Hi all,

On a recent camping trip I decided to bring along a few kegs, one was a oxebar 9L and the other a 9.5kg ball lock. They were at carbonated and then left at pouring pressure at 3C leaving my place. I popped them into an esky full of ice for the trip and we arrived a the campsite 3 hours later. I sat them upright while I set the tent up etc in their ice bath, burped the head pressure and started poured at 5psi. I was using a nukatap mini with a flow regulator and I proceeded to pour 75% foam for the next few hours - regardless of what I did to the flow control.

Does anyone else find this problem or is there something I've overlooked here? How do mobile keg bars deal with this generally (Kombi Keg etc..)

Thanks all
 
Pouring pressure is at 12-15 PSI,1.2 - 1.5 Bar approx.

If you carb at 12PSI and then reduce the pressure the beer loses dissolved Co2 as you reduce the liquid volume and then it foams.
