Well I really love just about everything Dogfish Head. But I will narrow it down to my top 5. However, they may change down the road since I have some 120 IPA, World Wide Stout, Olde School Barleywine and Bitches Brew in the cellar.
90 Minute IPA
Indian Brown Ale
Some beers by Stone. I also love Duck-Rabbit Rabid Duck and their Barleywine.
