Coffee extraction failed again? The coffee powder is ground regularly

Coffee extraction failed again? Grinding coffee beans may seem complicated, but there are actually rules to follow.

How to grind coffee powder to the best degree? Let's take a look at the rules of grinding coffee powder!

The degree to which coffee powder should be ground depends mainly on three factors:

A. Coffee bean grinding method and selected utensils

According to the size, it can be divided into three types: coarse grinding, medium grinding and fine grinding. Different coffee utensils are used for different degrees of grinding coffee powder. The specific usage is as follows:

Fine grinding: espresso machine, moka pot, Turkish pot;

Medium grinding: hand pouring kettle, siphon kettle;

Coarse grind: French press, electric drip kettle.

You can also do a sort:

French press (thickest) > electric drip pot > hand pour pot, siphon pot, smart cup > moka pot > espresso machine > Turkish pot (thinnest)

In addition, the following three points should be noted when grinding coffee beans:

a. Frictional heat should be suppressed to the minimum, because heat will cause the loss of fragrance.

b. Whether the size of the coffee beans is uniform. If the coffee beans are not uniform, the concentration of the brewed coffee will be uneven.

c. Grind just before brewing.

B. Roasting degree of coffee beans

Dark roasted coffee beans have a higher solubility rate, so when we encounter dark roasted coffee beans, we need to use a slightly coarser grind. On the contrary, the lighter the coffee beans are roasted, the finer they should be ground.

C. The flavor of coffee

The flavor of coffee is closely related to the coarseness of the coffee powder. Generally speaking, the coarser the coffee powder, the stronger the acidity; the finer the coffee powder, the more bitter it is. For the same type of coffee beans, if you want a mellower cup of coffee, you might as well grind the powder finer; if you want to drink a fruity flavor, you can grind it coarser.

If your coffee extraction fails again or the brewed coffee is not as good as the one in the cafe, it is better to check whether the coffee powder is ground correctly.
