I have been searching these forums and others for some advice on moving carb'ed beer from a 19L pepsi keg to another 19L Pepsi keg, without making a huge f'ing foamy mess. One other catch and the reason I want to do it, I want to run this carb'ed Cream Ale through a Pentek 158008 filter system to clean it up. I have used this filter on my last batch of lager and it did clear the beer up nicely and was fairly easy to use, however the lager was coming from the secondary and not already carbonated.
From what I found so far, I need to create a closed pressure system by keeping the the pressures in both the full and empty kegs equal (easy part). Then use the relief value in the empty keg to decrease the pressure which in theory should start the beer flow from the full keg to the empty. This all makes sense but the filter system is the unknown and after the beer starts flowing, do I disconnect the gas line to the empty keg so the pressure remains lower then the full?
Hmmmm......anyone have any experience with moving carb'ed beer through a filter? Or should I save myself the headache and just drink the existing beer in one sitting, make a new batch of cream ale this weekend and start over

Thanks, Chicanuck
