Calculadora de Diluição de Álcool

The Alcohol Dilution Calculator helps determine the amount of water needed to reduce the alcohol content of a beverage, such as grain alcohol or homemade spirits. The calculation uses the formula C₁V₁ = C₂V₂, where C₁ and V₁ are the initial concentration and volume, and C₂ and V₂ are the desired final concentration and volume. The water to add is the difference between V₂ and V₁.

To use the calculator, enter the initial volume of alcohol (in milliliters or liters), the initial concentration (in % ABV or °GL), and the desired final concentration. The tool automatically calculates the final volume and the amount of water to add. For example, to dilute 1 liter of 96% alcohol to 70%, about 371 ml of water is needed.

This calculator is useful for those making homemade alcoholic beverages like liqueurs, vodkas, or tinctures, and need to adjust alcohol content for consumption or medicinal use. It is also applied in cleaning, where 70% alcohol is more effective than 96% for disinfection. Remember that dilution changes total volume and may affect flavor and stability.

Precautions: always add water to alcohol, never the reverse, to avoid exothermic reactions. Use distilled or filtered water to avoid impurities. The formula assumes additive volumes, but in practice there is slight volume contraction (mixing alcohol and water). For accuracy, measure with calibrated instruments.
