That's Lactobacillus, not wild yeast. Smell is accurate.

Yeah, you have mostly lacto. It's possible to culture yeast from raw fruit and grains but it's a little trickier than wetting some grain and waiting.

I'm aware of 2 main processes with what you've got:

1) Let it go for 24 hoursish, until it smells like bad yogurt, then boil to stop the process and brew as normal (i.e., don't let it get to rotting corpses)
2) Let it go all the way to rotting corpses, then blend with fresh batch (pre-boil) to the ratio you want.
