First talk about two basic concepts, insufficient extraction, that is, the flow of water through the coffee powder is too fast, or the temperature is too low to fully extract the flavor of coffee. Excessive extraction, on the contrary, coffee water is trapped in coffee powder.

Incomplete summary of extraction
The first coffee will not melt completely when thrown into the water. The maximum extraction rate of roasted coffee beans is 30% (substances that can be dissolved in water divided by the total weight of coffee). This seems to be nonsense: 1. Whether it's French pressure, Philharmonic pressure, all kinds of pressure, or espresso. The range of the best extraction rate is 18% Mui 21%. Insufficient extraction (less than 18%) indicates that the flavor of coffee is not fully soluble.
