Dear Michael, By all accounts, if your kegerator's lines are clean and the kegerator is working properly, you can keep a keg of beer staying fresh for up to 6 months. 4 months is more likely. If you have to leave your home bar for a while, it is recommended to disconnect your beer and gas lines while you are gone.
The Kefir I buy has a refrigerated lifespan of about two months. I'm guessing this is homemade kefir -- in that case, you'll just have to experiment. There will be an obvious change in its taste when it is starting to go bad. In my experience, it becomes overwhelmingly bitter/sour.
