Boston-born magazine/website BeerAdvocate once again hosts its Extreme Beer Fest Boston at the Seaport Hotel & World Trade Center February 2 & 3, an event sure to attract lovers of the weird, creative, funky, complex and, yes, extreme end of the independent craft brewing spectrum. If you count yourself a member of that tribe, or you’re merely curious to see what it’s all about, then head down to the waterfront to sample imperial stouts, saisons, double IPAs and quadrupels from such acclaimed breweries as Portland, Maine’s Allagash Brewing Company; Everett, Massachusetts’ Night Shift Brewing; California’s The Lost Abbey; Florida’s Cigar City Brewing; and even international labels from Canada and Brazil. A trio of three-and-a-half hour sessions are available, so get your tickets to this popular, 15th annual extravaganza before they disappear.
