Boulevardier

This one has been in the cocktail books long enough to read as an old relative of the Negroni rather than a modern stunt. Gin out, whiskey in, and it turns warm and rounded where the Classic was bright and dry. Bourbon leans sweet and full, rye pushes back drier and spicier, and the vermouth matters as much as the whiskey: Antica plush, Punt e Mes with grip. It's where you go once the Classic feels familiar and you want more weight. Let everything lean rich at once, bourbon under a heavy vermouth, and the bitter loses its footing.
