I took the brewery tour at Deschutes (Bend, OR) in 2003. Mirror Pond Pale Ale is one I always drink when out West. Deschutes beers don't have distribution here in the East yet.
Weyerbacher (Easton, PA) makes some really good beers. I recently tried the Fireside Ale which was delicious.
Alaskan Amber is superb. It isn't sold here in the East yet though.
I've had Sweetwater 420 in Atlanta which is good.
Dogfish Head is high quality beer - they tend to be very hoppy as others have mentioned.
Rogue Dead Guy Ale (OR) is a favorite of mine.
Cisco Brewers on Nantucket, MA makes Whale's Tale Pale Ale which is yummy.
Allagash in Maine makes tasty beers as well.
A friend recommended a documentary about U.S. craft brewing called "American Beer: A Bockumentary" which I ordered, watched, & recommend. Learn more at the link below.http://sixhundred.com/films/american_beer/
You see me empty, Sir, do not pause and inquire, simply assume and refill.
