The basic principles of coffee bean grinding: the perfect balance of taste and mouthfeel

Basic principles of coffee bean grinding

Grinding coffee beans is one of the most important aspects that determine the quality of coffee. Through proper grinding, coffee beans can release the best taste and aroma, thus achieving a perfect balance between taste and mouthfeel. Here are some basic principles for grinding coffee beans.

1. Moderate thickness

The coarseness refers to the size of the coffee beans after they are broken. The required coarseness varies for different types and methods of coffee. Generally speaking, when the brewing time is long and the water contact time is long (such as French press) or when solid particles need to be filtered out (such as hand drip), coarser particles need to be selected; while when the brewing time is short and the water contact time is short (such as espresso machine), relatively finer particles need to be selected.

2. High uniformity

Uniformity refers to the degree to which each particle is similar in size. If the coffee beans are not ground evenly, the particle size will vary greatly, which will result in some particles being over-extracted during the brewing process, while others will not fully release their aroma and taste. Therefore, when grinding coffee beans, it is necessary to ensure that the particle size is as uniform as possible.

3. Grinding time control

The grinding time of coffee beans is also one of the important factors affecting the quality. If the coffee beans are too finely ground or the grinding time is too long, the coffee will taste bitter; if the grinding time is too short or the particles are too large, the aroma and taste cannot be fully released. Therefore, when manually or automatically processing coffee beans, it is necessary to control the appropriate time.

4. Immediate use

Coffee beans lose their freshness and flavor easily after being crushed. Therefore, they should be used as soon as possible after being crushed to maintain the best quality.

5. Storage method

For the remaining coffee beans, you should choose the appropriate storage method to maintain their freshness. Generally speaking, storing coffee beans in a dry, cool and sealed container can extend their shelf life.

Summarize

Through the above basic principles, we can better master the skills of coffee bean grinding. Moderate coarseness, high uniformity, proper control of grinding time and immediate use are the key elements to ensure the perfect balance of quality. At the same time, when storing the remaining coffee beans, you also need to pay attention to the appropriate method to prolong their freshness.
