So like much of the rest of the US it's been relatively cold here in the NYC area the last couple of days. Last night at 7:30 pm I stuck a bottle of '12 bcbs (15%) and a bottle of St. Arnold Endeavor (8.9%) outside. The temperature last night got down to 10F, and through most of the day was between 15-20F. I took the bottles in tonight and opened them up (after 24 hours outside at temps ranging from 10F - to about 20F). Absolutely zero freezing. The BCBS was totally unaffected as far as I could tell. the DIPA seemed a bit less carbonated until it warmed up. After it was warmer, I don't think I would've been able to tell the difference. Tomorrow I'm going to make it a bit more precise and try it with varied ABVs and different styles, depending on what I can find at the local beer store (two 5%, 6%, 7% and 8% beers, one to freeze and one not to freeze, then taste the two after the cold one has warmed up). Obviously nothing close to scientific and I wouldn't do this with a geuze but I thought it was interesting that there was no freezing at all and that the beer didn't seem to be affected.
