Elaraby, the three original species of coffee trees, is a coffee variety.

Everyone should have heard of the coffee variety "Elaraby". The best quality beans of the famous Colombian coffee are all Elaraby varieties. When it comes to the variety of coffee, we must first understand the type of coffee tree. At present, the most important coffee beans in the world mainly come from Arabica, Robata and Liberia. these three varieties of coffee beans are the three original species of coffee trees, and the quality of coffee beans produced by other coffee trees is also higher than that of other coffee trees.

The Arabica coffee tree, which originated in Ethiopia, accounts for 70% of the world's output of coffee beans; the world-famous blue mountain caffeine, 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, and ten soils with low humidity and good drainage; the ideal altitude is 500m ~ 2000, the higher the altitude, the better the quality. However, due to the weak ability to resist diseases and insect pests, it is more difficult to grow than the other two coffee trees.

The Robastian coffee tree, which originated in the Congo in Africa, accounts for about 20% to 30% of the world's production. Luoba Jinta 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 bad weather, resist diseases and insect pests, and is in soil preparation. Weeding and pruning do not require much manual care, 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 is mainly made of coffee beans grown in Robasta. Because it is made in Africa, most Africans drink robastian coffee.

The Liberian coffee tree is native to Liberia in Africa, and its cultivation history is shorter than that of the other two coffee trees, so it is limited to a few places such as Liberia, Suriname 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.
