I've had a lot of good beers, but some I can't remember, since they were bought on a whim during trips. Which is a shame, because they were really good

Lost Abbey's The Ten Commandments
Elysian's Bifrost, Dayglow, and Immortal IPAs
McMenamin's Terminator Stout, Ruby, Irish Stout, and Black Widow Porter
Avery Brewery's Mephistopheles (easily my favorite beer)
Old Rasputin imperial stout
Sessions black
Blue Moon, particularly their winter abbey ale, summer honey wheat, and agave nectar brews
Alameda's Black Bear XX Stout, Irvington Juniper Porter, and Stubs Old Crow porter
Laurelwood's Space Stout
