Alcohol Dilution Calculator
Calculate the perfect dilution ratio for spirits, tinctures, and homemade alcohol solutions
Calculate Alcohol Dilution
Volume of high-proof alcohol you have
Alcohol by volume (ABV) of strong spirit
Use 0% for water, or percentage of weaker spirit
Desired final alcohol concentration
Account for volume reduction when mixing alcohol and water
Common Dilution Examples
Add 300ml water to 1L isopropyl
Add 1.4L water to 1L ethanol
Add 1.67L water to 1L spirit
Add 714ml water to 1L liquor
Step-by-Step Example
Making 40% Vodka from 95% Ethanol
Starting material: 1L of 95% ethanol
Diluent: Water (0% alcohol)
Target: 40% alcohol
Cross Method
Parts strong = 40 - 0 = 40
Parts water = 95 - 40 = 55
Ratio = 40:55
Water needed: (55 × 1000ml) ÷ 40 = 1375ml
Final volume: 2375ml at 40%
Safety Guidelines
Always Add Water to Alcohol
Never add alcohol to water to prevent heat buildup
Use Room Temperature Liquids
Cold mixing reduces heat generation
Legal Considerations
Check local laws regarding alcohol production
Sweetness Levels
Volume tip: 100g sugar = 60ml volume, 100g honey = 75ml volume
Understanding Alcohol Dilution
What is Alcohol Dilution?
Alcohol dilution is the process of reducing the alcohol content of a spirit by adding water or a weaker alcoholic solution. This is commonly used in making tinctures, custom spirits, and adjusting alcohol strength for different purposes.
The Cross Method
The cross method is a simple mathematical approach to calculate dilution ratios. It works by determining the parts of strong and weak alcohol needed to achieve your target concentration.
Common Applications
- •Making herbal tinctures and extracts
- •Diluting medical or isopropyl alcohol
- •Creating custom spirit blends
- •Adjusting homemade liquor strength
Alcohol Contraction
When alcohol and water mix, the total volume decreases due to molecular arrangement. Alcohol molecules can fit between water molecules, causing volume contraction.

Safety Tips
Always add water to alcohol - never alcohol to water to prevent dangerous heat buildup
Use appropriate measuring tools - precision is important for consistent results
