One of my first oatmeal stouts was one of my favorites. Toward the end, I was in a hoarding mode. I quit offering it to others. I bottled the last of it and put it in the back of the freezer. It is indeed sad when it is done. But like has been mentioned, it opens space for the new keg and a new creation!
Denny, you need to step up and get a temp controlled fermenter. That's to long to go without a lager (Pils in my case).
