Coffee Technology how to grind Coffee correctly
Before making coffee, we need to grind the beans into fine particles to release the charming aroma and taste of coffee. Therefore, it is particularly important to choose the right degree of coffee grinding and grinding. How should we choose the coffee mill, and how should we set it? To this end, we can judge the degree of grinding of coffee by the following four points.
1. The extraction degree of coffee
The rougher the grinding, the longer the brewing time of the coffee, which can fully extract the essence of the coffee. On the contrary, the finer the degree of grinding, the shorter the brewing time of coffee. Normally, coffee powder with rough grinding takes 4-8 minutes to extract, while coffee powder with finer grinding takes only 1-4 minutes.
two。 Flow velocity
Water passes quickly through rough coffee powder, and vice versa.
3. The feel of coffee powder
The easiest and most effective way to judge the grinding degree of coffee powder is to feel the thickness of coffee powder with your fingers. We only need to take a small pinch of coffee powder and rub it repeatedly between the thumb and index finger to roughly determine whether the coffee powder is thick or fine. To put it more vividly, the rough ground coffee powder feels like sea salt, the medium coffee powder feels like sand, and the delicate ground coffee powder feels more like granulated sugar.
4. The taste of coffee
The ultimate criterion for judging the degree of coffee grinding is the taste of coffee. Taste is a very objective sensory feeling. You only need to judge the following points to easily determine whether the degree of grinding of coffee is correct. If the coffee is too bitter, or too astringent, or too strong, then you need to adjust your coffee mill to fine-grind it; if the coffee is too sour, too light, or if the taste is missing, then you need to thicken it next time. With a little adjustment, the taste of coffee will change a lot. So let's constantly adjust our coffee mill to find the most fragrant and delicious coffee.
