The necessity of grinding coffee beans

Coffee is one of the most popular drinks in the world, and grinding coffee beans is a key step in making a delicious cup of coffee. Why do we need to grind coffee beans? This article will explore this issue from three aspects: improving taste, releasing aroma, and controlling soaking time.

Improve taste

First, the taste can be improved by grinding the coffee beans finely. The different coarseness and fineness of the coffee powder will affect the friction and flow rate of water when it comes into contact with it. If the powder is too coarse or too fine, it will lead to uneven extraction, causing some particles to be over-soaked or under-soaked. This will make the brewed coffee taste bitter or turbid.

On the contrary, properly selecting the right particle size ensures that water has full contact with each particle and releases the essence of coffee in the right time. This will make the brewed coffee more mellow and more balanced.

Release aroma

Secondly, grinding coffee beans can release more aroma. When the coffee beans are broken, the volatile compounds inside come into contact with the air, giving off a rich and strong aroma. These volatile compounds are an important component of the complexity and layering of coffee flavor.

If you use pre-ground coffee that has been damaged or has been out of date for a long time, most of the aroma may have been lost. In contrast, freshly ground coffee beans can retain more volatile compounds and release them during the brewing process. The coffee produced in this way not only tastes better, but also brings people pleasure and enjoyment.

Control soaking time

The last reason is to adjust the taste and flavor profile by controlling the steeping time. For the same type of coffee beans, different grinds will result in different steeping times. Coarsely ground coffee will take longer to release its flavor, while finely ground coffee will take less time.

This ability to control the steeping time makes brewing coffee an art. By adjusting the particle size of the coffee beans, the time and intensity of contact between the water and the coffee during the brewing process can be adjusted according to personal taste preferences. This allows you to create the perfect combination based on your preferred acidity, bitterness, and sweetness.

Summarize

In summary, grinding coffee beans properly is an essential step in making a delicious cup of coffee. It can improve the taste, release the aroma and control the soaking time. Therefore, when enjoying a cup of high-quality coffee with rich aroma, rich taste and distinct layers, please remember to choose fresh and properly grind it on the spot.
