El Presidente

The El Presidente is a Cuban cocktail made of rum, orange curaçao, vermouth, and grenadine. The original recipe calls for blanc vermouth. Some believe it is the only bona fide classic cocktail that is supposed to use harder to find blanc vermouth and is frequently mismade with dry vermouth. While variations are made using other orange liqueurs than curaçao, the drink is traditionally meant to be red in color, so blue curaçao should not be used. The red comes from red curaçao,[citation needed] or when paler colors are used, from the grenadine. The El Presidente earned its acclaim in Havana during the 1920s through the 1940s during the American Prohibition. It quickly became the preferred drink of the Cuban upper class.
