Is beer gas co2 cut with nitrogen or what is it
yes, apparently it's so you can use more pressure without also over-carbonating the beer (more pressure being useful eg. if the keg is downstairs from the bar)
Never really thought about it, makes sense though.
I've heard of it before but wasn't sure I remembered correctly, where I'm from I've only ever seen co2 or pure nitrogen (for Guiness and the like). Another advantage ist that Nitrogen is cheaper, or so I heard.
Never thought about the over carbonation issue but makes sense once you think about it
