Want to get the exact alcohol concentration in your drink?Alcohol Dilution CalculatorfromWebP.plis a precise tool that will calculate in a few seconds how much water you need to add to spirit or vodka to obtain the desired alcohol percentage. Perfect for tincture makers, bartenders and home-made alcohol enthusiasts.
How does the alcohol dilution calculator work?
The tool is based on a simple but effective mathematical formula. Simply enter:
- the volume of alcohol (in milliliters or liters),
- its current percentage,
- and the desired final concentration.
The calculator will automatically calculate the amount of water you need to add to get the exact percentage of alcohol you need - without experimenting or wasting.
Alcohol dilution formula
The basic formula on which the calculator is based:
V₁ × C₁ = V₂ × C₂where:
- V₁– volume of alcohol before dilution,
- C₁– percentage concentration of original alcohol,
- V₂– volume of alcohol after dilution,
- C₂– expected final concentration.
To calculate the amount of water, just:
Vw = V₁ × (C₁ / C₂ - 1)Why use the alcohol dilution calculator?
- You get the perfect strength of the drink - without guessing.
- You save time and ingredients by avoiding mistakes in proportions.
- You can create tinctures, liqueurs and vodkas with precisely selected concentrations.
- The tool works for all types of alcohol - spirit, rum, whiskey, vodka and even ethanol perfume.
- Works online, no installation required, and also works on smartphone.
How to use the calculator?
- Enter the amount of alcohol you have (e.g. 500 ml).
- Enter its current concentration (e.g. 96%).
- Enter the expected final concentration (e.g. 40%).
- Click "Calculate" - the tool will provide the amount of water to add and the final volume of the drink.
Most common use cases
Creating tinctures
Dilute spirit 95% to 70% or 40% - ideal for preparing fruit and herbal tinctures.
Homemade vodka production
Get the classic 40-45% alcohol content - without the risk of a drink that is too strong or too weak.
Preparation of liqueurs
Calculate the amount of water and sugar syrup to maintain the appropriate alcohol concentration in the liqueur.
Chemical applications
The calculator will also be useful in laboratories and cosmetics, e.g. when preparing ethanol solutions.
Practical tips
- Usespring wateror boiled water - you will avoid the drink becoming cloudy.
- Dilute slowly and mix thoroughly to avoid local differences in concentration.
- After diluting, set aside the alcohol for 24-48 hours - the flavors will stabilize.
Spirit dilution calculator – how to dilute 96% spirit to 40%?
The most common case for which the spirit dilution calculator is used is to reduce 96% rectified spirit to the strength of vodka, i.e. 40%. The theoretical formula is simple: amount of water = V · (initial power / target power − 1). For 1 letters of 96% spirit: 1 · (96/40 − 1) = 1.4 letters
