So I've been brewing and kegging my root beer for a couple years now and have been brewing 5 gallon batches in my corny kegs in my kegorator. When I moved I've had a lot of people from back home want to purchase bottles of my root beer. I have all that I need to bottle, but with the aging that I do I can only produce 5 gallons every two weeks and the demand exceed what I can produce. So my question is this, does anyone have or know of a system that can force carb say, 20 gallons at a time? Or am I forced to buy more corny kegs and convert a freezer? I would really like to brew and force carb one 20 gallon batch in one container if I could. Any help or advice is greatly appreciated.
