Updated April 2026.
The IBA Negroni already names the vermouth class: 30 ml sweet red vermouth, with 30 ml gin and 30 ml Campari. It does not pick a brand. Sweet vermouth ABV is label-specific — often 15–18% (some rosso bottles print closer to 14.5–15%). The ethanol that dominates is the gin and Campari. This is not a 2023 ranking of ten bottles.
Dry vermouth makes a different drink. Related: sweet vs dry vermouth, Campari vs Aperol, gin for a G&T.
What the card actually uses
| Bottle | IBA role | Typical drinks in 30 ml |
|---|---|---|
| Gin (often 40–47% US) | 30 ml | ~0.68 at 40%; more at 47% |
| Campari | 30 ml bitter | ~0.41 at 24% / ~0.42 at 25% — read the neck |
| Sweet red vermouth | 30 ml | ~0.25–0.30 if 15–18% |
| IBA total (40% gin, 24% Campari, 16% vermouth) | — | ~1.3 |
Four IBA Negronis at that math are a little over five drinks. Fridge the vermouth after opening — it is fortified wine, not whiskey. NIAAA binge pattern is a health line, not a target. No invented MSRP. Pour math: drink math.
