Someone much smarter than I am can probably offer better advice. But to my knowledge, as long as it doesn't freeze it's fine. I keep all my harvested yeast in mason jars in the fridge. No problem yet.

I keep mine at 33-35.

even if it freeze you should be fine if you make a starter to test viability. I've had to revive yeast from frozen jam jars a couple times before due to accidently sliding the vegetable>>>meat thing on my fridge drawer
