How to flush fine coffee powder? The grinding of coffee beans can not be the same, so there is a cup test grinding in the coffee industry, that is, the coffee beans are grinded and poured into the 20mm sieve, and the screening rate reaches 70%. The general evaluation of coffee beans is carried out under this degree of grinding. The reference in daily life is the size of fine granules of sugar.

Qianjie coffee suggests using the grinding degree as the reference point. If the coffee particles are smaller than fine granulated sugar, we can use high water temperature and low time to brew coffee beans in the way of drip filtration. We can use the water temperature of 90 degrees. The brewing time ends in 1 minute and 20 seconds.
