) and Robsta species (Coffea Robusta/Coffea Canephora). There are also some minor species, such as the Liberian species (Coffea Liberica) and the Alabasta species (Coffea Arabusta), but they are rare on the market.

Robusta beans Robusta coffee trees can grow on flat land, it has a strong resistance to disease, and the yield is higher. Compared with Arabica beans, Robusta beans are more round in appearance, with a slightly inflated side with cracks in the middle, and straight grooves reminiscent of soybeans, while Arabica beans are oval and zigzag, a bit like half a peanut.

Generally speaking, Robusta beans are poor in taste, have 2 to 3 times the caffeine content of Arabica beans, and are cheap, mostly for the large coffee industry to produce instant coffee or low-cost comprehensive products. Arabica coffee trees are suitable for growing on fertile hillsides with good drainage at an altitude of about 1,000 to 2,000 meters. The climate should not be too humid, but they still need a continuous rainy season and abundant rainfall. [4]
