Actually, you can fill it right up without worries. The lid is ported to allow gas to escape. There is no reason to go drilling holes and installing airlocks, as the CO2 is just going to escape anyway.
If you have a hard time believing this, try this out: fill your empty Mr Beer keg with water, then shake the heck out of it. Now go change your shirt, because water leaked out of the ported lid.
The Mr Beer keg is especially useful for Apfelwine, because it doesn't really have krausen like most beers do. Just a thin layer of bubbles.
Oh I know the Mr. Beer cap is vented. I was asking what I should do to convert a one gallon wine jug I have into a small fermenter. I figured I couldn't just screw the original jug cap on so I was inquiring as to what to do. That's where the stopper and airlock came into the discussion. I used my Mr. Beer to make my apfelwein and I agree it is useful. Thanks for contributing though.
