How to choose a bean grinder

Electric bean grinder and manual bean mill

Coffee grinding is basically after the preparation work before brewing coffee has been done, the last process is to grind coffee. Do not grind a large number of coffee beans into powder and save them at home. 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. 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.

The difference between manual and electric small bean grinder

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

We say that the most important indicator of coffee grinding is the speed and uniformity of the grinding. The so-called evenness is a relative index, and there is no so-called absolutely uniform grinder at present, so the evenness we are talking about refers to the thickness of the vast majority of ground coffee. Of course, the uniformity of professional coffee mill is better. But if you do not intend to spend so much money, but only want to use a hand mill or a small grinder to grind coffee, the grinding fineness you are adjusting is only a reference value, that is, most powders should be at this fineness. Therefore, friends who use manual bean grinders should observe the thickness of coffee powder after grinding coffee. Judging by the fineness of most coffee powder, it sounds a bit troublesome, but it's the only thing we can do for a grinder such as a hand mill.

It is a fact that a small electric bean grinder (such as a small grinder) grinds coffee with poor uniformity. Therefore, it is suggested that when grinding beans, it seems to shake up and down while grinding beans, such as drawing lots in a temple. The aim is to make the coffee beans as uniform as possible, but only as much as possible. But the biggest advantage of this machine is its fast grinding speed, which retains as much aroma as possible. However, the grinding speed of the hand mill is slow, and the aroma will volatilize a lot. If you must ask me to compare the advantages and disadvantages of these two kinds of bean grinders, I can only say that radish and cabbage have their own preferences. I would rather choose a small grinder, at least it can retain the aroma to the maximum extent.

What we have said so much is to pave the way for future operations. We say that the degree of grinding will be closely related to the extraction time and directly affect the taste. For example, if you grind coffee with a hand mill or a small grinder, the proportion of coffee is more thick, so if you want to get a mellow taste, you need to increase the soaking time. On the contrary, if the fine proportion accounts for more, and you want to pursue bright sour fruit and low-bitter coffee, then you must shorten the soaking time.

Having said so much, we must be on the premise of a previous condition before this conclusion can be established, that is, it is assumed that all the conditions do not change, but only 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.
