I've been using a Blichman Beer Gun for a little over a year now and a thought hit me this weekend while bottling up around 8 cases from kegs. Why is it a good idea to purge the bottles with CO2 before filling? You hit the bottle with 1 - 2 secs of CO2 to force out the air, fill with beer until clear beer runs over the top, remove gun (drawing in air) and cap. Seems that all that CO2 you were purging with gets lost as you COMPLETELY fill the bottle with liquid. Am I missing something or have I been wasting a lot of CO2 for nothing?
