When craft cocktailing first took flight in the United States, one of the nation’s leading bars (the Violet Hour in Chicago) posted a screed of “house rules” throughout its dimly lit speakeasy. Besides outlawing baseball hats and cellphone use, the newfangled temple of hooch defined drinks it (justifiably) prohibitedโ€”Jรคger bombs, light beer, Grey Goose. Punctuating the blacklist was a fan favorite: “No Cosmopolitans,” it scornfully read.

It was a stuffy rebel yell, declaring war on a sugar-rush drinking culture that for decades ruled bars with a sticky fist. Noses turned up at populist cocktails like the cosmopolitan and dirty martini, deeming them unfit for the refined palates of guys with complicated facial hair.

But as old-timey mustaches untwist and high-end cocktail joints aim to be more approachable, bartenders are refurbishing the passรฉ drinks they once spurned.
