How Do You Calculate ABV?
Subtract final gravity from original gravity, then multiply by 131.25. For example, OG 1.055 and FG 1.012 gives about 5.64% ABV.

Frequently Asked Questions
How do I calculate ABV from original and final gravity?
Calculate ABV by subtracting final gravity from original gravity, then multiplying by 131.25. The alternate formula is also shown for comparison.
What is original gravity (OG) in brewing?
Original gravity is the specific gravity reading before fermentation. It estimates how much fermentable sugar is in the wort, must or cider before yeast converts sugars into alcohol.
What is a typical ABV for homebrewed beer?
Typical ranges vary by style: light lager is often 3-4%, IPA often 5-7.5%, stout often 4-7%, and barleywine often 8-12%.
What is the standard formula for ABV calculation?
The standard homebrew formula is ABV = (OG - FG) x 131.25. Hydrometer temperature correction and recipe style can affect practical accuracy.
