Like drinking coffee, is a hobby, like making coffee, is a kind of mood, like making coffee, is a way of life.

In China, more and more people begin to fall in love with coffee and coffee life. Baristas constantly study how to make better coffee. They constantly try the different flavors of coffee beans in different places, the different tastes brought by various brewing utensils, and the personality shown by various brewing techniques, but often ignore the importance of bean grinders to all this.

Among the factors that determine the taste of coffee brewing, "beans", "grinding" and "machine" are hardware factors, and "technology" is software factors. today, Chongqing Brista Coffee West Point training School will discuss in detail the impact of "grinding" on coffee taste.

At present, there are many kinds of bean grinders on the market, but they can be divided into parallel grinding, conical grinding, roller grinding, ghost tooth grinding, machete grinding and so on. Among them, the roller mill is mostly used in large factories to crush beans like a noodle machine, which has high grinding efficiency, but is not suitable for cafes, while machete grinding is mostly a household simple bean grinder, which uses a blade to tell the power of rotation to chop up beans with extremely low uniformity and high calorific value, which is not conducive to the extraction of coffee flavor. Parallel mill and conical mill are the mainstream grinding discs at present, and the differences are as follows:

Generally speaking, the parallel grinding disc has the advantages of fast rotational speed, fast grinding and more uniform grinding, while the disadvantage is easy to heat and relatively short life, while the tapered grinding disc has the advantages of not easy to heat and long life, and the disadvantage is slow and uneven.

At present, the Japanese Fuji ghost tooth grinding plate can grind more uniform coffee powder, at the same time produce less fine powder, and the grinding efficiency is higher. But it is not suitable for the extraction of espresso.
