I've had Bourbon Country Barleywine from Goose Island and I heard good things about Bigfoot from Sierra Nevada but aged. I'd imagine the latter being an easier beer to find though. As for Belgian ales, I would add Cuvee Rene from Lindemann (lambic, sour beer) into that list along with the other styles like Saison DuPont (saison), Duchesse de Bourgogne or Rodenbach Grand Cru (Flanders red ale), La Chouffe (strong pale ale), Duvel (blonde) then you go from there. I love how much variety exists with beers though I'm a bit turned off with the unobtanium stuff now. Anyway, for my 50 states 50 beers thing, I've decided to do a 50 stouts, sours and saisons for the simplicity of it all. If anyone is willing to ship me beers from their state (I will reimburse your costs of course), let me know!
