Coffee mill thickness difference shelf life flavor description taste treatment variety

If you use a coffee cup with a scale, that's great. But you still need to measure the total weight of the coffee to better determine whether the grinder needs to be readjusted. If you use an automatic divider, the total weight of the coffee you make will have an error of about 3G. Since the scale on the cup can help you determine the liquid volume of coffee, you need to spend more energy on measuring the extraction time of coffee.

Let me tell you the importance of these data. Whenever we adjust the coarseness of the bean grinder to + /-1 scale, the extraction time of coffee will change by 4-5 seconds, and the total weight of coffee will have an error of 10g.

Since we use a large bean grinder, the above changes may not be so obvious on a small bean grinder. But this is enough to prove how important the data is in debugging the bean grinder.

When you use the same kind of beans, find the scale, determine the amount of powder, use a force that you think is more comfortable to press the powder, if you can make a decent cup of esp, then you are almost 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. 4. Why does the influence of beans become different when changing 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. My bean grinder, my powder thickness, and my powder pressing strength are closely linked and can have a direct impact. When you change one of them, the others have to be changed. In principle, we install more coarse powder and less fine powder, of course, you can fix what you think is the ideal amount of powder, because the powder quantity and scale are relatively controllable (compare the numerical value, the scale is how much, the amount of powder is a few grams), for example, I am used to using 9g for a single serving and 16g for a double. 3.
