I must say that the amount of bubbly yellow fizz in this thread is slightly disparaging!

Some however have the right idea, some good Belgians mentioned already.
Guys, as a non US person, it almost pains me to admit that for variety and number of high quality beers, you are perhaps the best country in the world for beer (Belgium is there and thereabouts though with lower variety). This is not to forget that the average beer consumed in the US is dishwater of course.

I'll add some beers for you guys to try if you can get them there.
Try some of the BrewDog beers from Scotland. They can be a bit hoppy and bitter but are in the vein of a strong IPA.

Try Saison beers from Belgium. They are lighter than your average Belgian beer, though more hoppy (more aromatic than bitter). Really refreshing summer drink.
