Cuba Libre or Rum and Coke but base rum is Gosling’s Black Seal.
Today, unlike most spirits, Black Seal includes products of both pot stills, as used in fine Cognacs, and continuous stills, as used in grappa. One imparts flavour, the other yields a subtle elegance. Together they work wonders.
Gosling’s Black Seal has a rich, intricate flavour, well balanced and nuanced with butterscotch, vanilla and caramel.
Rum and Coke, or a Cuba Libre[Spanish pronunciation], "Free Cuba" ("free" here is an adjective, not a verb), is a highball cocktail consisting of cola, rum, and traditionally lime juice on ice.
The cocktail originated in the early 20th century in Cuba, after the country won independence in the Spanish–American War. It quickly became popular across Cuba and in many other countries, and has been one of the world's most popular alcoholic drinks. Traditionally, the cola ingredient is Coca-Cola ("Coke"), and the alcohol is a Cuban light rum such as Bacardi. However, the drink may be made with various types of rums and cola brands, and lime juice may or may not be included.
