So my order shipped on Wednesday and wont be delivered until Tuesday .
It is shipping by UPS .
So my question is what temp does a White Labs yeast actually freeze at ?
I did some searching and found that it will only kill off about 10% of the yeast in a freeze assuming it only freezes once in transport .

Ooh yea it is from 0f to 13f here

I placed an order on 12/23 and didn't get delivered until 1/2 because of the holidays. Its been about 15*F here. I let the yeast get to room temperature then activated it and it seemed fine since the packet swelled up. I woke up the next morning and it was going to town in the primary.
