What primary ingredient is used to make rum?

The primary ingredient used to make rum is sugar cane. Unlike many other spirits that are distilled from grains or potatoes, rum specifically derives its sweetness and character from sugarcane or its byproducts, such as molasses. The fermentation process of sugar cane creates alcohol, which is then distilled to produce rum. This distinctive source gives rum its unique flavor profile, often characterized by sweetness and a range of fruity and caramel notes, depending on the distillation method and aging process.

Barley, wheat, and potatoes are used to make other types of spirits such as whiskey and vodka respectively, but they do not play a role in rum production. This crucial difference highlights why sugar cane is the correct primary ingredient in the making of rum.
