I have a BIPA thats O.G. was 1.073 that was suppose to drop to a F.G. of 1.012 according to the recipe the brewing software calculated this would be an 8.0% abv. beer. I hit my O.G. of 1.073 spot on but after three weeks in fermentor and one week in secondary for dry hopping the F.G. at bottling was only 1.023 which is calculated to be a 6.2% abv. beer. It has been carbonating in bottles in the closet for over 6 weeks now. I just tried it for the first time and the taste is not the best beer I have ever made but it is good enough. I have drunk 1/2 the beer over the course of 30 min when I noticed I was a bit tipsy, too tipsy to have drunk 1/2 of a 6.2%abv beer. Which leads me to ponder could the S.G. of the beer continued to drop after bottling getting this beer closer to the 8 %abv. range?
