For longtime fans of Surly Brewing, the company’s annual Darkness Day has become something of a homecoming. The event, which celebrates the seasonal release the brewery’s highly coveted interpretation of a Russian imperial stout, has historically been held at Surly’s original location in Brooklyn Center. This year the party’s surging popularity has relocated it to Wisconsin’s Somerset Amphitheater. The new grounds allow for vastly expanded possibilities. Now spread over an entire weekend, Darkness Day will continue to feature an authorized bottle share, as well as guest taps from a wide spectrum of local and national brewers. A fleet of food trucks will supplement the copious consumption of hops and barley. Contributing a scorching soundtrack, nine metal/thrash bands will command two stages, including Sick Of It All and Carcass. And in recognition of the lengthened commute from the Twin Cities, camping options are available and highly encouraged. For all the changes, though, the festival remains focused on fostering camaraderie around the launch of Darkness. Not only can partygoers procure bottles before the official Halloween release, but three variant styles will also be offered exclusively to attendees. Find tickets and more info at surlybrewing.com.
