Find how much water to add to reach a target alcohol percentage.
Dilution adds enough water so the absolute alcohol stays constant while the total volume rises to the target percentage. Getting the added water right keeps flavor intensity predictable whether proofing down a spirit or tweaking a batch drink.
Alcohol Dilution
Water = volume x (ABV - target) / target
Water = volume x (ABV - target) / target Dilution adds enough water so the absolute alcohol stays constant while the total volume rises to the target percentage.
