Coffee brewing method: the importance of hand-made coffee grinding

I believe many people know that coffee is made of coffee powder, not soaked coffee beans, then the process from coffee beans to coffee powder is grinding. After grinding, the coffee becomes powdered. When Xiaobian first touched the hand-brewed coffee, he noticed that the powdered coffee was both big and small, so the size of the powdered coffee had little effect on a cup of coffee.

The editor tells you that the impact is enormous.

In the process of hand-brewing coffee, we have a very important step, that is, steaming, the process of steaming is the full contact between coffee powder and water, which determines whether the flavor of coffee powder can show the best state, and the more the size of the powder is concentrated within the target range, the better the flavor can be. If there are too many coarse grains, you will not be able to boil the good taste hidden inside the coffee, and the coffee brewed will not have enough aroma; if there are too many fine grains, the water will come into contact with the coffee powder too much, it will extract too many unnecessary impurities, and it will make coffee that tastes too miscellaneous and bitter, and the bitter taste will come out.

There are four basic principles of coffee grinding:

The main results are as follows: 1. Select the grinding degree suitable for cooking method. Adjust properly according to the characteristics of the bean grinder and the degree of baking. Generally speaking, the shorter the cooking time, the more the coffee powder must try its best to expand its surface area to come into contact with water, and the finer the particles required; on the contrary, the longer the cooking time, the thicker the grinding particles must be, so as to avoid the extraction of unnecessary impurities.

2. The temperature produced during grinding should be low. No matter what kind of bean grinder is used, it will generate heat by friction during operation, and the speed of volatilization will be accelerated during this heating process, so try to make sure that the temperature produced during grinding is low.

3. The powder particles after grinding should be uniform. The importance of uniform powder has been mentioned before, but the editor will not talk about it here.

4. Grinding must be done at the last minute before cooking. Grinding too early will increase the surface area of coffee in contact with air and humidity and gradually lose its aroma.

After the coffee bean is ground, the cell wall will completely disintegrate, the area of contact with the air will increase a lot, all the lines of defense to protect the fresh will be completely removed, the rate of oxidation and deterioration will be faster, and the coffee will lose its flavor within 30 seconds to 2 minutes. Therefore, do not buy coffee powder, to buy coffee beans, must be ground before drinking, grinding should be quickly brewed.

To grind well, you need to choose an excellent bean grinder. Choosing an excellent bean grinder is like choosing your own lover, and it is also inevitable to experience ups and downs. Here, the editor can only tell you some of the previous experience, and the specific usage habits should be tried and grasped by the brown friends themselves. The bean grinders on the market are roughly divided into two types according to the way they work. Wait, someone might ask why they don't classify us according to flat knives, conical knives and ghost teeth. All right, I'll tell you what! Because each brand of bean grinder produces its own cutter head structure, and its advantages and disadvantages are also different, the editor adheres to objectivity and does not want to bring too absolute views to brown friends, so, brown friends should obediently explore for themselves!

Back to the point, the bean grinder is divided into two types according to the working mode: the hand grinder and the electric grinder.

The hand bean grinder is generally suitable for beginners, or those who like to make their own coffee at home, and most of the hand bean grinders are exquisite in shape, and the editor has seen that many girls start to touch coffee because they like the hand bean grinder. The hand grinder is the first choice of German Zassenhaus.

Electric bean grinder is relatively professional and suitable for commercial or high-end enthusiasts. Prices are also high and low, brown friends still have to choose their own bean grinder according to their economic strength. Editor, let me recommend some brands to you. MAZZER in Venice, Italy, BARATZA in the United States, KALITA in Japan, TIAMO and Zhengzheng in Taiwan, Huijia made in China, and so on. If you use it for domestic use, then you can choose a small flying eagle from Taiwan.

Grinding is the beginning of making a delicious cup of coffee! I hope everyone can make a cup of delicious coffee!
