Hey All,
I had a temp probe fall out of the fridge during the week and partially freeze two fermenters that were crash chilling. I estimate the egdes got to about -3 and for possibly up to 18 hours. There were ice crystals in the beer but it wasn't frozen solid.
As the batch was to be largely bottle conditioned, I decided to pitch 1/2 a packet of US05 in the bulk prime, informed by a few threads, some from AHB.
I did some test bottles without the bulk yeast.
After just a few days, all bottles, even the frozen yeast only, are carbonating fine (PET squish test).
Most people will say pitch more yeast. I'd still consider all factors if this happened to you, and maybe err on the side of caution and cloudiness, but just an alternative view - it may well be just fine without extra yeast.
