I have wondered about this for a while, just never got around to asking anybody. Before using the Beersmith software, I used to use the following formula to calculate the alcohol by volume:
(OG - FG)/7.36
Using a recent pils as an example,
OG: 1.046 ; FG: 1.010
Beersmith alcohol (abv) calculation: 4.7%
Using above formula: 4.9%
Which one is correct? I just finished labeling some beers to give some friends and relatives and I put the Beersmith abv's on the label, and figured they should probably know the "real" abv.
Also means an IPA I made a while back, that I thought was 7.1%, is actually more like 7.8% (including a provision for priming sugar). That's getting up there I reckon.
