What’s the longest amount of time anyone here has gone with freezing and had acceptable results?

I’ve gone years with excellent results.  But mine are at -80C.

Crap. My fridge only goes down to -70.

If you can really get them that cold then they will be fine for many years in a 20% glycerol solution.

I think he was being sarcastic… -70 to -80 the yeast will be shivering so still that they won’t notice the 10 degree difference. 

Great stuff! I’m going to try this glycerol mix.
