| Arabica coffee for its high quality considered among the best coffees. Probably originating in Ethiopia this species contains little caffeine and is the most traded of all coffees. It's farmed especially in South America but also in Asia and Africa. Among the most famous and appreciated types are: Moka, Burbon, Maragogype, Caturla, Mundo Novo, and Nacional.

| Coffea Canephora, also called Robusta, originating from Central Africa is of lower quality but grows more rapidly and as the name suggests is more resilient that others. The presence of caffeine in Robusta is much higher than in Arabica. Robusta represents one quarter of the world-traded production of coffee.
