carbon dioxide retained inside the beans will be lost together with the aroma. In this way, when the coffee powder is extracted and filtered, the coffee powder should be expanded without expansion, and you can't make delicious coffee anyway. The secret is to consider grinding and homework consistently, so brewing coffee is the most delicious and mellow. Fine grind ◎ fine grinding (fine particles, the same size as granulated sugar) Medium grind ◎ grinding (particles are the same size as a mixture of granulated sugar and coarse white sugar) Regular grind ◎ coarse grinding (coarse particles, the same size as coarse white sugar)
