How many standard drinks are in a Martini?
Gin (or vodka) and dry vermouth, stirred.
A cocktail's strength is the sum of the alcohol in each ingredient, not just one pour. Based on a typical recipe, a Martini contains about 1.09 fl oz of pure alcohol — roughly 1.8 standard drinks.

| Total | 3 oz | 36.3% | 1.8 |
One US standard drink is 0.6 fl oz of pure alcohol. A heavier pour or a stronger recipe pushes the number up fast — see what counts as a standard drink or the standard drink calculator to check your own.
