Coffee is prepared from roasted seeds of coffee plants, which are cultivated in over 70 countries worldwide, though it originated in Ethiopia. The two most common coffee plant varieties are Coffea arabica and Coffea canephora. Coffee spread from Ethiopia to the Middle East, Turkey, and Italy, and the first coffeehouse opened in Italy in 1645. Coffee is now a vital cash crop for many developing nations and popular coffee drinks include espresso, Americano, cappuccino, and lattes.
