You've probably already seen this if you've had an issue, but it appears Goose Island had a couple of their 2015 Bourbon County variants, coffee stout and barleywine, that "drifted outside their target character" and "developed flavors not consistent with our expectations". It doesn't appear that the entire batches of those variants are infected but they are offering refunds on all coffee and barleywine bottles purchased.

I never saw a coffee variant on the shelf here, thanks Chicago, but I have a couple barleywines in the closet. I've read there's no time limit on the refund, so if they do turn out off, I might give them a call.
