To learn the theoretical knowledge of coffee beans, coffee colleges open cafes to learn coffee blending.

Boutique coffee is fresh coffee. Whether it's food or drink, of course, the fresh the better, and so is boutique coffee. High-quality coffee should keep the coffee beans fresh before making, including the preservation of baked beans, and grind the coffee beans into powder before making, which is also to retain its original and best flavor. The way of making hand-brewed coffee is such a way to make high-quality coffee, and it is also one of the coffee-making methods that can best retain the original flavor of coffee. Boutique coffee is good coffee and is harmless to health. Different from coffee made with low-quality coffee beans, high-quality coffee uses high-quality coffee beans and freshly made coffee, which is harmless to health, and drinking in moderation is beneficial to the body and mind.

Arabica is just a big division of the coffee tree pedigree. When it comes to the coffee tree pedigree, it is as long and complex as the genealogy, and the coffee beans produced by each different coffee tree have its own special flavor.

At present, the three most important and productive coffee trees in the world are genealogies: Arabica, Robusta and Liberika. Among them, Arabica has the largest output in the world, and the flavor of Arabica is the most elegant among the three categories, followed by Robusta, whose classic flavor is smelly rubber. But Robsta is an important raw material for commercial coffee because of its low price and excellent disease resistance, among which instant coffee is the most commonly used. The third category of Liberika must not have been heard of by many friends, and many friends must have drunk it, the most important representative of which is Malaysian "white coffee". Liberika is famous for its fishy smell.

But everyone must be very strange, I drank instant coffee and white coffee are very delicious ah, there will not be such a disgusting taste ah! Indeed, for commercial purposes, businesses have to add a large amount of cream and sugar to instant coffee to dilute the taste of their original coffee has achieved their commercial purpose. Arabica species, although it is a delicious variety, can not have both. Although Arabica species have elegant taste, they have poor disease resistance and climate adaptability. The fruit of most Arabica species is significantly smaller than that of Robusta species. Arabica species must grow in tropical plateaus, require a large temperature difference between day and night, cool and stable temperatures throughout the year, and are more susceptible to diseases and insect pests, which is the biggest reason why it is difficult for Arabica species to grow. Growing Arabica coffee requires both the right climate and meticulous care, which leads to the high price of Arabica coffee beans among all other varieties.

Arabica has evolved dozens of varieties in its long evolution, but at first, they all came from the two oldest varieties, namely Tibica and Bourbon.

Arabica took root in Ethiopia in the seventh century, and then until the ninth century, for two hundred years, Arabica was transplanted to present-day Yemen with the national war between the Aksum Empire and the Arabian Peninsula. Two different forms of Arabica have also taken root in Yemen.

One of them, the top young leaves are ancient bronze brown, the tree is tall, the leaves are narrow, and the beans look long, which is what we call Typica.

Another variety, the top young leaves are turquoise (green top), the leaves are wide, the bean is short round, this is what we call Bourbon.

Tibika and bourbon are regarded as excellent varieties of ancient times, famous for their elegant taste and strong fruit aroma, and both belong to the most valuable boutique coffee trees in the world today, but they are the oldest varieties, so they have poor weather tolerance and disease tolerance, so it is difficult to grow widely.

It is true that pure iron is rarer than cards in Chinese mainland. If you want to feel the taste of Tibica, you can try to use Yega Xuefei as a standard. It can be said that Yega Xuefei contains the most Tibica because it is produced in Ethiopia. Bourbon varieties, bourbon varieties are mainly monopolized by Europe and the United States, especially in the Chinese mainland region, but it is said that Bourbon is named after the French Bourbon family, which loves this variety of coffee very much. this has led to the flow of a large number of bourbon varieties to Europe, especially France. Therefore, it is normal that Asian countries have no chance to drink down this variety.
