Co2 vs. N2 vs. Distance?
At my bar I am presently running 12 draft lines all on a C02/N2 gas blend . The total distance from kegs to draft faucets is no more than 30 feet. Do I need to run them all on a gas blend or can I save some money by only running the gas blend on those N2 specific beers(Guinness, etc.)? Straight Co2 is obviously cheaper but I'm trying to understand if I truely need the Co2/N2 mix to push the beer over the 30ft line span. At what distance point do the length of my lines begin requiring the Co2/N2 mix to push the beer properly?
