Bacardi and Coke, or rum and Coke, is one of the most common cocktails served, alongside Jack and Coke, and vodka and soda. A brilliantly simple drink, the rum and coke is actually a simplification of a classic cocktail called the Cuba Libre which dates back to the Spanish American War. During the war Americans packed their ships with Coca-Cola because the traditionally stimulating qualities of the original formula helped in the fight.
