Why do coffee beans need to be ground?

Coffee is one of the most popular drinks in the world, and making a delicious cup of coffee is inseparable from freshly ground coffee beans. So why do we need to grind coffee beans into powder? This article will explore this issue from three aspects: improving taste, releasing aroma, and increasing nutritional value.

Improve taste

First of all, grinding coffee beans into powder can greatly improve the taste. When we use freshly ground coffee powder to brew, the water can better contact with the particles, so that more substances are dissolved. These substances include organic acids, bitterness, sweetness, etc., which can form a complex and rich taste in the right proportion.

In addition, by adjusting the degree of grinding to different fineness, we can also control the concentration of the brewed coffee. Finer coffee powder will allow water to contact the particles more fully and release more substances in a relatively short time, thus producing a stronger coffee. On the contrary, coarser coffee powder will reduce the contact area between water and particles, release relatively less substances, and produce a weaker coffee.

Release aroma

Secondly, grinding coffee beans into powder can also better release the aroma. Coffee beans contain a large number of volatile compounds, which will be activated and quickly emitted during the grinding process. These aromas are an essential part of the rich coffee we taste.

In addition, freshly ground coffee beans retain more volatile compounds that are gradually released during the brewing process. In contrast, ready-made coffee powder that has been pre-packaged and stored for a period of time often loses many of its aromas due to long-term exposure to air.

Increase nutritional value

The last reason is that grinding coffee beans into powder can increase the nutritional value of coffee. Coffee beans are rich in antioxidants and other beneficial substances, such as caffeine, vitamin B2, and minerals. These substances will be better released during the grinding process and combined with water to form a solution.

By grinding coffee beans into powder, we can extract the maximum amount of these nutrients and make them more easily absorbed by the human body. In contrast, ready-made instant coffee often loses some of its nutritional value due to high temperature processing and long storage time.

Summarize

In summary, grinding coffee beans into powder is an essential step in making delicious coffee. It can improve the taste, release the aroma and increase the nutritional value. So whether you are brewing a cup of delicious coffee at home or in a professional coffee shop, remember to use freshly ground coffee!
