So I'm researching into all the kegging now as it's something that I really want to start doing. In addition to the typical CO2 setup I would really like to eventually build in the capability to do a nitrogen tap for my stouts and maybe others.
So, first of all, I get the impression that people first carb the beer with CO2 at low pressure and then use the beer gas to serve it with a stout faucet. What pressures do you guys use? And when you are ready to serve it what do you need to do, just disconnect the CO2 and connect it to the beer gas tank? Probably an easy question but I'm a newb so I just want to make sure I understand.
Second question is about the tank. I hear some people use CO2 tanks with CO2 regulators and then use an adapter. Is that cheaper or better option than buying a nitrogen tank with a nitrogen regulator? I don't fully understand that whole thing just yet. Or is it better just to call the local gas suppliers and ask what they use and maybe rent one?
Thanks for any advice!
