The technology of coffee grinding three stages of coffee bean grinding

The task of grinding roasted coffee beans into powder is called crushing and grinding coffee beans.

It is said that Beethoven put sixty coffee beans into the grinder every morning, grind and then brew the coffee while grinding the coffee while enjoying its aroma. And then experience the fun excitedly. According to its size, the grinding methods of coffee beans can be divided into three types: rough grinding, medium grinding and fine grinding. Use the appropriate grinding method according to the coffee utensils. 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.
