Coffee beans refer to the fruits of plants used to make coffee. There are two kinds of coffee beans in the world, Arabica beans and Robusta beans. The fruit of coffee is composed of two oval-shaped seeds facing each other. The side that meets each other is flat, called a flat bean. But there are also round beans, which are composed of around seed, and their taste is not different.
The earliest way for Arabs to eat coffee was to chew the whole fruit (Coffee Cherry) to absorb its juice. Later, they mixed ground coffee beans with animal fat to use as a physical supplement for long-distance travel. It was not until about 1,000 AD that green coffee beans were boiled in boiling water to become an aromatic beverage. After another three centuries, the Arabs began to roast and grind coffee beans. Because drinking is strictly prohibited in the Quran, the Arabs consume a large amount of coffee. Therefore, religion is a big factor that promotes the widespread popularity of coffee in the Arab world.
The Shepherd’s Story
Legend has it that around the tenth century AD, there was a shepherd named Carl on the Ethiopian plateau in Africa. One day he suddenly seemed extremely excited and excited when he saw the goats. He found it very strange, but after careful observation, he found that these sheep were excited after eating some kind of red fruit. Carl tasted some curiously and found that after eating, he felt refreshed and excited, so he picked some of this incredible red fruit and took it home and distributed it to the locals to eat, so its magical effect spread. coming.
According to legend, in the mountains of Yemen in 1258, the chief Sheik Omar, who was deported by his tribe for crimes, was exiled to Vasaba (located in Arabia) far away. When he was exhausted walking on the mountain, he found a branch. After the little bird on its head pecks the fruit on the tree, it makes a very pleasant and tactful cry. So he added water to boil the fruit and drank it, and unexpectedly it gave out a strong and attractive fragrance. After drinking, the original tired feeling disappeared and he was full of vitality. Later, Ouma collected many of these miraculous fruits, and when someone got sick, he made a soup for them to drink, so that they regained their spirits. Because he did good deeds everywhere and was loved by believers, his sins were soon forgiven, and he returned to Mocha and was revered as a holy man because he found this kind of fruit. It is said that the magical medicine at that time was coffee.
The stirring method requires high quality of coffee beans, if you use poor coffee beans, it will amplify its bad flavor. In addition, the stirring and steaming method is more suitable for brewing lightly roasted coffee beans. The grinding degree is often finer, which can increase the soaking area of the coffee powder and improve the extraction rate. However, if you can’t grasp the degree of stirring, it is easy to over-extract. The wide bottom of the pot can provide stronger penetrating power for the injected water flow so that the fine powder can be tumbling for a longer time. This is very important because the release of internal substances is suspended when the coffee powder is tumbling. This avoids prolonged soaking that will cause the unpleasant flavors to be extracted together. For medium-to-light roasted coffee beans, during the brewing process, the coffee powder spends more time on the water surface, and the water resistance from the filter cup becomes more resistant. Large, to better control the extraction time; for the selection on the filter bowl, it is recommended to use a filter bowl with a faster flow rate design.
Children: Many nutritionists abroad have confirmed that children are the most unsuitable people to consume coffee beans.
