Now as I see I have three options for taking some kegged beer on such travels: vacuum ‘growlers’(horrible term!), mini growler kegs , or go the whole hog and get a 9litre corny

I’m leaning towards a couple of 2litre vacuum growlers and not bothering with a gas set-up, just use them like bottles. But then a 9 litre corny, kept cool, with a party tap and Sodastream bottle & regulator would be really cool…
What do you do in the way of mobile beer service???
Cheers,
Jamie
