Really old, bad homebrew left for months in a cornie - problem?
Will leaving really old, very bad tasting homebrew (no infection issues, just fermented WAY too hot) ruin the cornie keg itself at all or is it something that a good cleaning and a couple of gasket replacements could easily fix?
Cornies are stainless steel. Nothing in beer can hurt them. I just finished my 2003 barleywine. It was in the keg for over six years and the keg is fine. I plan on replacing the o-rings, just because of age.
Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"
