Coffea arabica (/əˈræbɪkə/), also known as the Arabian coffee, "coffee shrub of Arabia", "mountain coffee" or "arabica coffee", is a species of Coffea. It is believed to be the first species of coffee to be cultivated, and is the dominant cultivar, representing about 60% of global production. Coffee produced from the (less acidic, more bitter, and more highly caffeinated) robusta bean (C. canephora) makes up most of the remaining coffee production. Arabica coffee was first found in Yemen and documented by the 12th century. Coffea arabica is called būna in Arabic.
