1. Powder thickness

How much should the bean grinder scale be adjusted to?

What I want to say is that the scale is only a reference, different brands have different grinding scales, and the same brand models of bean grinders are not displayed exactly the same under similar scales: the scale only states which direction you are going to be thick and which is fine. When you find the right thickness of your powder, the influence skill of the scale is a little bit. The condition is that you only have this bean grinder, and you can't change the beans, the amount of powder fluctuates, and the strength of the powder can not be changed.

Remember a little trick: when you find the right powder thickness, constantly twist it with your hand, pinch it, feel it with your body and remember it in general. Even if you change the bean grinder, you don't have to rely on the scale decisively. If you pinch it with your hand, you will be fine-tuned and obeyed.

two。 Powder loading capacity

How many grams of powder are used to make a single double?

I would like to tell you how many grams of powder you and I use, but that is for my beans, my bean grinder, my powder thickness, my powder strength, these links are closely linked and can have a direct impact, when you change one of them, the rest have to be changed. In principle, we pack more coarse powder and less fine powder, although you should fix the amount of powder you think you aspire to, because the powder quantity and scale are relatively large and should be controlled (compare the numerical value, the scale is how much, the amount of powder is a few grams) for example, I use 9g for a single serving and 16g for a double.

3. Powder pressing strength

This is the largest variable point, 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 novice on the bar, the first or second cup every day is to find the feeling of strength, because we generally have a direct impact on the promotion of strength because of our body shape on that day.

But it is also this point, I think it can increase the shaking, when you use counterbalance to grow beans, find a good scale, determine the amount of powder, with a force that you think is more comfortable to press powder, if you can make a decent cup of esp, then the foundation is done. The reason why it is said that the strength of the powder to adjust can increase wavering, because the scale and the amount of powder, as well as beans because of the situation to produce a small amount of poison. And this outflow poison, in most cases, it is necessary to rely on the weight of pressing powder to improve to achieve wavering extraction results.

4. The influence of beans

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

The formation and density of bean groups of different varieties in different production areas are different, and different baking degrees will also cause a distinction in hardness, resulting in angry changes in the grinding rate and particle size. In the past, the bean powder thickness scale, powder quantity, powder pressing strength appears to be a little powerful, which seems that you can't put your wife's shoes on your feet. Therefore, many restaurants at home will use a fixed grinder for fixed beans in order to ensure that the grinding results will be shaken as far as possible.

So my last 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 wavering strength to find the feel, obedience should be the highest.
