The Black Velvet

Legend has it that the drink originated in London’s Brooks Club in 1861, created on the occasion of Prince Albert’s death. England was in national mourning after prince Albert and the bartender thaught that the champagne should also 'wear' black. He then combined it with the dark Guinness. This cocktail was in the old days served in a beer glass but nowadays a champagne flute is often used.
A Black Velvet consists of equal amounts of Guinness Stout and champagne, although there are recipes that call for three or four parts of champagne to one part beer.
