Coffee was born in Ethiopia when a shepherd noticed his goats jumping around wildly after eating coffee berries. Or so the story goes. What is certain is that the word coffee comes from Kaffa, a region in Ethiopia. The leaves and dried berries were initially infused in hot water in a similar way to tea. It was only later, when coffee reached the Ottoman Empire, that it was prepared in a way we would recognise today. Great Inventions explores all aspects of coffee growing and appreciation.
