Infection?

[David Koepke]

I put frozen fruit(blackberry, raspberry and blueberry medley) in the fermenter and I assume some wild yeast got in from the fruit. I now have a fruited sour. Definitely a film on the top and to me it does not look like yeast rafts. Let me know your thoughts, please.

Yea that's probably bad. Large waxy bubbles is typically trouble. Normally, I'd say dump (I have a hair trigger for this sort of thing). HOWEVER, with a bunch of fruit in there, maybe you get something magical. I suggest immediately pitching Roeselare in there and attempt to rein in the fermentation. Get two pkgs, don't bother with starter, just dump them in there.

While you're waiting for your roeselare, if possible, reduce the temperature to as close to freezing as possible.
