Default What is this?

I opened my primary to take a gravity reading on my American wheat and this is what I found. Any idea what this is?

I've done 6-7 batches and I've never seen this before. This was brewed on August 12 and is pretty much at it final gravity.

That would be an infection. Most definitely.

I'm guessing it's the work of bacteria, maybe lactobacillus but I really don't know. Let it go and if it grows filmy bubbles then lacto is what it is. That will make it sour.

If it grows fluffy hairy balls all over, it's probably wild yeast, maybe brett. That will make it taste funky, but not sour.

Any way you slice it, it's not gonna be the beer you were hoping for. Me, I'd run out and get some roeselare and some canned tart cherries and sour it up and push it into a cabinet for a year.

Cheers.

What if I transferred to secondary right now from underneath. Would it be decent?

If this is an infection can I rack from underneath to secondary and be ok?

Don't know. Probably not (the effect you see on the top is the reaction to oxygen, but the bacteria is probably found through the beer). If you taste it and it tastes good now, you could get it really cold and that would stop the growth of what you see there.

If you bottle, you probably have a problem.

I racked to a glass carboy so I can keep a better eye on it. Whatever was there clung immediately to the auto siphon. In secondary now it looks like regular wheat beer. We'll see how it looks in the morning.

Sometimes you just gotta let a bad batch go.....

Eh... I'd let it ride. Doesn't look so good, but if you've got the space for it, see how it turns out. Could be the new taste sensation for all we know. Or it could taste like sewer water smells. (had to add that, since I've never tasted sewer water)

Oh... One more thing... Soak your primary in bleach water so it reduces the risk of anything hanging around for your next batch.

Oh yeah Squeeky. As soon as the batch was in secondary the primary got a thorough scrubbing and now has 6.5 gallons of bleachy goodness soaking in it. Hopefully this is my first and last confrontation with whatever this is.
