Wyeast Unrefrigerated

[frankinla]

Hey Guys,
I accidentally left my new pack of Wyeast overnight in my car. Do you think it's affected at all? Should I go back and get a new cold one?

You'll be fine. If you're brewing in the next several days, smack it now before rechilling it, or else the yeast might mock your indecisiveness. On the off-chance that it doesn't swell, you can go replace it, but I'd bet money it's fine.

A similar question that's been on my mind for a while (sorry to the OP for a slight hijack)...

Roughly how long could one leave liquid yeast at room temp and still be able to use it successfully?
