What kind of coffee do you know?

Coffee is called coffea in the biological genus. This genus is a member of the Rubiaceae family. It has more than 500 species and more than 6000 species, most of which are tropical trees and shrubs.

From the point of view of drinkers, coffee trees can be roughly divided into five types, of which Arabica and Robusta are more common.

Arabica species, which account for more than 70% of the world's total output, are generally grown on slopes above 900 meters above sea level and are mostly found in tropical high-altitude areas such as Central and South America, East Africa, Southeast Asia and Hawaii. Corresponding to its pleasant aroma and rich taste, the tree needs more manual care, and it also requires higher stability of temperature and humidity in the climate, so the price is naturally more expensive. Arabica is divided into many varieties, including the ancient Bourbon, and some other excellent varieties, such as Catuna, Catuai, Typica and so on. The above varieties are generally adopted in most planting countries, of course, they may be purebred, crossbred or mixed-that is, different varieties will be planted in one manor and then blended together after picking. In order to increase the complexity of coffee flavor. But there are some exceptions. Sumatra grows the endemic Sumatran species (Sumatra), while ancient growing countries like Ethiopia have their own unique and traditional varieties.

Robaxter, which is more adaptable to the environment, tastes mediocre and bitter, and more importantly, its caffeine content is 2 to 3 times higher than that of Arabica. Generally grow on the slope of 200 to 600 meters above sea level, the requirement of manual care is very low, the price is low, and it is mostly used for canned and instant coffee.
