Favorite hands down because I can't get it all the time: Stone Russian Imperial Stout. Local specialty beverage store is getting some in, had to have them set aside a dozen for me. Hopefully I can hide a few from myself to age.
If I"m feeling hoppy, Dogfish Head 120min IPA or Rogue Hoppy Froggy IPA when I visit home back in Seattle.
When its blisteringly hot and I just want to down as much liquid as I can: Moosehead.
