Experience the cutting edge of the beer industry at the 16th annual Extreme Beer Fest, February 1 & 2 at the Seaport World Trade Center. Hosted by locally based BeerAdvocate, this three-session celebration of suds boasts nearly 400 brews (many of them festival exclusives) by more than 120 brewers from across the nation and various corners of the globe. New England is generously represented, with such regional faves as Maine’s Allagash, Vermont’s Long Trail and Foolproof in Rhode Island—not to mention Boston-area craft brewers like Night Shift, Jack’s Abby and Sam Adams—on hand. And in a tradition going back more than a decade, a special collaboration beer from BeerAdvocate and sponsor Dogfish Head is set to make its much-anticipated debut.
