Cocktail ABV Calculator
Strength of a mixed drink with dilution, standard drinks and units.
About this tool
Add each ingredient with its volume and ABV (mixers at 0%), choose how the drink is made, and see the final ABV, volume, pure alcohol, US standard drinks and UK units.
How strong is a cocktail?
A cocktail's ABV is the total pure alcohol divided by the final volume, and the final volume includes the water from melting ice. That's why the method matters: stirring with ice typically adds about 20โ25% water, shaking 25โ30%, building over ice around 15% and blending more. The alcohol in each ingredient is its volume ร its ABV. A Negroni of 30 ml each of gin (40%), Campari (25%) and sweet vermouth (16%) contains 12 + 7.5 + 4.8 = 24.3 ml of alcohol in 90 ml, 27% before dilution and about 22% once stirred. That's about 1.4 US standard drinks (14 g of alcohol each) or 2.4 UK units (10 ml or 8 g each). Bartenders use this to balance recipes and write menus, and drinkers can use it to pace themselves: a spirit-forward cocktail often holds as much alcohol as two beers. Honest limits: dilution varies with ice size, temperature and technique, and liqueur and vermouth strengths vary by brand, so check the bottles. This is an estimate of a drink's strength, not of how intoxicated anyone will be. Drink responsibly, and never drink and drive. The ABV calculator and the party food calculator are related.
Frequently asked questions
How do I calculate the ABV of a cocktail?
Add up each ingredient's volume ร ABV to get the pure alcohol, then divide by the final volume including dilution.
How much does ice dilute a cocktail?
Typically about 20 to 25% when stirred and 25 to 30% when shaken.
What is a US standard drink?
14 g of pure alcohol, about 17.7 ml, equal to a 1.5 oz shot of 40% spirit.
What is a UK unit of alcohol?
