Freezing not-100%-dry Kveik yeast

Hi folks. My schedule got all messed up before leaving on vacation a few weeks ago so I ended up having not-100%-dry Kveik yeast on a tray in the oven as we were about to leave. (I’m still cursing myself for not just stashing the slurry in the fridge, but can’t change it now.) I put the mostly-dry flakes in a jar in the freezer and when I came back there were some ice crystals inside. Any thoughts on how this will affect the yeast’s abilities?

I would guess you probably killed some, but kveik is resilient and can handle an underpitch, so it will probably still work. It never hurts to make a starter to find out, though.

Good thinking, thanks!
