If I crash my Belgian to 32F for a couple of days can I still use priming sugar or should I use fresh yeast during bottling? I am wondering if that cold of a temp will kill my yeasts. Wyesat1214 and WLP575
Why crash to 32°? Crash to a few degrees higher and you would have no worries with the fermentation yeast. Adding fresh yeast is never bad, though, and almost always a safe bet.
with the alcohol in the beer, it won't freeze at 32*F so it would be OK to crash to that temp. also, it will take a long time for the entire volume of beer to get down that cold. that's quite a bit of mass to cool.
yes, you still need to use priming sugar. no, you don't need to add additional yeast. you can if you want to, but i've never added additional yeast after a multi-day cold-crash and i've never had a problem carb'ing.
