Also, I went over to my FIL's last night to keg some hefeweizen and we needed room in the cooler. So I grabbed a keg of stout that had about 1.5 gallons left in it that was a year old and told my FIL to dump it, it's probably OK, but we need the room. Instead he got a pitcher and filled it up. After we were done with the hefe we sat and talked about shit and watched the hockey game while we killed the gallon and a half of stout.
It was still a good beer!
