So, I use the chart in Papazian's Homebrewer's companion to determine vols of Co2 along with temp and psi, etc.
My beer is at about 34 degrees - I can't get it any warmer this time of year in my garage . . . my kegerator is turned as high as it will go. Well, I have my psi set at about 14-15, but the CO2 level does not seem all that high. The beer is just about how I like it, but according to charts, I should have a bunch of CO2 in solution - more, in fact, that I tend to like. Is something wrong?
One more thing - the beer tends to seem more carbonated as I reach the bottom of the keg. Currently, I have two brand new kegs on and the carb level seems about perfect. The last gallon or so of the last two seemed very carbonated. I assume that his is due to the greater head space in the keg and more CO2 going into solution as a result.
Does this seem about right? If so, shouldn't I back off of the CO2 as the keg is emptied?
