The IBA Negroni names no gin brand. It is 30 ml gin, 30 ml Campari, and 30 ml sweet red vermouth, built on ice. US gin is at least 40% ABV. A 30 ml 40% gin pour is 0.67 NIAAA drinks before Campari and vermouth. This is not a 2023 top-15 tasting.
US Campari tiles conflict 24% vs 25% — read the neck. Related: sweet vermouth for Negroni, Campari vs Aperol, gin.
