I harvested yeast from my last batch. I put it in jars and stuck it in the fridge. Well the yeast froze somehow. I took it out and let it thaw some and then put it back in the fridge, this time not pushing the door completely closed, so the yeast got to room temp. Now it is back in the fridge and back to normal temperature.
Is it still usable or should I pitch it and start over?
