Default off flavor in my IPA

so i kegged my american IPA on 9-16-09

this was brewed on 7-6-09


once caarbed i chilled it and tried it. it tasted great. now(11/7) its been in the fridge for almost a month it has this off flavor. one of my friends described it as nail polish.

is this an infection?
she said something about wild yeast. is this something i should cellar and let it age for a while? or just dump it?

Any further description of the off-taste? I know what nail polish remover smells like, but can't really place nail polish.

Thats pretty weird that it started tasting like that after being kegged for a while. Solvent flavors are usually indicative of fusel alcohols caused by hot fermentation temperatures. I would think you would have tasted those right away though. It could just be that your hop flavor and aroma are starting to fade, which are exposing the fueel alcohol flavors since the beer is 4 months old.

That's probably fusel alcohol. Usually caused by hot fermentation.

I'm surprised it tasted good at first and then later developed that flavor. Maybe it's something else.

[Edit: Ed's fast on the draw. ]

Post the recipe and such. 90% of what I brew and drink is some sort of an IPA. I'm not an expert brewer of such, but I'm more than familiar with tasting them. :P

It isn't over carbed is it? Maybe it has a carbonic acid taste that you are picking up. Although people usually describe that as more metallic I believe.
