Accidentally froze 2.5 gal beer in the fermenter!

So I put an overly cloudy, but definitely finished fermenting beer out in the garage last night, thinking maybe a good cold-crash would help with the cloudiness.
But then I got distracted, and it spent the night in a very cold garage -- it was frozen solid this morning! Did I ruin this batch?

Nope. Bring it in and let it melt and you’ll be fine. Or let it melt halfway, save the liquid (throw out the ice) and you’ve made an eiswhatever.

The freezing itself probably didn't hurt much. I once had a czech pilsner freeze in the keg when a controller wet the bed. It was fine when it thawed. And my memory is a little fuzzy, but I think this beer took a BOS in a fairly large homebrew comp.

Since your beer was in a fermenter, with (I assume) a standard airlock, the only thing I'd be a bit concerned about is the O2 that would have been sucked in as the beer contracted and the headspace cooled.
