The Muslims were the first to develop coffee.
As early as 1524 they were using it as a replacement for the wine they were forbidden to drink.
According to legend, an astute Arab herder noticed that his goats became skittish after chewing on the berries of a certain bush, so he sampled a few himself and found them to be invigorating.
The region of Abyssinia where this took place is named Kaffa, which gave us the name for the drink we call coffee.
