Look, if it's draught beer that you are on about, then you are all full of crap.
It's true to say, that if you drink the beer from where it originates, then you are getting the correct taste, texture, flavour, whatever.
"Good old blighty" is famous for trying to make other peoples beer and we end up with piss!.
Heineken, in Amsterdam, is vastly superior to the dish water mainly served up here.
Carlsberg in Copenhagen, is excellent, elsewhere it tastes horrible.
The UK also has "Park Royal" piss (Guiness brewed in West London). It only has a very passing resemblance to that "nectar from the banks of the Lifey" i.e. Guiness brewed in Dublin - now that really is "good shit".
I never tasted any American beer that I could get to like, the original Budweiser (is it Czech, Hungarian or Polish, I forget) is far superior to the insipid US version bleagh!
The same can also be said for Whiskey. Malt Scotch/Irish is marvellous, whereas those blended ones (Johnnie Walker, teachers, famous grouse to name but a few) are foul.
But, IMO, the US has a little "trump card" up it's sleeve with "whiskey" in that I much prefer a bourbon whiskey, to either Scotch or Irish, and yes, Jack Daniels, always seemed to taste so much better when drunk in the US than here!
So maybe the answer is to travel, enjoy the local flavours of wherever, but don't try to relocate them, just enjoy the product at the time and the memory later.
As for the beer cooler device, way way too much hassle, just install one of those small camping cold boxes next to your PC or buy a very long extension cord for those "garden moments".

p.s. There's always the bottled originals to fall back on, carlsberg "elephant" beer - brewed in Denmark, yum yum or Heineken brewed/bottled in Amsterdam etc etc etc the list is endless!!!!!
