I bought a italian coffee machine the other day and made coffee at home. These days, I began to find that there are many fine powders of coffee powder in the brewed coffee. What's the reason
The grinding is too fine. The thickness of the powder is third-class, and italian coffee machine is suitable for medium-thick coffee powder, that is, more than half of the coffee powder can pass through the 0.355mm sieve and cannot pass through the 0.7 1mm sieve. At home, you can only rely on your feelings, just a little smaller than Banlangen granules.
