The drink was first made by a bartender of Brooks's Club in London in 1861 to mourn the death of Prince Albert, Queen Victoria's Prince Consort. It is supposed to symbolize the black armbands worn by mourners. It was said that “even the champagne should be in mourning.” Today, the drink is not exclusive to mourning.
