where did coffee originate

Coffee originated in Ethiopia. According to legend, it was discovered around the 9th century by an Ethiopian goat herder named Kaldi, who noticed his goats becoming energized after eating berries from a certain tree. The use of coffee berries then spread within Ethiopia, where local tribes even mixed the beans with animal fat for energy. Coffee was later cultivated and brewed in the Arabian Peninsula, particularly Yemen, by the 15th century, from where it spread to the Ottoman Empire and beyond, becoming a global beverage.
