I made a wild yeast beer once, and it was pretty good. It was the "Really Old Style" ancient Sumerian beer recipe from BYO from like 2008 or something like that. Basically mashed up a few pounds of pitted dates -- I think they were from Turkey -- in a gallon of water, and let it sit for 3 or 4 days. Fermentation begins all on its own pretty fast. Then brew the rest of the beer, and pitch the date wine "yeast starter". No hops were used in this ancient recipe. The wild yeast threw off a lot of sulfur during fermentation, but the final beer had no sign of it and was quite crisp and clean. The final result was also sour, no doubt from a wild Lacto infection. No biggie. Scored in the 40s in competition. I didn't like it all that much, and I probably won't brew it again, but some of my friends who like sour beer loved it. It works.I highly recommend using mashed up fruit for your wild yeast source, rather than leaving a beer out in the open elements where it is almost certain to contract some really nasty molds and who knows what else.

Pretty cool. I personally wouldn't use that guys method either (at least not at that scale). It did give me an idea as to another method to try...so far I'm thinking I'll be doing the following:
  • Boil up some DME (with lemon juice cause nasty bacteria hates acid):
  • leave a small portion of the wort in a few petri dishes overnight in my yard
  • make the wort gelatin, add to petri dishes, leave it out overnight
  • get fruit from farmer's markets (thinking peaches and what-not) and put their skins in the wort (IT PUTS THE LOTION ON IT'S SKIN OR ELSE IT GETS THE HOSE AGAIN!)
After I figure out which method I like best, I'm hoping to send a few petri dishes to brewman and have him collect some yeasties in an awesome florida orange field.----------------On another note. I just purchased a bunch of "lab" equipment from northern brewer - a 2000mL and 500mL flask (and foam plugs...aka bung blugs, or as i like to call em, butt plugs), 20 petri dishes and some DME.Now, before I bought that stuff I did read the reviews on the flasks...it seems a lot of people were complaining their flasks shattered when they tried boiling water in em. Has anyone on here had any experience with NBs flasks? I know they aren't pyrex, but I'm hoping the people that shattered theirs are just morons.

More likely than not you'll get petri dishes full of pesticides. They spray the mortal dogshit out of active citrus groves. If you know anyone around the Orlando where there are acres of abandoned groves, they might be able to help you out.

hence i said orlando-ish...Orlando = Disney World.Disney World = Florida.Brewman lives in FL, therefore Brewman lives near Orlando.I reject your reality and substitute it with my own.
