Homebrew ABV FAQ

Quick answers to common mead, cider, wine and beer ABV questions.

How do I calculate ABV from OG and FG?

Use the standard formula: (OG − FG) × 131.25. Home Brew Calc does this automatically in the OG/FG section.

How accurate is ingredient-based ABV estimation?

It is a practical estimate based on sugar content and target volume. Real ABV can vary due to yeast health, fermentation temperature, and attenuation.

Why does yeast tolerance matter?

If the estimated ABV exceeds the yeast’s alcohol tolerance, fermentation can stall early, leaving residual sugar and a lower final ABV than theoretical.

Can I use this for mead, cider, wine and beer?

Yes. The calculator supports honey, fruits, juices, sugars and malt ingredients, plus OG/FG ABV calculations.
