Well ordered some yeast i was gonna add a ice pack but times are rough and I decided to take a chance without one, bad mistake , the pack took a week yo get here and was warm on arrival, if i had to guess only a small amount of the culture is alive if at all, and its an imperial stout i was gonna brew too , if you were me would you buy a new pack or do you think it can be stepped up and revitalized? Was gonna start with a low gravity 1030 1 liter, then to a 1035 2 liter then proceed as if it was a fresh pack, what would you do in my shoes? Cheers
