So I have this half full corny keg of 9 1/2% amber ale I made October 2008 it has sat in the fridige hooked up to a Co2/Nitrogen mix tank since then. OK I forgot about it I know beer foul. But anyway I was going to dump it out and go get my keg filled at a local brewery for 4th of July. But just for the fun of it I pored a glass and it looks, smells, and tastes fine. It actualy tastes realy good. But I am not sure its good been sitting there almost 2 years. I was going to open the keg and look inside to make sure nothing is growing but I dont want to introduce O2 into it. I don't want anyone geting sick espacialy me.
