I had one WLP001 vial of yeast that was only 14 days past its "best buy" date. I made a starter on a stir plate 2 full days before brewing. I got good growth as estimated by an increase in creamy opaqueness of the start wort post 2 days (looks like most starters I make, so no worries there).
Then I crash cooled it overnight, anticipating I'll pitch the slurry only the next day into a Brown Ale.
I never got to brew the brown ale sad to say.
So now I have yeast still in the fridge and settled out. The spent starter wort still above it.
Which route is the best course of action?
- Pitch the slurry as is after bringing it to room temp.
- Decant spent wort and add new start wort day of brew session.
- Ditch the whole thing and start fresh.
- Something I didn't think of.
EDIT: Tonight I am going to make a gallon of starter wort and awaken the yeast on the stir plate in there. Then I am going to use it for brewing tomorrow night. I'll update on the final beer later if I remember.
