Rum is a distilled beverage made from sugarcane by-products such as molasses and sugarcane juice by a process of fermentation and distillation. The distillate, a clear liquid, is then usually aged in oak and other casks. While there are rum producers in places such as Australia, India, Reunion Island, and elsewhere around the world, the majority of rum production occurs in and around the Caribbean and along the Demerara river in South America. Some major rum brands include Abuelo, Bacardi, Barbancourt, Brugal, Captain Morgan, Appleton Estate, Havana Club, Stroh, Matusalem, Mount Gay, Bundaberg, Myers, Malibu Rum, Gosling's, Cruzan, Pusser's, Flor de CaÃ±a, Don Q, and Ron Zacapa Centenario. Rum is produced in a variety of styles. Light rums are commonly used in mixed drinks, while golden and dark rums are appropriate for use in cooking as well as cocktails. Premium brands of rum are also available that are made to be consumed neat or on the rocks. Rum plays a part in the culture of most islands of the West Indies, and has famous associations with the British Royal Navy and piracy. Rum has also served as a popular medium of exchange that helped to promote slavery along with providing economic instigation for Australia's Rum Rebellion and the American Revolution.
