so I just purchased my first keg (5 gal. sanke type) and am I little confused with all the carbonation information, particularly the time it takes the co2 to distribute itself throughout the beer before you're ready to roll. The reason I"m confused is, I work at a bar (which is where I want to hook my beer up for our staff Christmas party) and as soon as we tap a keg we serve it right away, so I'm wondering why I wouldn't be able to do the same with my beer.
