I know that when the food & wine festival is going, you can get all of the beers being offered during it. As far as the beer list that each county offers I have not seen it. Although I could take a decent shot...
Mexico - Dos Equis, Tecate, and Bohemian
Norway - Carlsberg is it...
China - Tsingtsao
Germany - Beck's Dark and seasonal, Franziskaner Weisse, Lowenbrau
France - Biere Kronenbourg 1664
japan - Krin, Kirin Ichiban
Italy- Peron
USA - Sam Adams, Bud / Bud Light
Morocco - Casablanca I think, might be called just Casa
UK - Bass, Harp, Stella, Tennents, Strongbow, Guinness and my fav Boddington's
Canada - Moosehead, Labatt's, and they had three regional beers in Le Cellier, but cannot recall which ones.
Also you can find Michelob Light and Michelob Ultra around at some of the kiosks.
Let me know what I missed!!!
