Calculate water addition to dilute spirits to target proof or ABV. Barrel-proof bottling and proofing calculator for distillers.
Calculate number of bottles from batch volume for wine, beer, and spirits. Standard 750ml, 375ml, and 1L bottle yields with loss allowance.
Calculate SO2 and potassium metabisulfite additions for winemaking. Free and total sulfur dioxide dosing by pH and volume.
For blending high and low ABV liquids to target: parts of high = (target − low), parts of low = (high − target).
Ratio = (Target − Low ABV) : (High ABV − Target)Multiply each component volume by its ABV, sum, divide by total volume for final blend ABV verification.
Final ABV = Σ(Volume × ABV) ÷ Total volumeCalculate exact volume of high-ABV component needed to reach target in a fixed total batch volume.

Mix 14.5% wine with 12% wine to target 13.5%: ratio 1.5:2.5 or 3 parts high to 5 parts low.
Blend 40% spirit with juice (0% ABV): need 375 ml spirit + 625 ml juice for 15% ABV batch.
Blend 130 proof (65% ABV) bourbon with 100 proof (50% ABV) to achieve 57% ABV bottling strength.
Blending liquids of different alcohol by volume (ABV) concentrations requires weighted average calculation. Enter volumes and ABV of source liquids and target ABV to calculate exact blend ratios for winemaking, spirits blending, and batch production.
