Stop wondering what a dogfish is (not to mention why the head in particular is worth singling out) and take a sip already. The brewers at Dogfish Head don't want you spending too much time thinking. They prefer you enjoy your day. And their beer. Since 1995 they've been brewing and, more importantly, experimenting with a variety of beers. They're up to almost 20 styles (including their flagship IPA), a few kinds of liquor, a restaurant, an inn and an unbelievable amount of good times.
