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.

About the fineness of ground coffee beans. As there are so many ways to make coffee, there are many ways to make coffee. Now I would like to introduce to you the reaction of grinding thickness to taste. The thickness of coarse ground caffeine is lower and its acidity is obvious. On the contrary, the alcohol has high thickness and low acidity. Of course, it also has something to do with the time of extraction. The cooking time is long and the thickness of alcohol is high, but the thickness of short alcohol is low. You can arrange and combine according to these two sets of relationships. The high mellow degree mentioned here does not include the situation in which the coffee is scorched.

The ideal time to grind coffee is to grind it before steaming.

Because ground coffee is easy to oxidize and lose its flavor, especially without proper storage, coffee powder is also easy to change flavor, so it is naturally impossible to brew mellow coffee.

Some people are afraid of trouble or do not want to buy a bean grinder. They usually buy ready-made coffee powder when they drink coffee at home. At this time, they should pay special attention to the problem of storage. After opening the coffee powder, it is best not to place it at room temperature at will. The more appropriate way is to put it in a sealed jar. Because the coffee powder is easy to absorb, an accidentally becomes a strange taste of coffee, then no matter how good the quality of coffee is ruined.

However, some people put the steamed coffee powder in the refrigerator as deodorant after sun-drying or microwave drying, which is a good way to make the best use of things.

When grinding beans, the size of the powder depends on the way it is cooked.

Generally speaking, the shorter the cooking time, the finer the grinding powder; the longer the cooking time, the thicker the grinding powder.

In terms of actual cooking, the ESPRESSO machine takes a very short time to make coffee, so the grinding is the finest, and the coffee powder is as fine as flour; it takes about 3 minutes to cook coffee by siphon, and the coffee powder is ground to a medium-thick thickness; American coffee pots and hand-brewed bubbles are generally coarse and fine.

The proper grinding degree of coffee powder is very important for making a good cup of coffee, because the extraction of water-soluble substances in coffee powder has its ideal time, if the powder is very fine and steamed for a long time, resulting in excessive extraction, the coffee may be very bitter and lose its aroma. On the other hand, if the powder is coarse and cooked too fast, resulting in insufficient extraction, the coffee will be tasteless because it is too late to dissolve the water-soluble substance in the powder.

There are different brands and types of bean grinders for grinding coffee, and the ideal one is a grinder that can adjust the thickness of the beans. Do not use machete grinder, machete grinder easy to cause uneven thickness. In this way, the coarse powder is not enough to extract the fine powder has been over-extracted. It is conceivable that the coffee brewed in this way must be bitter and astringent, with mixed flavors.

When grinding with a bean grinder, do not grind too much at one time, just enough powder for one time, because the longer the bean grinder is used at one time, the easier it is to heat up, which indirectly causes the coffee beans to be heated in the grinding process and causes the aroma to be released in advance, which will affect the aroma of the steamed coffee. Fresh coffee beans are emerald green and must be roasted and cooked, then ground into powder and brewed before they can become the coffee sold by the store.
