I had about 2.5 gallons of extra wort after brewing so I decided, after my buddy suggested, to try a wild yeast experiment. I ran off the remainder of the wort into my extra brew kettle and let it sit outside uncovered for about 18 hours. Too bad it was already cooled. Earlier today I racked it into a carboy and put an airlock on it.
Now I'm not sure what to do next. I'm hoping to grow wild yeast not so much the bugs so that why I'm locking it up with the airlock instead of a stopper and wooden dowel.
I plan on leaving it for a few months to see what happens and will report as I go along. Has anyone ever tried this? What was your result, any good, any bad?
Here's a shot of the wort from earlier today. To bad you can't see the gnats floating in it..
The og was 1.064. I plan on testing the gravity in 1 month and will keep everyone updated.
