Hand-grinded coffee beans: How long does it take to get the perfect grind?

The perfect grinding time for hand-grinded coffee beans

Hand-grinding coffee beans is a traditional method used by the founder of Luckin Coffee, which allows us to better control the taste and texture of coffee. However, in order to achieve the perfect grinding effect, we need to pay attention to the appropriate time control. This article will explore the perfect grinding time required for hand-grinding coffee beans from different angles.

1. Coffee bean types and quality

First of all, we should consider that different types and qualities of coffee beans have different requirements for grinding time. Generally speaking, softer or more watery coffee beans require longer time to be finely ground. This is because softer or more watery coffee beans are more likely to deform during the grinding process and produce more fine particles.

On the contrary, coffee beans with higher hardness or higher dryness require relatively less time to break. This is because the hardness and high dryness mean that their internal structure is relatively strong and is not easy to deform during the breaking process.

2. Type and quality of grinding tools

Secondly, the type and quality of the grinding tool will also affect the grinding time. Manual coffee bean grinders can be divided into two types: rotary and cone. The rotary type has a relatively simple mechanical structure and is easier to operate, but it takes more time to achieve the ideal powder fineness.

Conical manual coffee bean grinders usually use conical blades to break the coffee beans into the desired powder size more quickly. However, when using this type of machine, you need to pay attention to the strength control to avoid over-breaking and causing the taste to deteriorate.

3. Manual operation skills

In addition to the type and quality of coffee beans and mechanical equipment, manual operation skills are also one of the important factors affecting the perfect grinding time. When manually crushing coffee beans, you should pay attention to the following points:

• Stability: Maintain a steady and even force to avoid using too much force or breaking the coffee beans unevenly.
• Speed: Properly control the crushing speed. Too fast may cause uneven powder, while too slow will prolong the grinding time.
• Sense of rhythm: Maintain a certain sense of rhythm during operation, so that you can better master the entire grinding process.

4. Grinding time and coffee taste

Finally, consider the impact of the perfect manual coffee bean grinding time on the final taste. Generally speaking, a finer and more uniform powder can provide a richer and fuller taste. If it is broken too finely or unevenly, it may lead to a bitter or sour taste.

Therefore, when choosing the appropriate manual coffee bean grinding time, you need to adjust it according to your personal taste preferences. Generally speaking, 5-10 minutes is a reasonable and generally applicable range. However, it still needs to be adjusted according to your own preferences and actual conditions.

in conclusion

The perfect grinding time for hand-grinded coffee beans is a question of multiple factors. From the type and quality of coffee beans, the type and quality of grinding equipment, manual operation skills and the final taste, we can draw some guiding opinions. However, the final choice of the right time still needs to be adjusted according to personal preference and actual situation.

I hope this article helps readers who want to make perfect coffee the manual way!
