Found three old Wyeast packets that had manufactured dates of 18, 14 and 11 months ago. Decided to try making 1 liter yeast starters from each of them in order to see if there was much viability in the remaining yeast. Anyone ever try to revive yeast this old with much success? Any tips or advice you have to share for this effort? I am possibly wasting time and DME? Each starter is on its own stir plate.
Thanks,
