Can someone point me to a link or video that would show me how to reliably harvest yeast from trub? I've not ever done it before. Going to try and harvest US-05. I know it's inexpensive but I'd like to learn what all the fuss is about. Can I put it in the freezer, how much to I get, how to store for how long etc.. that sort of stuff.. google just overwhelms with all kinds of stuff that I get skeptical about.. I figure you guys would be more reliable at pointing me somewhere than brewmaster google would be.. thanks in advance boys..
