About Alcohol Distilling Calculator

The Alcohol Distilling Calculator is a comprehensive utility designed for home distillers and spirit enthusiasts. Distilling is an art that requires precision—whether you are proofing down a high-ABV distillate to bottling strength or blending different batches to create a consistent product. This tool features two primary modes: Dilution Calculator: Determines the exact volume of water needed to reduce a spirit from a high ABV (e.g., 95% neutral spirit) to a target ABV (e.g., 40% vodka). It uses standard concentration formulas to ensure accuracy. Blending Calculator: Solves the complex math of mixing two spirits of different volumes and strengths. It not only calculates the Final ABV and Total Volume but also provides a Cost Estimator to help you price your final blend based on ingredient costs.
