How it’s calculated

Base ABV

(∑ abv × vol) ÷ total vol

Weighted average across all ingredients.

Water to add

total vol × dilution %

Added as percentage of pre-dilution volume.

Final ABV

alc ml ÷ (total vol + water)

Same alcohol, larger total volume.

Freeze point

−(0.0082 × ABV² + 0.26 × ABV)

Ethanol-water mixture approximation. Accurate to ±1°C.

Safe storage

freeze point + 2°C buffer

Set your freezer warmer than this. Check for viscosity as the sign you’re too cold.
