Take a deep breath and hold it. That was mostly nitrogen. Pretty
harmless although not only prevalent but preponderant in the
atmosphere. It's often used as a displacement for air where the
presence of oxygen is undesirable. I don't know why the brewers use it
but their supplier should be able to say what the ratio is.
And you just reminded me, I haven't had a beer in weeks. Gotta go!
Brewers use nitrogen because it is a smaller moicule than co2. Therfore it
gives a much smother carbonation than co2. Most beers you buy are co2
carbonated...and example of nitrogen is guiness from a can or from a tap....
They sometimes mix them to get the desired effect...usually there are
separeate tanks with a mixing thingy that the brewer can adjust...never seen
