-cranking the gas to 10 or 11psi before i leave home on a half full chilled 19lt keg
-drive the 20mins and keep it cold in the ice, let it settle for 30 mins mabie
-dispense and put up with a little shampoo for a wile
-drink good for a wile
-put up with slow flow and no head at the end of the party (if i drink that much!)
good pour pressure on my portable line and tap is around 6-8 psi
dose anyone see that i would have any problems doing this?
G'day regan,
A half full keg has a $hitload of headspace that will quickly undermine your attempts to keep a decent pouring pressure going throughout - you'd be much better off with a nearly full keg of well carbonated icy cold beer. The size of the headspace and temperature will have a major impact on the keg's ability to keep serving without a CO2 top up....I'd chill the keg down to nearly zero degrees and gas it up well before you go. The problem is that pouring beer has the same impact on the headspace as a steady leak - you're not compensating with air like a draught system does, so it will be high pressure to begin with and then steadily (and quickly) drop down.
Rather than lugging a keg around, why not grab some beer line and a swag of 1.25L PET bottles - cut the beer line so that it's a few inches longer than the bottle is high, fit the line onto a picnic faucet (cobra) and manually fill the bottles with beer before you go. Keep the keg pouring pressure down to avoid foaming the beer in the line and the PET bottle and if you pour from a well carbed, very cold keg of beer, you should be ok with the bottled beer for the party - it works for me and you enjoy sediment free beer at the party without having to crap around with pouring pressure. I use 1.25L bottles instead of 2L since the bigger bottles will result in the last glass or two being nearly flat, unless you're slamming down the beers!
Cheers,
