pub gas c02

Blue Pipe:
Air from the air compressor. Used to drive the gas pumps.

Grey Pipe:
Co2 Gas – used these days primarily for lager and Ciders, and maybe a few bitters. Some breweries insist Co2 is used so as not to change the taste of their beers. And a electric or gas pump is then used to pump the beer to the tap.

Green Pipe:
Mixed Gas 30/70 – used for dispensing Guinness, Mild and Smooth-flow bitters. Nitrogen is now added in the brewing process to make the Smooth-flow bitters creamier.

Purple Pipe:
Mixed Gas 50/50 – used for dispensing Lager and Ciders, however you will find white pipe more commonly used.

White Pipe:
Mixed Gas 60/40 – used for dispensing Lager and Ciders

Mixed gas is a blend of Co2 and Nitrogen, in beer dispense Co2 holds the gas in suspension by being at a slightly higher pressure than the top pressure in the container while Nitrogen unlike Co2 does not get absorbed into the beer, so is used to push it up the line to the tap.
