Dogfish Head 90 Minute IPA, Delaware, USA

It should be impossible for a beer that's been hopped for 90 solid minutes (an average IPA gets 60) to be delicious; in fact, each sip should be like snorting aspirin. This, however, is brewmaster Sam Calagione's specialty, and this confoundingly pleasant "extreme" beer is the purest expression of his skill. [$3/bottle;]
