In nature we have are more than 80 different species of coffee, but only four are used to be marketed.
Is the best-quality coffee, probably originated in Ethiopia, this kind of coffee has a low content of caffeine and that is produced worldwide. Is grown mainly in South America but also in Asia and Africa. Among the best known variety we find: Moka, Bourbon, Maragogype, Caturla, Mundo Novo, Nacional.
Also known as Robusta is the original central Africa coffee; is just below the quality Arabica, but grows faster and contain more caffeine. This quality makes up a quarter of the entire world coffee production.
From the forests of Costa d'oro, grows in tropical and subtropical zones, but due to variability of the quality the production is grown increasingly rare.
This species has a performance very variable so it's more diffucult to commercialize; looks very similar to Robusta for its seeds and size and to Liberica for leaves and growth.
