I stumbled over a website a few months back of some guy that has a Kegerator at his house. I believe he had mentioned that he doesn't use Nitrogen to pressurize his Guinness, but a different gas. It was came cheaper than the Nitrogen, and the Guinness tasted just as good.
For the life of me I "cannot" find the page anymore!!!
I should have bookmarked it. Does anyone here have any idea which gas he could have been talking about?
Thanks
