Coffee Arabica is a species of coffee originally indigenous to the mountains of Yemen in the Arabian Peninsula, hence its name, and also from the south western highlands of Ethiopia and south eastern Sudan. It is also known as the "coffee shrub of Arabia", "mountain coffee" or "Arabica coffee". Coffee Arabica is believed to be the first species of coffee to be cultivated, being grown in southwest Arabia for well over 1,000 years. It is considered to produce better coffee than the other major commercially grown coffee species, Coffee canephora (Robusta). Arabica contains less caffeine than any other commercially cultivated species of coffee
Coffee canephora (Robusta Coffee) is a species of coffee which has its origins in central and western sub-Saharan Africa. It is grown mostly in Africa and Brazil, where it is often called Conillon. It is also grown in Southeast Asia where French colonists introduced it in the late 19th century. In recent years Vietnam, which only produces Robusta, has surpassed Brazil, India, and Indonesia to become the world's single largest exporter. Approximately one-third of the coffee produced in the world is Robusta. Canephora is easier to care for than the other major species of coffee, Coffee Arabica, and, because of this, is cheaper to produce. Since Arabica beans are often considered superior, Robusta is usually limited to use as a filler in lower-grade coffee blends. It is also often included in instant coffee, and in espresso blends to promote the formation of "crema". Robusta has about twice as much caffeine as Arabica.
