Why is it different when you change beans? Is it bad for beans?

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.

[packing pressure] is divided into light pressure and heavy pressure. Its main purpose is to make pressed powder complete after uniform force.

①, light pressing even with the weight of the cake hammer itself.

②, heavy pressure, even if the use of artificial external forces.

Due to too much artificial force, packing is one of the biggest factors in the whole ESPRESSO extraction process, so experienced baristas choose light pressing to ensure product consistency.

This is the biggest variable, because our body is not an instrument, the strength of pressing powder is based on the feel, there is no feel for the novice, only powerful and small, even for the veteran on the bar, the first or second cup every day is to find the feeling of strength, because we may directly affect the exertion of strength because of our physical state and even mood on that day.

But also at this point, I think it can best increase stability. When you use the same kind of beans, find the scale, determine the amount of powder, and press the powder with a force that you think is more comfortable, if you can make a decent cup of esp, you will basically be done. The reason why it is said that the powder pressing strength adjustment can increase stability, because the scale and powder loading, as well as the beans themselves will have a certain small error due to the environment. In most cases, this error can be improved by the weight of pressing powder to achieve a stable extraction effect.
