The knack of grinding beans how to grind beans the importance of grinding coffee beans

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.

We'll tell you how to grind the coffee beans.

Fine grind ◎ fine grinding (fine particles, the same size as sugar)

Grinding in Medium grind ◎ (particles the same size as granulated sugar mixed with coarse white sugar)

Regular grind ◎ rough grinding (coarse particles, the same size as coarse sugar)

The knack of grinding coffee beans

The grinding prop for coffee beans is a grinder. There are numerous types of mills ranging from manual at home to electric for business. Household grinders can also be used as decorations, and the number of people need more than one grinding, or electric to facilitate. According to the structure of the grinder, there are grinders that use vertical and horizontal groove blades to cut coffee beans and those that grind coffee with molars. Each has its own advantages, and the situation of business use tends to mass production of the electric type as the mainstream.

However, the most important thing to pay attention to when grinding coffee beans is the following two points: ① friction heat suppression to a minimum. (the aroma will be dispersed due to fever) whether the size of ② particles is uniform or not. (if the particles are uneven, the concentration will be uneven.) taking this as a consideration, if you are a household mill, you should rotate gently and be careful not to produce friction heat as much as possible. Therefore, it is more appropriate to use electric grinders. The usage of the grinder is to grind the beans before brewing. There are two kinds of domestic mills: manual and electric. The manual type is used if the number is small, while the electric type is more convenient for the large number of people. With the bubbling apparatus to determine the grinding method (particle size) the manual grinder should be careful not to produce friction heat only. And pay attention to whether it is mixed with other things. Whether the granules of ground coffee beans are large and neat or not should be checked. (in the case of uneven particles, it is possible that the function of the grinder is always, or coffee roasting is uneven, etc.) meet good water, coffee is the essence extracted after the meeting of coffee powder and water. Therefore, in addition to good coffee beans, water quality and water temperature are of course the key role in releasing the aroma of coffee.

Control the proportion of every 180 ml of water with 10 grams of ground coffee. No matter how much coffee is brewed, it is best to prepare it in the same proportion. Of course, you can also according to your own best conditioning ratio, but if you use less coffee powder, or if you grind too fine, the brewed coffee will be light and bitter. Do not reheat the brewed coffee at the drinking temperature. Make coffee before each drink, and only soak the amount you want to drink. The temperature to maintain the best flavor is about 86 degrees Celsius.
