There is an alternative! With brew that came out allright, no spoiling etc, just capture the trub! Put it in one of those extra clean beer bottles, cap, and store in your refigerator. You want to do it before adding priming sugar but it's safe to do it after. It's loaded with vitamins and billions of dormant microbes that when pitched will kick your wort into superFreshalist hoPpy aliquencious beer. You could trade them at the homebrewers club for other yeast cultures or send them to a friend for a gift. So you see spanky, not everything cheap is grade crappy.
