Any fresh, well hopped IPA works for me, good ones of late: Tremont IPA, Middle Ages Im Paled Ale, Hooker American Pale Ale, Southern Tier IPA, Magic Hat High PA
That being said I do like an ocassional stout or porter. Sierra Nevada, Magic Hat, Ipswich, Southern Tier all make good ones.
One of my favorite all around beers lately is Shipyard Export Ale.
Fruit beers not only suck, they are NOT BEER!
