What Do You Add To Guinness To Make A Black Velvet?

A black velvet is traditionally made by adding a white sparkling wine to Guinness.
A tall flute glass is filled halfway with chilled Guinness, which is then topped with the sparkling wine. Both liquids have different densities, which is why they remain in largely separate layers. Whatever the top layer is, the best way to make the mixture is by pouring it over a spoon, held upside down over the glass. This causes the liquid to fill gently, running down the sides, rather than splashing into and mixing with the lower layer.

Black Velvet, is also known as a Bismarck. The black velvet cocktail was a favorite with Otto von Bismarck, who drank it by the gallon, according to 'Brewer's Dictionary of Phrase and Fable', which is why in Germany the drink often goes under his name. The drink's origins can be traced back to London in 1861, when it was served at Brooks's Club, during the nation's mourning the death of Queen Victoria's Prince Consort, Prince Albert.
