Rum originated in the 17th century when slaves in the Caribbean discovered they could ferment and distill molasses, a byproduct of sugar production, into alcohol. Rum went on to play a major role in Atlantic trade for centuries. There are several types of rum defined by production methods and aging, including light/silver rum, gold rum, dark rum, spiced rum, and flavored rum. Rum is generally produced by fermenting and distilling sugarcane molasses but varies in flavor depending on aging and blending processes.
