So my first try at culturing wild yeast was less than stellar, to put it lightly. I just did the leave some wort sitting out and see what starts eating it with which I fermented a beer, but it turned out to be an abomination. For my next try I'm going super geek, so I bought some petri dishes, a 100x microscope, some DME and some gelatin. From some instructions I found online I'm going to prepare the wort and add gelatin to make it gel in the petri dish. I'm going to let the petri dishes sit out for a few hours and then cover them to start growing whatever landed on it. The only question I have is, how do I differentiate yeast from other bugs? I don't know if 100x is enough for my microscope to do any good, but it's what I've got. Thanks for any help.
