So I got a second keg for the forth of july so I could have my belgian wit and apfelwein on tap, I started carbing the apfelwein with set it and forget it about a week and a half ago and just got the wit in the second keg to start carbing using shaking. My question is since I only have a single gas line hooked up to one at a time do I need to worry about one keg loosing some of it carbonation while it is sitting off the gas?? Sorry if this is a dumb question but it seems like my apfelwein is a little lower on carbonation than now than when I hooked up to the wit. Also is there an easy way to serve both kegs without haveing to connect and disconnect the gas line each time, with out buying another regulator??
