Hey everyone. I kegged my first beer last night and I'm pretty pumped. It's an Irish stout that we'll be serving for St. Patty's Day. I've done a lot of reading on this Forum and I belive have all my questions answered but wanted to summarize them here and make sure. Here's what I have:
1) Irish Stout
2) 40 degrees in Keezer
3) in Boulder, CO at about 5,500 feet
4) pushing/carbing with beer gas 75% nitro 25% co2
5) I have a stout faucet
6) Wanting about 2 volumes of co2 (I figure if it's too much carbonation I have time to take some out)
My question is the pressure. Looking at the Kegorators.com carbonation chart I apply 7psi at 40 degrees for about 2 volumes, however, I read on the BA's quality manual that you add 1 psi per 2000 feet above sea level which would add about 2.75 psi for 9.75 psi pressure and since I'm 25% co2 I multiply times 4 and get 39 psi.
Is my reasoning sound here?
Also, if I leave it alone, how long should I wait to pour a pint and check it out?
As always, thanks.
