Is there a difference between fine and coarse coffee powder?- Coffee powder common grinding thickness map

In addition, the grinding thickness of coffee beans will also affect the taste. Under the premise of consistent objective conditions, the finer the grinding, the more obvious the bitter taste of coffee will be, and the opposite will be concealed.

Coffee other rich taste, the coarser the grind, the more sour, sour too much will make coffee difficult to drink, so want to show a unique flavor of coffee, you can also fine-tune the grind to achieve the effect. However, this adjustment should be a moderate fine adjustment based on the corresponding grinding degree of the appliance.

This is the biggest variable point, because our body is not an instrument, the strength of the powder is based on the feel, for the novice is not there to feel, only the strength is small, even if it is the veteran on the bar, the first two cups every day is also to find the feeling of strength, because we may because of the physical state of the day or even the mood directly affects the exertion of strength.

But also this point, I think the most can increase stability, when you use the same kind of beans, find a good scale, determine the amount of powder, with a force that you think is more comfortable, if you can make a decent esp, then basically done. The reason why the powder pressure can be adjusted to increase stability is that the scale and powder loading amount, as well as the beans themselves, will produce certain small errors due to the environment. And this error, in most cases can rely on the weight of the powder to improve the stability of the extraction effect.

Why does changing beans make a difference? Is the bean bad?

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 the speed of grinding and the size of particles. As a result, the powder thickness scale, powder amount and powder pressing strength of beans before appear to be somewhat weak, just like you can't wear your wife's shoes hard on your feet. Therefore, many foreign restaurants will use fixed bean grinders for fixed beans, in order to ensure the stability of their grinding effect as much as possible.

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