If it's a 'back up party beer' to boost the beer levels then some cheapy PET bottles will suffice don't you think?
I've used them in the past to store cheap n' cheerful/experimental brews that i knew wouldn't be hanging around long enough to oxidize like plastic bottles do over time.
I'm sure the Firehouse crew could muster enough for you quickly - this is a
geniune emergency after all!
Plus if you use the 3 litre ones (for easier bottling of course) it just means you have to steadily pour 5 pints at once to avoid the sediment mixing up into the rest of it.........
