Put the filter paper into the filter bowl, add a small amount of water, so that there is no air bubble between the filter paper and the filter bowl; grind the coffee powder and load it evenly (this process is called cloth powder, some people think that the uplift in the middle of the powder pile can make better coffee, while others think that a hole should be dug in the middle of the powder pile. ⋯⋯this depends on personal understanding.) Slowly pour the hot water of about 92 degrees into the coffee powder, controlling the amount of water just one drop from the bottom of the powder pile; let the coffee powder fully absorb the hot water for about 40 seconds (at this time, if the coffee powder is fresh enough, you will see the coffee powder obviously expand); empty the utensils that hold coffee under the filter bowl (including hot water for warm cups and a drop of hot water just dropped for soaking coffee). The water temperature dropped to about 90 degrees in these 40 seconds, which is just right to start hand flushing; slowly flush the water and draw a circle from the center of the powder pile in one direction, circle after ⋯⋯, drink.

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.
