OK, having read a thread about frugal brewing on another forum got me thinking about the yeast vials I have in the freezer that I got from a user who was getting out of the hobby for a bit.

Like many cellular organisms, don’t yeast cells rupture when frozen without the addition of glycerin?

Yes, they do.
