Freezing slurry?

[burtom]

Hi. I’m about to start storing yeast and would like to go simple and just add glycerin to yeast slurry and freeze. How would I go about ensuring the sanitation of the glycerin? Could you just boil it?

Any help would be appreciated.

I have never done anything to the glycerin.
