I would like to draw attention to a recent ratebeer.com post which obviously involved a problematic beer.
http://www.ratebeer.com/beer/hallertau-porter-noir/89435/30436/
I this case it appears the crownseal has failed and the beer has lost carbonation and become oxidized.
According to the Ratebeer Craftbeer Introduction:
“What to do with spoiled beer? As a rule, dump it. Don’t rate it. It would be considered Rateable only if you had it at the brewery (where the brewer should be held 100% responsible for quality control), in the presence of the brewer outside of the brewery, or if you’ve had the beer several times and found it to be infected on numerous occasions, indicating a chronic problem. If a group shares an infected bottle, only one rating should be entered. No need to slander a good beer’s name simply because of one bottle that just happened to be split amongst multiple Ratebeerians. That is not good form.
If the beer is a vintage beer, caveat emptor applies. No matter how many good ones you try, vintage beers should always be considered a crapshoot. If the beer is not a vintage beer, or comes on draught, send it back. Don’t pay good money for bad beer.
Lastly, if you are unsure if the beer you’re holding is spoiled or not, check out the other ratings. Do they talk about the same characteristics you’re finding? If not, it probably is infected. But if most people seem to agree that the beer does in fact taste medicinal and a little sour, it may just be that the brewer intended it that way. “
Rather than make mindless and frankly, somewhat offensive speculation as to the production methods, possibly a better plan is to inform the brewer privately of the issue with as much information as possible. The likely result being a “thank you” and a replacement bottle or 2 sent back.
Lets all try to act positively to improve the quality and image of the local beer scene.
