I bought CVS brand Pure Glycerin to prepare my yeasties for freezing.... Some people on the forum have said to buy the kind that is safe for ingestion, however, this stuff say's "For external use only."
Is it safe to use this stuff? I'll be freezing 20 mL of yeast solution in test tubes, so I figure 5 mL of glycerin. Is this OK?
I'm putting this stuff into my test tubes and firing up the autoclave... If I hear its no good, I guess I wont be saving any yeast from this starter...
Thanks
