Origin

History & Origins

The Rum Old-fashioned adapts the venerable Old-fashioned formula, traditionally made with whiskey, to showcase the complex characteristics of aged rum. This variation gained popularity in Caribbean and Latin American bars where local rum traditions formed the foundation of craft cocktails. The drink honors both the original Old-fashioned's simplicity and rum's rich colonial heritage.
