How does a novice choose a bean grinder

Bean grinder plays a very important role in family coffee life, unless you buy coffee powder, you can't avoid grinding beans.

Electric bean grinder and manual bean mill

Coffee grinding should be in line with the principle that the sedan car is now eye-catching. Basically, after all the preparatory work before making coffee has been done, the last process is to grind coffee. Do not grind a large number of coffee beans into powder at home and save them. It would be better for Uncle Dou to grind them for you with a large bean grinder in the store.

We say that coffee should be finally ground before brewing, the reason is that the biggest enemy of coffee is oxygen, and the biggest weakness of coffee is that its aroma is volatile.

Then it is necessary to increase the speed of grinding and shorten the time it takes to expose it to air. Seriously, it is recommended to use an electric bean grinder to grind coffee at home. Convenience and durability, at least to ensure that the coffee powder is not oxidized, the aroma is not easy to volatile requirements. At the same time, the grinding is as uniform as possible.

With regard to the manual bean grinder, its biggest advantage is that it is very interesting and fun. If you can rotate the handle of the manual bean grinder at a faster speed, you can also improve the grinding speed. However, the uneven grinding of the manual bean grinder is real and difficult to solve. This is determined by its principle and structure.

Select the roughness and fineness of grinding according to the apparatus

Introduce to you the method of selecting the grinding thickness of several kinds of instruments. It is recommended to grind the kettle coarsely, because it takes a long time to soak; the mocha kettle and semi-automatic kettle are thinner, but not powdery, but have fine particles; electric drip filtration can be determined according to the taste, if it is thicker, it is finer, if it is lighter, it is thicker.

Assuming that all the conditions do not change, please mention it, only change one link. Such as: the same kind of coffee beans, the same water temperature, the same amount of water are unchanged, the thickness of finely ground coffee alcohol is higher, on the contrary, the acidity is bright.

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.
