A cocktail Negroni in a cut crystal rocks glass with a large ice cube and an orange twist garnish, resting on a polished dark wood bar counter in a dimly lit, classic bar setting.

A Negroni is the definition of a spirit-forward classic: equal parts gin, Campari, and sweet Vermouth, served cold over ice with orange. It looks simple, but small choices (ice, vermouth freshness, stirring time, garnish quality) are the difference between “too bitter” and “perfectly balanced.”


This guide delivers: the official spec, a bartender-proof method, ingredient selection tips, dilution and temperature control, the most common mistakes (and how to fix them), a clear history section that separates fact from legend, plus practical variations that keep the Negroni structure intact.
