it all tatses the same, dont even bother, just go to the bottle shop and pick whatever is cheapest.
on a more serious note, i have no idea where you would go for such a service, apart from decent bottle shops.
I am rather interested in this too, as i would like to buy some asahi that is ACTUALLY MADE IN JAPAN ratehr than thailand, and all of the other import beers that are made under liscence in a country other than their country of origin.
