My latest brewing blunder occurred last week Sunday.
After brewing my latest IPA, I pitched half of a saved slurry of US-05; fermentation was solid within 12-24 hours, so no worries there.
My blunder occurred when I didn't realize that with the small volume of water remaining in the unpitched slurry, that the yeast could freeze. And it did.
Went down to the lager fridge yesterday morning (where i normally keep my yeast sliurries), and the damn slurry was frozen solid, probably for a good 2-3 days since brewday.
I thawed the contents of the flask and made a starter wort today; thawed slurry and starter wort are currently cohabitating on my stirplate.
So PHBT: are my efforts in vain, and the yeast is beyond hope, or is there a decent chance my yeast is going to come back?
