Well did my second batch today...It is an Auburn Amber Ale from AHS... Missed the OG by .006 it was supposed to be 1.048 and I ended up at 1.054-ish. I'm thinking it was due to Boil off.. The temp out today was 22 degrees F.
Alright, thanks for your post and theories....now why are you posting a thread? If you want any serious comments, we'd need to know your recipe and techniques. Other then that, it's your guess as to why the OG is different then intended.
