What is the typical weight of an alcohol shot?

How much does a “shot” of alcohol weigh?

A standard “shot” is usually measured by volume, not weight. In the US, one standard shot is typically about 1.5 fluid ounces (44 mL). Alcohol weight depends on the drink’s alcohol concentration, because ethanol is denser than water.

For a typical 80-proof liquor (40% alcohol by volume), the full shot’s weight is usually around:
- About 40–45 grams per 1.5 fl oz shot (roughly 1.5 ounces ≈ 43 mL, with the mixture weighing in that range)

What if the shot is 1 oz instead of 1.5 oz?

Many people mean different pour sizes. If your “shot” is 1.0 fl oz (30 mL) of 80-proof liquor, the weight is commonly around:
- About 25–30 grams

Why weight varies from bar to bar

Weight changes with:
- Pour size (1 oz, 1.5 oz, etc.)
- Proof/alcohol percentage (vodka, whiskey, rum, etc. vary)
- Soda/mix-ins (a “shot” plus anything added won’t weigh the same as straight liquor)
