Introduction to the skills of powder extraction and powder extraction of Italian coffee

The scale is just a reference, different brands have different grinding scales, and the performance of the same model bean grinder of the same brand under the same scale is not exactly the same. it is better to understand it this way: the scale just tells you which direction is thick and which is fine. when you find a suitable powder thickness, the role of the scale will show a little bit. The premise is that only your bean grinder, and can not change the beans, the amount of powder does not change, the strength of the powder can not be changed.

Remember a little trick: when you find the right powder thickness, twist it or pinch it with your hand from time to time, feel it with your body and write it down as much as possible, so that even if you change the bean grinder, you don't have to rely solely on the scale to judge. If you pinch it with your hand, it's obviously thicker, and it can greatly improve the efficiency. I can tell you how much powder I use. But it's about my beans, my grinder, the size of my powder, the strength of my powder, which are closely linked and have a direct impact, and when you change one of them, you have to change the rest. 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 18g for a double.

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 it is also this point, I think it can increase the stability most. When you use the same kind of beans, find the scale, determine the amount of powder, and use a force that you think is more comfortable to press the powder, 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.
