Will the roasting degree of coffee beans affect the grinding? what is the grinding degree of different roasted coffee?

When we brew coffee, we may all encounter the same problem, that is, when we brew different coffee, we all choose different utensils, so for coffee beans, the degree of grinding is different for different roasting degrees. The shallow roasting, moderate roasting and deep roasting of coffee beans are all different.

Today, Qianjie Coffee takes the grinding of medium-roasted coffee beans as an example. The grinding degrees of various brewing tools are as follows:

1. The grinding state of espresso is probably close to that of powdered sugar, because the grinding degree is more fine, in order to avoid longer grinding time to produce more heat, a larger knife head is usually needed, and the general bean grinder is not competent. It is recommended to use a special grinding machine for espresso.

two。 The grinding state of the siphon pot is mostly fine grinding, which is about the size of fine granulated sugar, and the surface area is larger to speed up the extraction, but due to the long cooking time, it is not suitable to use the grinding degree as fine as semantic concentration.

3. In recent years, most of the popular hand flushing and American trickling filter bottles are medium grinding, and the particles are usually slightly larger than fine granulated sugar, because they are soaked for a long time. If you use fine grinding, too much odor will be extracted.

4. The grinding degree of the French filter kettle generally belongs to rough grinding, and the grinding size is about the state of crystal rock sugar.

The above is the usual situation, as there is no absolute in the world of coffee, do not be surprised if you have a chance to see the barista's hand flushing, the grinding degree is close to the fine grinding of the siphon pot, the other party may adjust the brewing method, water injection size and water temperature accordingly. When practicing at home, no matter what kind of cooking equipment you use, keep in mind that each extraction adjustment, change only one object at a time, in order to reduce factors.
