I brewed an AG stout recipe and transfered the beer into my cornelius keg. I hooked up my CO2 tank and purged the head space. I am now trying to determine how to force carbonate this beer before I am ready to push it with my Nitrogen/CO2 tank.
Questions:
1. I was told that I should pressurize to only 1.2-1.5vols of CO2, but if I am serving with 32lbs of Nitrogen/CO2 (75%/25%), wouldn't I want to charge with 8lbs of CO2 since that would be equal to the partial pressure of CO2 before hooking up the mixed blend? - 8lbs@38°F is 2.2vols - what am I missing here? Thirty-two pounds has always worked perfectly in the past to push commercial stouts with a glorious cascade effect and perfect head - wouldn't I then pressurize to 8lbs of CO2 (2.2vols) for several weeks until fully carbed?
2. My CO2 tank is OUTSIDE the cooler (70°F), and the beer is INSIDE (38°F). If I want to charge my beer with CO2 at a pressure of 8PSI, do I have to adjust the pressure taking into account the temperature change? Do I set the pressure for the 70° temperature or the 38° temperature?
