Grind degree of hand-brewed Coffee how to choose the Sugar Grain to adjust the effect of proper Grinding degree on the Flavor of Coffee

Before the coffee is brewed, the coffee beans will be put into the bean grinder for grinding. If the coffee beans are not ground, can they be brewed?

In fact, it is possible. After baking, coffee beans have been extracted with air moisture from the moment they come into contact with the air, so the preservation of coffee beans is also an important factor in determining whether coffee is good or bad. in terms of brewing efficiency, the flat area of a coffee bean is only 1 square centimeter, while after coffee beans are cut into two halves, the unfolded surface area is larger than that of uncut coffee beans. On the other hand, the area of water will increase after passing through the coffee beans, and the substances in the coffee beans will be more easily exposed to water, improving the brewing efficiency.

Generally speaking, due to the difference of each bean grinder, according to the reference of real life, the recommended grinding degree is fine sugar grains, and the coffee brewed under this grinding degree tastes better.
