Grinder gear adjustment: how to choose the right grinding time

In general, the adjustment time of the coffee grinder gear should be between 15-20 seconds, but the specific time needs to be determined according to the type of coffee beans and taste.
1.Ways to adjust the grinding gear
The grinder gear generally has a digital scale from coarse to fine, and the smaller the number, the finer the beans. In practice, it is generally recommended to choose the middle gear, and then make appropriate adjustments according to the type of coffee and taste needs.
If the grinding time is too short, the water will be too fast, the coffee taste is too shallow, and there is no rich layer. If the grinding time is too long, it will cause the water to be too slow, the coffee taste bitter, and the moisture content is too low, and it is not easy to maintain the fresh taste of coffee. Therefore, it is necessary to make accurate adjustments according to the thickness of the beans, the coffee model used, the ambient temperature and other factors.
2.Tips for adjusting the grinding time
Generally speaking, the grinding time should be between 15-20 seconds. But the specific time to choose should be according to the type of coffee beans and taste. If you are using a full-bodied coffee bean, you can appropriately extend the grinding time to obtain a stronger flavor. If you use aromatic coffee beans, you can appropriately shorten the grinding time to maintain the aroma of coffee. If you are using a fully automatic coffee machine, you can try to set a few preset modes in advance, and then fine-tune it by the actual performance of the taste. If you use a hand coffee machine, you can adjust it according to the type of coffee beans, the degree of roasting, the water temperature, the amount of water and other factors.
In short, the choice of grinding time needs to consider many factors, including the type of coffee beans, taste needs, grinding machine gear, environmental temperature and other factors. Only through continuous practice and exploration can we master the precise control of the grinding time
