How to adjust the thickness of the Italian coffee grinder?

See a friend said to buy coffee powder directly, I personally recommend people in large and medium-sized cities, it is better to buy fresh coffee beans and grind them themselves. To make a good cup of coffee, the most fundamental thing is to have fresh and high quality coffee beans.

If you buy better by hand mill, you can make sure that the coffee powder is evenly ground. If the grinding is not uniform, it will make the coffee taste not "pure". Because of the different contact area, hot water extracted from coarser coffee powder is much less than from fine powder at the same time. When the extraction time is just enough to fully extract the "good taste" from the coarse powder, it is already over-extracted from the fine powder-there will be some flavors that we do not want to appear. The main purpose of hand-made single product is to taste the original flavor of coffee, and it is to enlarge a certain characteristic of coffee flavor to taste it carefully. Therefore, we should try our best to ensure that the extraction is uniform rather than mixed with various flavors.

water. Now everyone pays attention to the soft water for drinking water, and the soft sailor tastes better. The water temperature is 85-95 degrees Celsius, too high temperature will cause coffee to have a scorched taste, and too low temperature will give coffee an unpleasant sour taste (just right coffee will also have a light sour taste, but this sour taste is pleasant, such as light fruit acidity.)

Pay attention to the warm cup. All utensils used in the process of hand brewing should be kept warm so that the taste of the coffee is warmer and moist.

The thin-nosed pot for hand flushing can be purchased separately, or you can choose some common utensils instead, as long as you ensure that the flushing flow is fine and stable. Of course, try to keep warm as much as possible.

According to my experience, 250 milliliters of coffee for every 15 grams of coffee powder is an appropriate proportion.

Remember that fine is over-refined, rough is plain, and everyone's scale will not be the same.

Different bean grinders have different adjustment dials, so you should check the model of the coffee grinder and read the instructions carefully to determine the direction and strength of the dial. In general, if you keep in the habit of checking the settings of the bean grinder, you only need to make very small adjustments. As long as you move the turntable within 3 mm, you can change the thickness of the powder. Although 3 mm is a very small number, the grinding time of the same coffee beans will change for 3-5 seconds to observe the coffee powder. High-quality coffee powder should be powdery and gravel. If the coffee powder is soft, like flour, it means the powder is fine. On the contrary, if the coffee powder feels tough and rough, it means the powder is too coarse. When the coffee bean enters the grinder, the blade in the grinder will crush the coffee bean into powder. The smaller the distance between the blade and the blade, the smaller the coffee beans will be ground into smaller particles. The finer the ground particles are, the tighter they will be.
