do you mean the 'raging *****'? i swear i must have gotten a bad 6 pack of that stuff a month or so ago.
it actually tasted just like this- "Band-Aid" like flavor or aroma, that can also present itself as medicine-like or clovey." it tasted like straight plastic. http://www.homebrewzone.com/phenols.htm
i also got a sixer of FD classic pale ale 2 weeks ago, and it was definitely bad. maybe someone can answer this, but my dad has made 'homebrew' for about 20 years, and, no matter what kind of beer he's trying to make, it always comes out like this- "Chlorophenols resemble the aforementioned taste descriptors combined with bleach. Phenols are usually part of the flavor profile in Belgians and Wheat beers however.", which is a continuation of the paragraph from the above link.
it has sort of a rotten, moldy taste to it. but, my dad doesnt seem to notice it at all. he thinks its fine, and i dont have the heart to tell him it tastes funny. so, any of you homebrewers, feel free to fill me in on why his beer tastes wierd.
i've only gotten store bought beer one other time that had that moldy taste to it, and coincidentally, it was another frederick brewery- 'blue ridge'. i think they arent in business anymore.
