Rich aroma, the king of coffee beans!

Coffee, as a popular drink, is famous for its rich aroma. It comes from coffee beans and is known as the "king of coffee beans".

First, let's learn about the origin and history of coffee beans. It is said that the first person to discover coffee was Kaldi, an Ethiopian shepherd. He found that his sheep became unusually active after eating certain red berries. So he tried to boil these berries and drink them. This is the story of the birth of the first cup of coffee.

Over time, people began to notice the benefits that coffee brought to their physical and mental health, and as a result, it became popular in the Arab world and gradually spread to other places.

Next, let's take a closer look at how the intoxicating aroma is produced. First, after picking the ripe fruits, farmers will dry them and remove the shells to get the substance called "mung beans" in its original form.

Then, the "green beans" go through a roasting process, where temperature and time are key factors. During the roasting process, the coffee beans undergo chemical reactions, producing a variety of complex aroma substances. These aroma substances will vary with the degree of roasting.

Finally, when brewing coffee, we can adjust the taste of the coffee by choosing different grind sizes, water temperatures, and brewing times. These factors will affect the final cup of coffee that is full of fragrance.

In summary, coffee beans, as the king of beverages, have played an important role in the long history. They originated in Ethiopia and gradually spread all over the world. Their strong flavor is produced by the combined effects of multiple links such as picking, processing and brewing.
