I was hoping some folks could help me with a kegging question. I am new to kegging, and just purchased two 3 gallon kegs to put into an Igloo cooler for a mobile kegerator. I will not be getting a full CO2 setup yet. For now, I plan on keg conditioning and dispensing with a paintball tank for mobility reasons. I need some sort of way of calculating how much DME to use to carbonate the beer inside the keg, factoring in only 3 gallons. I will use corn sugar for some recipes and I have a good calculator for that, but I can't find any calculator that factors in that I am keg conditioning and NOT bottling and tells me how much DME to use. Thank you!
