My question is, what exactly is most likely to have happened? I thought that once fermented the acidic / alcoholic nature of the brew made it impossible to be "infected" by wild yeast and Bacteria.
What does that mean "forgot to close this one" and "spent a month on the fridge" Do you mean you left an open bottle sitting on top of your fridge?
and "tasted . . . fowl"? Like chicken? JK on this last comment
No it is not at all impossible to infect a fermented beer. There are plenty of types of spores and wild yeasts and bacteria that can turn an unprotected beer foul. Besides, the alcohol will evaporate out of an opened beer.
