Dilution and Fortification Calculator

How It Works

This calculator estimates volume additions for ABV reduction or fortification.

1. Choose dilution or fortification mode.
2. Enter current volume, current ABV, target ABV, and fortifier ABV if applicable.
3. Review required addition volume and resulting final volume/ABV.

FAQ

When is fortification impossible?

If fortifier ABV is at or below target ABV, the target cannot be reached by addition.

What does dilution mode assume?

It assumes added water contributes volume without alcohol content.

Should I add in one step?

Use staged additions and re-check ABV to minimize overshoot.
