Rum is distilled from sugarcane byproducts like sugarcane juice, syrup, and molasses. It originated in Caribbean sugar plantations in the 17th century, where slaves distilled it. There are several styles - Puerto Rican rum is light-bodied and dry, distilled in a patent still. Jamaican rum is rich, full-bodied, and distilled in a pot still. Rum is used in mixed drinks and cocktails as well as flambéing desserts. Popular brands include Bacardi, Captain Morgan, and Appleton.
