A while back I moved into a new apartment. I intentionally packed all of my beer brewing stuff last, so nothing would be lost in boxes. Anyway, I forgot that I had a vial of liquid yeast (London Ale) in the trunk. It has been consistently below freezing here for over a month.
A few days ago I made a starter out of this yeast that has been frozen solid for a few weeks. It took about 2 days before there was any activity. But it is now bubbling away (for a day and a half now).
My concern is that it never formed a Krausen. It got very cloudy, and you could see visible CO2 bubble going to the surface, but no foam at the top. Does anyone think that it is possible that there were a few Lager yeast cells mixed in, and they were able to survive the freeze? Only the strongest survive, and they were subjected to some pretty harsh conditions (Down to -20F at one point).
