I hope this is not a breach of forum rules but I just wanted to bring this to more peoples attention as people trading may not hit the regional forums. http://www.beeradvocate.com/community/threads/ba-muy-bonita-issues.208245/ Lots of people reporting infected bottles (although lots also reporting no problems). Trade at your own risk for this one.
We opened one at a tasting a few weeks ago. Nose was absolutely horrific - like garbage/sewage/wet socks. But it tasted amazing! No idea how this is possible, but as it was passed around, the general rule was "just don't smell it!". No idea how a beer could taste AMAZING but smell like an absolute horror show, but this one nailed it.
