Spirit Proofing
Calculator
Enter current volume and strength, then your target ABV. The calculator estimates final theoretical volume and water required.
WATER REQUIRED75 L
FINAL VOLUME175 L
Assumptions
ABV is entered as a percentage. The result conserves pure alcohol and treats volumes as additive; it does not correct for contraction or temperature.
How the calculation works
The calculator uses conservation of pure alcohol: current volume × current ABV = final volume × target ABV. Water required is the difference between final and current volume.
