I am very much a big beer guy!! Optimator is my number one beer!!!!

Other favorites:

Young's Double Chocolate Stout
Anything by Samuel Smith
Two-Hearted Ale.
Warsteiner Dunkel
Smithwick's
Most Sam Adam's stuff is pretty good.
Celebrator Doppelbock.
Rogue has a beer that is dark and has a caramel aftertaste. Almost like drinking a Rolo. I think it's fairly new. I will have to get the name of the brew and report back to you.

What do you like best?
