Thanks but I've already been there. In fact, I've purchased most of my setup from beveragefactory.

Here is a table for CO2 pressure/temperature:

I'm looking to find something similar for Stout gas mix.

PS. This would be a good table for the fellow that posted that he was getting too much foam.

I've had the pressure at 32psi and it seems to pump a near perfect pint as far as I am concerned. I can pump a better pint than at many of the local watering holes which carry Guinness Draught.

I'd visited that site in the past. I just refreshed my memory of it by visiting it again. Many broken links to their product images.

The carbonation chart yu need is at

(its a pdf file, you need acrobat reader)

Guinness draft isnt really all that magical once yu understand how it works. Most fizzy lagers and ales need 10-15 lbs of straight co2 pressure on them at 100% co2 to maintain 2.2 to 2.6 volumes of carbonation and avoid foam (see

).

because of this most draft systems have about 15 lbs of restriction built into them (draft beer restriction is simply the resistance of the line to produce a 1 gal/min flow rate at the "restriction pressure). the delima of guinness is that it only needs about 4 lbs of pressure to maintain 1.2 volumes of co2 in the beer.

A draft system needs 10-15 lbs of pressure to push the beer out the faucet, plus the guinnes faucet has 15 lbs of restriction when that little restrictor-sparkler disc is placed in the nozzle. this results in the need for 25-30 lbs of pressure to dispense guinness, but anything over 4 lbs will change the carbonation of the beer (and the cool flat-creamy taste and fun pouring characteristics).

wa-la look at the mcdantim chart (and read

if ya really want to understand). the partial pressure of the co2 at 25% co2 and 75% n2 is perfect for 38 degree guinness at 30 psi.

That's an interesting presentation. I sent it off to my color laser printer for permanent archive.

Thanks, the physics I know and understand.
