Stirring over ice adds roughly 20–25% water.
90 ml ≈ 3 oz, a typical stirred cocktail before dilution.

Dilution varies with ice size, temperature, and how long you mix; the percentage is an average, not a law.
About Cocktail Dilution Calculator
Ice doesn't just chill a drink — stirring adds roughly 20–25% water and shaking 25–30%, which is a deliberate part of the recipe. Enter a drink's pre-dilution volume and ABV to see the final volume, final strength, and exactly how much water the mixing added.
Batch mode scales a recipe to any number of servings and tells you how much water to add up front, so bottled or pitcher cocktails taste like they came off the bar spoon instead of tasting hot and underdiluted.
Common uses
- Pre-batch Manhattans for a party with the right pre-dilution water
- Check the real ABV of a shaken drink before pouring a second
- Tune a stirred recipe that tastes too strong straight from the mixing glass
Example
Input
Batch · 8 servings × 90 ml at 30% · stirred (22%)
Output
720 ml spirits + 158 ml water · final ABV 24.6%
Limitations
- Dilution percentages are averages — ice size, temperature, and mixing time all move them.
- Built drinks are treated as zero mixing dilution; ice melting in the glass afterward isn't modeled.
