There are many factors to make a good cup of coffee, however, the grinding thickness of coffee beans is most often ignored!

If people who do not usually have any research on coffee, when they receive a bag of complimentary beans, many people will directly take the beans to the store to grind them, but they do not know what kind of brewing equipment they use. This seems to be just the act of grinding beans into powder, but actually covers most of the impact on the taste of coffee.

Generally speaking, the way coffee is brewed is to determine the particle size of the coffee powder. When you use a machine that takes less time to brew, the coffee powder must expand more surface area to come into contact with water, and the finer the particles are needed; on the contrary, when the brewing time is longer, the grinding particles must be bigger and rougher. To put it simply, the longer the extraction time, the thicker the coffee beans will be ground, so as not to cause excessive extraction and let the bitter taste of the coffee run out; the shorter the extraction time, the finer the coffee beans will be ground, so as to avoid insufficient extraction.

According to several coffee machines (brewing methods) that are more common in the market and at home, the thickness can be classified as follows:

1. Hand brewing / American coffee maker (filter paper): intermediate degree

two。 Siphon / French filter kettle: middle roughness

3. Mocha pot: fineness

4. Italian Steam Coffee Machine: extremely fine

To sum up, each kind of brewing utensils has its own advantages, and everyone likes different brewing methods, but in any case, it must be aimed at the brewing method of coffee to match the most suitable grinding degree. only in this way can good beans show its most suitable flavor and give full play to the powerful benefit of one plus one greater than two! If the coffee extraction is insufficient or excessive due to the difference in thickness and fineness, it will affect the taste of the coffee.

So when you want to make a good cup of coffee, don't forget to consider the importance of the grinding degree of coffee beans in the first place.
