Washing and Freezing Yeast with Glycerin in a Frost-Free Freezer

In this post I'm detailing a method I have used to wash and freeze yeast from a slurry, including how I made my glycerin mixture. I did this ONCE at the time I wrote this post, so I am new to this stuff. Yes, this has been done before by others, and I provide links to a few sites where I got my info. This post is meant to track the method I am using.

A big ol' healthy starter. This is what
we're after! 

First off - a warning... This is a new process for me, and I'm still learning all the "best practices." I culled my method from a few sources--most notably a friend on the Albany Brew Crafters homebrew forums who has been banking yeast for awhile now, the washing and freezing yeast page on swedhelm.net, and this great how-to write up on Homebrewtalk. Seriously, check out these resources -- they go into more of the "why" behind this process. Also, I'm doing this for temporary storage purposes of some of the strains that , and don't have a giant lab or complex equipment (beyond that of a geeky brewer). I work under sanitary conditions, not sterile conditions. Some will scoff at this, but I'm going for simplicity here, and don't want to dedicate too much time or money to this endeavor. I use star-san because that's what I have. I don't own a pressure cooker or a microwave (its ok to laugh...), so I use my stovetop and electric teakettle.  I am not a scientist, nor do I play one on the internet!!
