How long does beer last when put into a keg? How do you guys go through this much beer?! lol
I'll let you know when one goes bad from sitting around. If you do a good job keeping bugs and Oxygen out and you keep it cold it should pretty much last forever. Some styles don't age well so those my become less desirable, on the other hand some styles do age well and only get better with time. The fact that it's in a keg shouldn't affect how a beer ages though. Mist of mine are sadly empty within 3-6 weeks, I do have a Scotch that has been chilling for 6 months that I brewed for Christmas.
