Coffee is a brewed drink made from roasted coffee beans, which come from the Coffea plant native to Africa. The two most commonly grown coffee plant varieties are arabica and robusta. Coffee beans are picked, processed, dried, and roasted. They are then ground and brewed to produce coffee. Coffee contains caffeine and can have a stimulating effect. It is one of the most popular drinks worldwide and can be prepared and presented in many ways. Coffee cultivation began in Abyssinia and its consumption later spread globally. Coffee is a major agricultural export for many countries.
