So I've used this brand of yeast a few times, without any issues. One time, I forgot to order yeast with my extract kit and had to borrow a packet from a friend who had stored it with his other brewing hardware for nearly a year--worked like a champ. Anyway, I was sitting here bored and decided to read the packet to find out the ideal target fermenting temperature when I realized the package says to refrigerate. *blink* Seriously? We're supposed to refrigerate dry packets of yeast? Anyone?
