Skills in the use of thin-mouth pots
The design of the fine spout pot is convenient for the user. The water outlet must be thin, otherwise it is difficult to draw a circle on the coffee powder.
Filter paper drip method and flannel drip method of water injection techniques directly affect the "stuffy steam" effect.
The goal of water injection: 1 stable and controllable water yield 2 undoped air:
1 In order to ensure that the water output is stable and controllable each time, it is necessary to fix the amount of water in the pot and the water injection posture, so that the angle of inclination of the fine-mouthed pot and the amount of water output can be maintained at a certain level.
When injecting water, hot water should be injected vertically from 3 to 4 cm away from the coffee powder surface, and the water column seen at this time should be transparent cylindrical. If the water injection position is too high, the water column will have twists and turns on the way to mix unnecessary air, and the mixed air will be ejected from the surface of the coffee powder being stewed, causing holes to affect the extraction.
In addition, the water temperature in the outlet pipe of the fine-mouthed pot will be higher than the water temperature in the pot. Before the first injection, part of the water should be poured out so as not to affect the extraction.

Selection of water temperature for filter paper dripping method
When using the filter paper dripping method, the water temperature can best achieve the taste balance in 82C~84C.
