As an attempt to get more bang for my buck, i collected an extra 3gal runnings from a dopplebock a few weeks back. I just transferred to a keg to carb, and long story short, I'm thinking I might have ended up with a giant "starter", as this isn't a very tasty experiement at this point.
My question is, though, based on the following information, is it worth going through the trouble in washing the yeast cake (WY2206 - Bavarian Lager) to store up some viable & healthy mason jar samples? The batch went from 1.022 down to 1.009 at 55F in one month. Is such a low, atypical SG not condusive to healthy yeast growth for future use?
Thanks in advance.
