Porters - Fullers London Porter is a favorite...Summit Great Northern Porter is another great one. Troegs Dead Reckoning is a good solid porter.
ESB - Fullers again, Rogue Brutal Bitter is pretty tasty as is Left Hand's Sawtooth.
Stouts- where to start? Got a favorite style (dry, sweet, double, RIS, plain old stout)? Grab one each of Bells stouts, Mikkeller BGB, Lost Coast 8 Ball is tasty, Rouge has some good ones as mentioned, Great Lakes Blackout, North Coast's Rasputin.
Yes, research is tough work but has to be done
