Nitor Gas for stouts

Dave Savoie · August 27, 2011, 10:42:51 AM

Does anyone know where one would get a tank filled 75% Nitro and 25% CO2 ?

Air Liquid can fill it for you...I believe it's called Aligal gas. 75% nitro 25% CO2.

A buddy of mine uses it for all of his ales and prefers it. finer bubbles and thicker head.

Im thinking when i build my 2 Tap mini fridge kegerator to install a stout tap as I plan to have stout on tap at all times

the extra cost would be about $200 for Tank Regulator and Tap

I think its called "beer gas"

Many good quality establishmens use beer gas for all of their beers on tap. It's a bit more expensive than co2 but apparently worth it.

It as simple as just getting Air Liquide to fill my tank with this stuff instead of CO2 next time?

Was under the impression that they won't give you liquid N2, so surely this would require tanks able to withstand higher pressure?

you cant force carb with beer gas well yyou can butr it would take a long long time you need seperate regulator also and tank

hmm... ok. probably won't be running with this any time soon

new tank and reg about $160 ($75-$95 for stout tap)

Yeah I'm planning to rest on my laurels re: homebrew equipment, for a while. I figure I've spent about a grand this year between ingredients and new toys

Add that to the grand I've spent on paintball gear and yeah... SWMBO is likely to start getting angsty :evil:

Comparing liquid nitrogen to nitrogen is like comparing apples and hyenas ...nowhere near the same thing. seems like that beergas is kinda like plain ol' air with CO2 substituted for O2 ...(air=80% nitrogen). Incidentally, unless my memory is REALLY off the mark today, liquid nitrogen is not under pressure

Dave Savoie · August 29, 2011, 12:57:57 PM

75% nitrogen 25% CO2
reason being the nitrogen allows you to push your beer at 38PSI without over carbing it
and the CO2 in it allows you to maintain proper carbonation

Dean · August 29, 2011, 01:00:16 PM

yep ...pretty much air without the oxygen

Richard · August 29, 2011, 01:10:51 PM

Ok here's my reference point - Paintball.

In paintball we have two tanks - CO2 tanks and N2 tanks. The former contains a liquid, and the latter contains a gas (either pure N2 or plain old compressed air). Because of the behaviour of both at around room temperature, the CO2 tanks are built to withstand far less pressure than the N2 tanks (about 1000PSI versus 4.5k PSI), because the N2 is just a gas under pressure, whereas the CO2 is a mix of liquid and gas under (less) pressure. The point is to be able to deliver the same volume of gas for each kind of tank - as you might expect from say an Air Liquide fill.

Therefore if the Nitor gas stuff isn't liquid, then either the tanks are going to be much stronger (to deliver the same quantity of gas as a CO2 canister of comparable size), or the CO2 tanks were built to withstand much higher internal pressures than they really require.
