The truth is that the beers I'm hearing about not travelling are your pretty dodgy national or regional brewers' beers, which are mass produced with basic ingredients and sent to pubs whose landlords aren't really bothered about the quality of their ale.
The fact is that all ale needs a period of rest after their journey to the pub, whether it be from the pub's own backyard microbrewery; a trip of a few metres, or a long journey by wholesaler's lorry down the motorway. It then needs careful handling and conditioning, and should be tasted by the staff before serving, to check it's ready. The 'travel' part of a beer's life really should be irrelevant.
The next time someone tells me beer X doesn't travel well, I shall tell them firmly not to drink crap beer in crap pubs.
