What is the correct formula for calculating abv?
I have used the following for a long time for beer:
ABV = (og fg) * 131.25
However, I recently heard it is only accurate in the 5 to 6% range, and for higher alcohol, the following is more accurate:
ABV =(76.08 * (og-fg) / (1.775-og)) * (fg / 0.794)
Which is considered correct for wine?
There is significant difference at higher alcohol levels. Assuming an OG of 1.090 and an FG of 1.000:
ABV = (og fg) * 131.25 =11.8%
ABV =(76.08 * (og-fg) / (1.775-og)) * (fg / 0.794) =12.6%
