I am a beer fan. I've tried many beers, and have many more to go. I am trying not to become a beer snob (much easier than with wine, which I have given up entirely), but I'm sad to say that some of the American mass-produced "label" beers really are lower quality by comparison. It's not necessarily a bad taste, just watery and less flavorful. I think beers like Budweiser are good for barbecues and even to put *on* the barbecue for flavor. I won't refuse to drink them, but I'll always prefer the better beers. And Americans are perfectly capable of making them. Most local microbreweries have something good to offer, and Samuel Adams provides a nice variety.
As far as foreign beers go, Europeans (specifically Germans) do it better than anyone in the world. Outside of Europe, Corona, LaBatt, and Fosters are pretty good; so are Asahi, Sapporo, Tsingtao, Harbin, and Singha for your Asian beers. Inside Europe, Smithwicks is a pretty good Irish brew (never liked Guinness), and Baltika is a good Eastern European brand. Heineken and Grolsch are good Dutch brews.
But nothing beats German beer. St. Pauli Girl, Becks, Warsteiner, Lowenbrau, and so many more. There is no finer liquid refreshment in all the world than German beer. Getting that first stein of Marzen on Octoberfest is better than opening presents at Christmas!

I hope to one day go to the real Oktoberfest in Germany.
