Will-gotta agree with the Sammy Smith's Oatmeal Stout.
I think American beers are often written off way to soon by foreigners and Americans. yes, budweiser, coors, etc. is water in a can, but the microbrewerys in this country can't be beat.
Oregon and Vermont have the best microbrews in this country, with Vermont taking the cake. Stouts, Porters, the closer to tar the better for me.
My favorite of all is Rock Art Brewery's Stout in Vermont. Many of you out here haven't had it, but if you like stout, this is a winner. Its not served outside of Vermont, and even there you can only get in in 5 gallons, barrrels, and growlers (spelling).
