It is said that Beethoven put sixty coffee beans into the grinder every morning and then brewed the coffee while enjoying its aroma and experiencing the fun.

Indeed, it is a pleasure to grind the coffee yourself, and the coffee finally ground and brewed seems to be much more mellow and delicious than the ready-made coffee bought outside.

Regular coffee drinkers must have noticed that coffee grinders are standard, whether they go to chain cafes or private cafes. For professional baristas, a good bean grinder is an important step in ensuring the quality of a cup of coffee.

Why is the grinding of coffee beans so important? Ground coffee beans, the surface area will be increased by about 1000 times, it is more convenient to extract active ingredients from coffee beans, so that we can make a cup of rich and mellow coffee in only a few minutes.

With regard to the grinding time, the most appropriate term is "seconds are gone", and the fragrance is gone within 30 seconds to 3 minutes. Therefore, the ideal time to grind coffee is before cooking. Moreover, without proper storage, coffee powder is also easy to change flavor, be sure to drink up within 2 weeks. Otherwise, if one is not careful, it will become a strange taste of coffee, and then even the best quality coffee will be ruined.

The proper grinding degree of coffee powder is very important for making a good cup of coffee, and the thickness of the powder also 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. The thickness of coffee powder varies with different brewing tools.

Hand pot grindability: medium grinding powder hand brewing coffee, generally suitable for medium grinding coffee powder, medium grinding powder is like the thickness of white granulated sugar. When you pinch your finger, you can see a polygonal grain of coffee powder, which is moderate grinding, not flour.

Degree of grinding of siphon pot: the extraction time of siphon pot of moderate grinding powder is generally about 1 minute and the temperature is about 92 degrees. If the coffee powder is too fine, it will not only extract too much, but also clog the catheter when the coffee liquid is refluxing. If the coffee powder is too coarse, it will cause the aromatic substances to be hidden inside the particles and unable to touch and extract with hot water. So medium grinding powder, similar to hand-brewed coffee, is the most suitable.

The grinding degree of the pressure kettle: the rough and medium grinding powder pressing kettle uses the most direct coffee extraction principle-soaking + filtration. So that the coffee extract oil and aromatic substances can smoothly pass through the filter, so the coarse to moderate grinding powder is the most suitable, coarse to moderate grinding powder is as big as millet.

Italian machine grinding degree: fineness grinding powder in the process of extracting coffee with Italian machine, coffee powder must be subjected to high pressure and high temperature, so the powder must be fine and pressed powder should be uniformly pressed so that coffee powder can block water pressure and extract evenly. Fine grinding powder is like fine sand.

Grinding degree of mocha pot: fine grinding powder the extraction principle of mocha pot is the same as that of Italian coffee machine, so the coffee powder must be fine, so the concentrated coffee liquid can be extracted, so the fineness grinding powder is the best.

Belgian kettle grind degree: the principle of Belgian kettle is a bit similar to that of siphon pot. Belgian pot is easier to operate, just pay attention to water and coffee powder, and it is best to use moderate grinding powder when Belgian pot is extracted. coffee grounds and coffee liquid are easier to separate, do not clog the catheter, and the aroma of coffee is just right.

Grinding coffee beans: grind coffee beans at home, preferably after the water is boiled, and then start grinding coffee beans, so that you can retain the original aroma of coffee. Grinding coffee bean tools should also pay attention to the need for a grinder that can adjust the fineness of coffee beans so that you can easily grind coffee powder of various fineness at home. Those who like to enjoy slow life can choose to grind beans by hand and enjoy the fun of grinding beans slowly.

In order to correctly extract the substances from coffee beans, in addition to grinding coffee beans into different degrees of thickness, it is also very important to make the particles uniform in size. If the grinding thickness is different, because the fine coffee powder is extracted by water faster than the coarse coffee powder, it will give rise to the problem that the extraction time is out of control, that is, in the same time, the fine coffee powder is soaked in water for too long. When it has been extracted too much, the crude coffee powder is not enough soaking time, which leads to insufficient extraction. This kind of coffee is definitely not a good cup of coffee.
