Coffee

Coffee is a human beverage, created with ground coffee beans, grown on plants which are native to Earth. The beverage has been widely popular for centuries among humans, primarily because it naturally contains the drug caffeine, which is a stimulant. Coffee is served in numerous restaurants and businesses such as Jim Dandy roadside diners. It is almost always served hot. It is also commonly available on Food & Drink Dispensers which are standard on UNSC military vessels.
