WHO DISCOVERED COFFEE?

Legend says that coffee was discovered in Ethiopia when goatherds noticed their flocks stayed awake all night after feeding on coffee leaves and berries.

Coffee reached Arabia in the 1200s where it was used as a beverage for the first time. Before that time it had been used as a food, then as a wine and next as a medicine.

During the 1500s coffee moved from Arabia to Turkey and then to Italy. In the early 1600s coffee houses appeared throughout Europe. Coffee came to America in the 1600s and was introduced in Brazil in the 1700s.

The world's current top 10 coffee growing countries (starting with the leader): Brazil, Columbia, Ivory Coast, Angola, Mexico, Uganda, E1 Salvador, Indonesia, Ethiopia and Guatemala.
