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!
