Coffee bean grinding method

According to the size of coffee beans, the grinding methods can be divided into rough grinding, medium grinding and fine grinding. Use the appropriate grinding method according to the coffee utensils.

There is also medium fine grinding or finer and finer grinding than fine grinding (powdered coffee powder). The time to grind coffee beans is to grind only the required portion before brewing coffee. 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 coffee 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 the coffee can not be brewed anyway. The secret is to consider grinding and homework consistently, so brewing coffee is the most delicious and mellow.
