Hand brewed coffee ground bean fineness-coffee powder brewing method diagram

The thickness of hand-brewed coffee and the diagram of brewing method of coffee powder

When grinding beans, the size of the powder depends on the way it is cooked. The shorter the cooking time, the finer the ground powder; the longer the cooking time, the thicker the ground powder. Sixth, in terms of the actual way of cooking, it takes a very short time for the ESPRESSO machine to make coffee, so the grinding is the finest, and the coffee powder is as fine as flour; it takes more than a minute to cook coffee in the "plug wind" way, and the coffee powder belongs to medium-sized grinding; American filter coffee takes a long time to make, so the coffee powder is the thickest, one by one like Beijing grains on a shell beach. Grinding coffee powder with appropriate thickness is very important for making a good cup of coffee, because the extraction of water-soluble substances in coffee powder has its ideal time, if the powder is very fine and cooked for a long time, resulting in over-extraction, the coffee may be very bitter and lose its aroma. On the other hand, if the powder is coarse and cooked too fast, resulting in insufficient extraction, the coffee will be tasteless because there is no time to dissolve the water-soluble substance in the powder.

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 shaky strength to find the feel, obedience should be the highest but also this point, I think it can most increase the shaking, when you use counterbalance beans, find a good scale, determine the amount of powder, press the powder with a force that you think is more comfortable, 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 poison, in most cases, it is necessary to rely on the weight of pressing powder to improve the shaky extraction results, which is the largest variable, because our bodies are not instruments, and the strength of pressing powder depends on the feel of the hand. There is no feel for beginners.

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 bean grinder for fixed beans in order to ensure the shaking of their grinding results as far as possible.
