Funny Aftertaste In Korona Clone

[jamiefbacon]

Hi all
about 6 weeks ago i bought a Korona FWK off CB, I used a Wyeast 2007 Pilsen Lager yeast, when i smacked it i left it for two days and it didnt fire up so i opened and put into a litre starter which eventually started up so pitched. Fermentation when good and finished were it should have, fermented for two weeks, so then kegged and have had it at 2 degrees for about 3 weeks now lagering. My problem is that the beer tastes okay but has a foul after taste im thinken it may be infected but not sure?? the taste is hard to describe its a bit like the tang you get from a cheap kit beer fermented at to high a temp

any help would be good thinken im gunna have to chuck it.

cheers jbacon

Here ya go.
Should help you decide whether it's time to wait or free up the keg.

Ooooh nasty not what you want from a FWK considering the price of them.

Not sure how far you are from CB might be worth bottling a sample and let Ross have a taste and get some feedback.
