The IBA Margarita is 50 ml of 100% agave tequila, 20 ml triple sec, and 15 ml fresh lime. Blanco (plata / silver) is the CRT class that is unaged or only briefly rested — the usual mixer. Most US blancos print 40% ABV, so that 50 ml pour is about 1.13 NIAAA drinks before the liqueur. A US 1.5-ounce house pour is one drink. This is not a 2022 tasting of ten bottles.
Gold mixto plus caramel is a different Margarita. Related: tequila for margaritas, margarita alcohol, Cointreau vs Grand Marnier.
What the shaker actually needs
| Part | Spec |
|---|---|
| IBA tequila | 50 ml 100% agave — typically blanco |
| Triple sec | 20 ml. Cointreau US is 40%; generic triple sec 15–40% |
| Lime | 15 ml fresh. 0.0% ABV |
| 40% tequila drinks | ~1.13 from 50 ml; 1.00 from 1.5 oz |
| Skip as “the blanco pick” | Mixto gold labeled only “tequila” |
Four IBA Margaritas are about 4.5 drinks from the tequila plus the triple sec. NIAAA binge pattern is a health line, not a target. No invented MSRP. Pour math: margarita drinks.
