Ok I have had a couple of Wyeast 2565 packs in the fridge for a couple of months. I decided to use them up. Busted the packs yesterday and not much expansion. Looked at them this afternoon and they where finally expanded fully. Made a starter and tossed them in on a stir plate. Question is, are these going to be any good or is alll that dead yeast going to screw it up. Wanted to brew tomorrow but looks like I will have to wait till Tues. in light of this yeast if it is good. Should I just go get a couple of more?
