How finely ground are coffee beans?

The benefits of finely ground coffee beans

Coffee is a must-have drink for many people every morning, and a cup of delicious coffee is inseparable from finely ground coffee beans. So why do we need to grind coffee beans so finely? Let's explore it from several aspects.

Improve extraction efficiency

First, grinding coffee beans finer can improve extraction efficiency. When water passes through coarse particles, there are many gaps that cannot be fully utilized. When the particles are smaller and more uniform, water can better contact them and penetrate deeper. In this way, more solute substances can be extracted in the same amount of time, making the coffee taste richer and more fragrant.

Increase flavor complexity

Secondly, finely grinding coffee beans can also increase the complexity of flavor. Due to the different components of different parts and types, the size of the particles will affect the contact time and surface area between water and coffee beans during the grinding process. When coffee beans are finely ground, more flavor substances can be released, making the coffee taste richer and more layered.

Improved stability

In addition, grinding coffee beans finely can also improve stability. During the brewing process, larger particles tend to sink to the bottom or float on the water due to gravity. Smaller and more uniform particles can be better suspended in water and remain relatively stable. In this way, the aroma and flavor released by all the particles can be fully utilized during the brewing time.

Extend shelf life

Finally, grinding coffee beans finer can also help extend their shelf life. Larger particles are easily affected by air, humidity and other factors and quickly oxidize and deteriorate, and lose their freshness quickly after opening. Smaller particles that have been carefully processed can better maintain the freshness of coffee beans and extend their shelf life.

in conclusion

In summary, grinding coffee beans finely can improve extraction efficiency, increase flavor complexity, improve stability and extend shelf life. Therefore, when making a cup of delicious coffee, we should choose the right grinding degree and pay attention to keeping the coffee beans fresh. Only in this way can we truly experience the rich and mellow taste of coffee.
