Coffee powder thickness adjusted to a few degrees common grinding thickness diagram

The thickness of the powder depends on the color of crema and the proportion of the last cup of espresso. If what the owner said is the relationship between the thickness of the powder and the flow rate in the espresso extraction, under the same packing pressure, the finer the powder, the slower the flow rate; the thicker the powder, the faster the flow rate. When the thickness of the bonding powder is constant, the greater the filling strength is, the slower the flow rate is; the smaller the strength is, the faster the flow rate is.

When the color of the crema meets the requirements, adjust the strength of the powder to reach a flow rate of 2 ounces in 20-25 seconds. (in the amount of double powder) because there are two variables (the thickness of the powder and the strength of the filling), my adjustment is based on: if the thickness is adjusted to the right size, the crema should be reddish brown. If it is too thick, the color of crema will become lighter, and if it is too fine, it will become darker or even turn black.

Of course, for experts, it is based on the implication in the cup, not on the flow rate / flow rate. I'm a novice, so I have to be dogmatic.

The overall composition and density of different varieties of beans in different producing areas are different, and different baking degrees will also cause differences in hardness, resulting in changes in grinding speed and particle size, so that before the bean powder thickness scale, powder quantity, powder pressing strength appears to be a little weak, just like you can't put your wife's shoes on your feet. Therefore, many foreign restaurants will use a fixed bean grinder for fixed beans in order to ensure the stability of their grinding effect as far as possible.

So my final suggestion is, in the case of fixed beans, first set the amount of powder, and then find the powder thickness, and then use a more stable strength to find the feel, the efficiency should be the highest.
