Well, I'll tell you something. Running down American Beers, and especially Budweiser, is something of a national obsession. But a lot of people who knock Bud and then rave about some Strawberry Blonde sticky-sweet swill...well, they ain't beer drinkers! Bud is a decent pilsner, with a nice hoppy start and very smooth finish, and if you're having more than one, its an easy beer to stick with. And, although I think Guinness is great beer, one is usually plenty for me.I like a lot of pilsners and lagers, and find that the Mexicans are making some of the best erst-while "German" pilsners. I like Tecate and Dos Equis, but Bohemia is one of the best beers obtainable. I like these beers with a fresh lime slice. Sue me.
Among German beers, I like St Pauli and Becks, but their very hoppy taste and bitter finish make them a bit stale when drinking more than one or two.
Canadian beers...ah well. I have had a few local beers that were good, but the majority (Molson, Labatts, Moosehead) I find characterless.
I don't like lemon, honey, strawberries or chocolate in beer. I had a red pepper beer once that had a nice sharp taste.
I like many English "Best Bitters" that I've had, but they taste better pulled from the keg, and seem to lose flavor on canning.
New Zealanders, I think you have a nice beer in Steinlager, although I've noticed some fluctuation in quality.
The worst beer I've ever had was a Belgian beer called Celi's from somewhere in Texas. It had the distinct taste of rotting apples.
