So I made a starter of wlp090(using yeastcalc) and it should be already to go for tonight. Question is; I have 3 additional vials of wlp090 that are over a year old, I'm guessing they are probably about 10% tops at this point. Should I just toss them in when I pitch or am I risking some kind of off flavor from dead yeast or something? Not concerned with overpitching.
