Coffee is a plant that originated on the African continent, in the high regions of Ethiopia (Cafa and Enaria), where it occurs spontaneously as an understory plant. The Cafa region may be responsible for the name coffee. According to one of the "legends" of the discovery of the coffee tree, an Ethiopian shepherd was the one who noticed that some of his goats changed their behavior after using leaves of the coffee plant in their feed, influencing the behavior of monks who observed him.
