How Alcohol Dilution Works
This calculator uses the dilution formula to determine how much water to add to achieve your desired alcohol strength:
Water to Add = (Current Strength × Current Volume) / Desired Strength - Current Volume
Key Concepts:
- ABV: Alcohol by Volume - percentage of alcohol in the total volume
- Proof: Twice the ABV percentage (e.g., 40% ABV = 80 proof)
- Dilution: Adding water to reduce alcohol concentration
Common Uses:
- Diluting high-proof spirits for cocktails
- Adjusting homemade liqueurs
- Preparing tinctures and extracts
- Creating flavored spirits
Pro Tips
- • Always add alcohol to water, never water to alcohol
- • Use distilled water for best results
- • Allow the mixture to rest for 24 hours before using
- • Taste test small amounts before diluting large volumes
- • Keep track of your dilution ratios for future reference
