This is unrelated to the question I just posted here. (Yes I'm having a bad day regarding temperatures, both too hot and too cold!)
My yeast had a temperature range of 60-72*F. It has been brewing for 4 days. When I came home from work today I noted it was at 72*F, so I put it in an icebath.
After an unknown amount of time, its temperature dropped to 50*F.
I have put a fermwrap on it and it is slowly working its way back.
What are the consequences of this? Unlike my other question, I'm sure I don't have to throw it out, but I'm worried nonetheless.
