Rum originated from sugarcane-based spirits produced in the 17th century British West Indies. Sugarcane juice is extracted and boiled to produce molasses, a byproduct of sugar production. Molasses is fermented with yeast to produce a wash, then distilled to produce rum. Rum is classified as light-bodied or full-bodied depending on whether it is distilled in a column still or pot still. Rum is then aged in oak barrels, imparting color and flavor. Major rum-producing regions include Puerto Rico, Jamaica, Barbados, Cuba, Guadeloupe, Haiti, and Guyana, each with distinct rum styles.
