As I mentioned in another section, I finished up a Dogfish IPA clone using White Labs California V Ale yeast. I would like to salvage some of the yeast for another IPA I will be making in a few months. My question is can I save some of the trub from the primary fermenter? I have never propagated my own yeast or even contemplated it. I would love to since it costs so damn much for fresh, liquid yeast. Does anybody have a simple, good method for saving yeast from a batch? I work in a biochemistry lab, so I have access to a lot of simple, sterile items (tubes, growth media, etc.) that might be harder for others to get. Any and all info on yeast saving would be great.
