According to one legend, ancestors of today's Oromo people in a region of Kaffa in Ethiopia were the first to recognize the energizing effect of the coffee plant. However, no direct evidence that has been found earlier than the 15th century indicating who among the African populations used it as a stimulant, or where coffee was first cultivated.
Coffee is a brewed drink prepared from roasted coffee beans, the seeds of berries from certain Coffea species. When coffee berries turn from green to bright red in color – indicating ripeness – they are picked, processed, and dried. Dried coffee seeds (referred to as "beans") are roasted to varying degrees, depending on the desired flavor. Roasted beans are ground and then brewed with near-boiling water to produce the beverage known as coffee. There are two main types: Arabica and Robusta. Growers predominantly plant the Arabika species. Although less popular, Robusta tastes slightly more bitter and contains more caffeine.
