Boulevardier
The boulevardier cocktail is an alcoholic drink composed of whiskey, sweet vermouth, and Campari. It originated as an obscure cocktail in late 1920s Paris, and was largely forgotten for 80 years, before being rediscovered in the late 2000s as part of the craft cocktail movement, rapidly rising in popularity in the 2010s as a variant of the negroni, and becoming an IBA official cocktail in 2020. The boulevardier first appeared in print in the Parisian cocktail book Barflies and Cocktails , where it is ascribed to Erskine Gwynne, an American-born writer who founded a monthly magazine in Paris called Boulevardier, which appeared from 1927 to 1932.[a] The cocktail appears, not in the main list of recipes, but in the essay "Cocktails About Town" by Arthur Moss, which describes cocktails by men-about-town. The boulevardier is described as an equal parts cocktail:
