Let me preface by saying I'm a beer idiot. Don't like it, don't drink it. That said, I bought some cases for a party a while back and have since stored the leftovers, still in cases in the back of the pantry.
How long will it go? Want to get rid of some today for July 4 cookouts, but I don't want to gross out my fellow BBQers. Most of the beer is low end: Rolling Rock, Bass, Sierra Nevada, Brooklyn Lager, etc. In 12 oz bottles.
Edit: Just opened one of the Brooklyn Lagers and it seemed ok. Still a bit carbonated. But I'm no judge. Is there something that will tell me if it's irredeemable?
