Roasting, which also has a lot to do with the degree of coffee expansion, shallow roasted beans expand relatively small, and it is not easy to extract flavor, so you can increase the water temperature to balance; deep-roasted beans are more water-absorbing and easy to expand, so you can use water of about 87 degrees to extract.
The water temperature, grinding thickness, brewing time and powder amount of coffee can be said to be variables in a certain range. Each quantity has a certain controllable space, but after each quantity changes, the other quantities have to change accordingly, so if you really want to master the brewing skills, you can only rely on experience, and it is impossible to become a barista according to this formula.

After the coffee beans are roasted, the interior becomes a honeycomb-like structure, and the soluble substances adhere to the cell wall. Only by breaking them open and exposing them to water can these soluble substances dissolve in the water. We just got the taste of coffee.
The thickness of the coffee beans determines how quickly the substance in the coffee can dissolve into the water. Because, for the same beans, the contact area between coffee powder and water under fine grinding is larger than that under rough grinding.
