The term coffee is said to derive from Kaffa, the ancient name from part of the present day Southern Nations, Nationalities and Peoples' State where Bonga lies. The story goes that sometime around the 6th century in forests near Bonga, a goat herder named Kaldi spotted his animals getting frisky after eating red berries from a shrub he'd never seen before. So Kaldi gave the berries a try himself and the coffee bean was discovered.
