Boulevardier is a classic cocktail made with whiskey, Campari, and sweet vermouth. It has a bittersweet and complex flavor profile.
Boulevardier recipe
Pour all ingredients into mixing glass with ice cubes. Stir well. Strain into a chilled cocktail glass.

The Boulevardier is often described as a whiskey Negroni, but it has its own personality. It is rich, bittersweet, and silky, with dark fruit and herbal notes from the vermouth and a firm orange-red bitterness from Campari. Bourbon brings caramel and vanilla; rye shifts the drink toward spice, structure, and a slightly leaner finish.
Serve it straight up and very cold. Because there is no ice in the glass, temperature matters more than people think: a warm glass makes the drink feel heavier and sweeter. This is an excellent pre-dinner cocktail, but it also works after dinner for drinkers who enjoy bitter profiles. If you want a softer expression, choose a plush sweet vermouth and bourbon; for a more assertive one, go with rye and a more herbal vermouth.
The Boulevardier dates to the 1920s and is most commonly linked to Barflies and Cocktails, a 1927 book by Harry McElhone of Harry’s New York Bar in Paris. It is usually associated with Erskine Gwynne, an American writer in Paris who published a magazine called Boulevardier. Exact origin details are not perfectly documented, but that connection is the most widely accepted.
For a non-alcoholic version, stir together a zero-proof whiskey alternative, a bitter Italian-style aperitif substitute, and a non-alcoholic sweet vermouth-style aperitif over ice, then strain into a chilled glass. Keep the same proportions and finish with an orange twist. The result will not be identical, but it can still deliver the drink’s signature bittersweet, citrus-herbal shape.
