Three kinds of coffee beans with the best quality in the world

1. Arabica coffee tree

The country of origin is Ethiopia, and its coffee bean production accounts for 70% of the world's output; the world-famous Blue Mountain Garffin, mocha coffee and so on are almost all Arabica species. Arabica coffee trees are suitable for growing in high mountains with large temperature difference between day and night, as well as low humidity and well-drained soil; the ideal altitude is 2000 meters, the higher the altitude, the better the quality. Arabica coffee trees require fertile soil, sufficient moisture, proper sunshine and shade, poor resistance to diseases and insect pests, and low annual output per unit area.

2. Robsta Coffee Tree

Congo, which originated in Africa, accounts for about 20% of the world's output. 30%. The Robusta coffee tree is suitable for planting in the lowlands below 500 meters above sea level, has a strong adaptability to the outside world, can resist adverse weather and insect pests, and does not need much manual care during soil preparation, weeding and pruning, and can be allowed to grow in the wild. It is a kind of coffee tree that is easy to cultivate. But its flavor is more bitter than Arabica, and its quality is much lower, so it is mostly used to make instant coffee. In general, the coffee sold in fast food restaurants mainly uses Robusta coffee beans as the material. Because it is made in Africa, most Africans drink robusta coffee. Robusta coffee trees have strong resistance to diseases and insect pests and are not vulnerable to agricultural diseases. the annual output of coffee trees per unit area is higher and can be harvested in large quantities by machine. generally speaking, the production cost is lower than that of Arabica coffee.

3. Liberian coffee trees

Liberia, which is native to Africa, has a shorter cultivation history than the other two coffee trees, so it is only planted in a few places such as Liberia, Surinam and Gaiana, so it accounts for less than 5% of the world's output. The coffee tree of Liberia is suitable for planting in the lowlands, and the coffee beans produced have a strong aroma and bitter taste.
