I brought a few bottles of Bigfoot home from the States last summer. Incredibly bitter stuff. I'd waited years to try an American barley wine and it didn't disappoint. If you have the will power, it's probably best to lay down a bottle or two for a couple of years.
I gotta give that bigfoot a try if they still have some. We're gonna be doing a brew this weekend (if H&G deliver that is), so a it'll be a good time to sup some Sierra Nevada for inspiration. I don't think I've had [b:22m5ejnm]any[/b:22m5ejnm] of their beers yet!
