Does the thickness of the coffee grind have anything to do with the taste? Common grinding thickness diagram of coffee powder

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.

According to the European Fine Coffee Association (SCAE-Speciality Coffee Association of Europe), the rough grinding of the French filter pot indicates that each bean is crushed into 100,300 particles, each about 0.7mm in diameter. In the medium rough grinding of the electric filter pot, each bean is ground into 500 grains of 800 particles, with a diameter of about 0.5 mm. Moderately ground by hand and siphon, each bean is ground into 1000 to 3000 particles with a diameter of about 0.35. The fine grinding of espresso in which each bean is ground into 3500 particles with a diameter of about 0.05mm. Turkish coffee is ground into a flour-like ultra-fine powder, and each bean is ground into 15000mm 35000 particles.

The thickness of coffee bean grinding is also related to the extraction time. Generally speaking, the longer the extraction time is, the thicker the coffee powder is. The sour coffee extracted by the coffee powder is heavier, and the shorter the extraction time is, the coffee powder is ground finer, and its taste is more bitter than the coffee extracted by the coarse coffee powder. But not all machines follow this rule, and there are some exceptions. Therefore, if the coffee is extracted by the same machine in the same coffee bean, the thickness of the ground coffee bean can be adjusted to change the taste and flavor of the coffee.

The amount of grinding and the thickness of the powder are related to the variety of coffee beans, generally light and moderate roasted coffee beans have a thicker powder. General depth, French, black roasted coffee beans grind out finer powder. The standard of grinding amount is 7g ±0.8g when using conventional bean grinding pot each time. The main requirements for thickness are as follows: G ≥ 0.711mm 50% ≤ 0.711 ≤ g ≤ 0.355 mm,30%;g ≤ 0.355 mm,20%. At present, we, the United States with EIGHTO? CLOCIC beans, Europe uses TCHIBO as the standard bean to design grinding capacity and fineness. In the detection of the thickness of coffee beans, it can be directly used to determine, and in those large coffee bean processing plants, it can also be used to determine and analyze the magnetic metal content in coffee beans.
