Introduction to the producing countries of coffee bean varieties and grinding-research relationship

Manual brewing, siphon pot, if I say medium grinding fineness, I am afraid you think what I said is not detailed. But it must depend on the player's habits and production genre. After playing at this level, Uncle Dou won't talk any more. The uniformity of grinding is a relative index. There is no absolute uniform grinding machine in the world, but the proportion of coarse and fine particles is more or less different. Let's not dwell on this too much.

Friends who grind beans with an electric grinder suggest shaking while grinding. The action is like shaking up and down by drawing lots in a temple, and avoid shaking horizontally. Grind it for a while and then take a look to see if it meets the fineness requirements. If you don't shake it, it will appear that it has already become a face at the bottom, and it is still the case of beans above! Some friends hope to take some pictures so as to be as intuitive as possible. Please allow Uncle Dou to try, it depends on the camera and the shooting effect.

French filter press, plug air, drip filter or mocha pot do not require high fineness of coffee powder. Knife milk grinder (commonly known as bean chopper or propeller grinder) can not adjust the scale, but to adjust the size of coffee powder according to the length of time, the size of coffee powder is uneven, so it is not suitable for making espresso. It is generally believed that as long as you have an espresso machine, you can make delicious Italian coffee, which is only half right, and the other half depends on a more sophisticated double-gear bean grinder. The lower gear of this bean grinder is connected to a powerful motor, providing a force for high-speed rotation, while the upper gear is connected to the scale and twisted in the reverse clockwise direction, the reading of the scale is getting smaller and smaller, and the upper gear is falling, narrowing the distance between the upper gear and the lower gear. This means that the finer the coffee powder is ground. If the upper gear is twisted in the clockwise direction, the larger the scale value is, the higher the upper gear is and the larger the distance between the upper gear and the lower gear is, so the coffee powder is thicker.

Double-gear bean grinder is to adjust each other's height to set the size of coffee powder, do not underestimate this kind of bean grinder, its structure is incomparably precise, without double-gear bean grinder, it is impossible to make thick, authentic espresso.
