Will Yeast Capture and Step Up

[Arminius757]

So I decided to give this whole wild yeast capturing thing a try. I went back into the woods and found some wild raspberries that I plucked and put into some wort and let sit for a week. I got a nice layer of some creamy looking stuff that looked very much like yeast. So I decided to stick it in the fridge, let it settle out, and decant the liquid and pitch to a small starter. I have had the starter sitting on a stir plate for the past 3 days now, and there has constantly been an inch thick white foam on top, almost creamy white like the head of a nitro beer. There has been a touch of what looks like krausen on the side of the flask, but otherwise, it still seems like this thing is bubbling away 3 days later. Do you guys think I actually have something here? Or could it be something else? Should I keep it running till the foam falls? Or should I cut it off now and stick it in the fridge to see what drops out of the solution? It smells pretty good right now, I got a nice berry sweetness with a touch of barnyard funk at the end. Any help would be appreciated!

Give it a taste! Pediococcus and other lactic acid producing bacterias can bubble and give off a yeasty appearance. If it tastes sour, it may be predominantly bacterial or just a more sour wild yeast! Whatever it is, be ready to inoculate all your plastic brewing equipment and tubing with a bacteria that may be present in future batches to come! I hate to repeat what everyone says and already knows, but it's something to consider!
