Rum is a spirit prepared from sugarcane molasses or juice that has been fermented and then distilled. The clear distillate is typically aged in oak barrels. Most rum is made in the Caribbean (notably in Jamaica and Cuba), North and South American countries, and other sugar-producing areas.
There are many grades of rum. Light rums are often used in cocktails, but “golden” and “dark” rums were traditionally taken straight or plain, frozen (“on the rocks”), or in cooking but are now more regularly mixed.
