Christopher Columbus never had an espresso, a latte or a double, skinny mochaccino grande. When he set sail from Spain in 1492, coffee was an exotic luxury available only in the Muslim world. Five hundred years later, it is the second most valuable legal export on earth and the most widely used psychoactive drug. This program looks at the discovery of coffee in Ethiopia, its ability to control the economy of major nations, and its role in both the American and French Revolutions. We'll find out how it is grown and processed, the truth about decaffeination, and how to make a perfect cup of Joe.
