Cunard, The Savoy and Jack Daniel’s have come together to create a one-of-a-kind cocktail named Age of Discovery. The cocktail, all 300 liters of it, has been loaded aboard the Queen Mary 2, where it will mature inside a specially chosen Jack Daniel’s barrel for the entirety of the ship’s four-month World Voyage, visiting five continents. Daniel Baernreuther, assistant food and beverage director, The Savoy, handpicked the barrel at the Jack Daniel Distillery in Lynchburg, Tenn.

The cocktail includes a mixture of Savoy Select Jack Daniel’s Single Barrel, Jack Daniel’s Old No. 7, Bacardi 9, Spice Trail Madeira, Dubonnet, Martini Riserva Rubino, Earl Grey and cocoa nib bitters. The mixologists at The Savoy Beaufort Bar designed the drink. Once aboard the ship, the barrel will be secured on the open deck, where it will be exposed to inclement weather, varying temperatures and sunlight, which will further produce a cocktail flavor like no other.

“The Jack Daniel’s and Bacardi represent the discovery of the Americas, while the Dubonnet is there as a symbol of Cunard’s royal associations. The spice-infused Madeira, used to sweeten the cocktail, is synonymous with the famous spice trail and oceanic expeditions and was known to be a favorite beverage of Queen Elizabeth The Queen Mother and Queen Elizabeth II,” said Niel Donachie, Beaufort Bar.

When the voyage ends May 10, the barrel will be shipped to a bottling plant in West Dunbartonshire, where it will become a member of The Savoy Collection, one of the most unique collections of luxury spirits in the world. While this finite mixture will definitely be coveted, an un-aged blend of the same ingredients is now available at the Beaufort Bar.

For the curious, an Age of Discovery social media account will track the barrel’s progress and the 39 destinations visited.
