I see that there have been some threads about this topic in the past, but I've yet to find a diagnosis and some agreed upon suggestions. Here is the situation:
I brewed a Scotch Ale a few weeks ago. After an appropriate time in the primary, I racked to a (well-sanitized) carboy two days ago for clarifying (the stuff was still very murky). I used some neutral Knox as a fining agent (you know the drill). I just noticed some small patches of bubbles forming on top of the wort. I removed the airlock to get a whiff and...UGH. Extremely sour, vinegar like smell. Please know that this this beer smelled great while in the primary.
I suspect I'll need to dump this batch. Any ideas as what went wrong? Very discouraging.
