Yes crazy, but it works - (as long as everything is sterile clean.) As Homer says, mmmmm....beer.
You gotta keep it simple. If you are lying awake at night worrying about the specific gravity of a malty sludge in a keg - you got problems. (Keep the bottles in a plastic, box - in order to clean up any mess that may occur. Only happened twice). The rest were manna from heaven, syrup of the gods yada yada. You can also get wine bottle coolers (wetsuit material) which fit perfectly over a bottle of beer or use a vacuum thermos mug ( they hold about 450mls ( 3/4 a bottle)
See how Aussies and yanks can speak the same language, eg - beer o'clock is when??
