Professional ABV correction and dilution calculations using OIML standards
Temperature Correction: Uses OIML (International Organization of Legal Metrology) standards for alcohol temperature correction. This matches the official tables used by tax authorities including the ATO for distillery compliance.
Direct Reading ModeContainer Weighing Mode
Container Weighing Mode: For measuring spirits in barrels or large containers. Enter the total weight and container weight to calculate the net spirit weight.

Dilution Calculator: Calculate how much water to add to reach your target ABV. Perfect for diluting cask-strength spirits to bottling strength.
Volume of spirit before dilution
Blending Calculator: Mix two spirits of different strengths to achieve a target ABV. Useful for batching and blending operations.
Fortification Calculator: Calculate how much high-strength spirit to add to increase ABV. Common for fortified wines and liqueurs.
Obscuration Calculator: Correct ABV readings for spirits containing sugar. Sugar increases density, causing hydrometers to read higher than the true ABV.
