So yesterday I started my first attempt at a frozen yeast bank. I was under the impression that by using the glycerin solution the vials never actually freeze solid, but this morning I woke up and that is what has happened.
I mixed up a solution 25% glycerin and 75% water, mixed 5 ml of that and 5 ml of yeast/beer in the vials, then put the vials in isopropyl alcohol and into the freezer.
What did I do wrong?
