The Mocha coffee bean is a variety of coffee bean originally from Mocha, Yemen. It is harvested from the coffee-plant species Coffea arabica, which is native to Yemen. In appearance it is very small, hard, round with an irregular shape, and olive green to pale yellow in colour. The Mocha coffee bean has a distinct flavor. Due to the similar name, it is sometimes confused with a chocolate-flavored coffee. Although the beans originally shipped from the port of Mocha, Yemen were thought to have had a chocolate-like taste, current mocha beans from Yemen do not.
