One thing necessary to understanding Surly Brewing Company is to know that the brewery’s head brewer Todd Haug is just as famous for his guitar work in the speed-metal band Powermad as he his famous for his beer. Along with the brewery’s founder Omar Ansari, Surly’s speed-metal approach to the brewing business defines the brewery and permeates everything the brewery produces. Every year, Surly commissions a different local artist to contribute artwork for the brewery’s three annual limited-edition series’ of beers: Surly Darkness (a Russian imperial stout), Surlyfest (the brewery’s Oktoberfest-inspired rye beer), and an annual experimental numbered series that is devised by Todd. This year’s Surly “Five” was a 100% Brettanomyces-fermented brown aged in used red wine barrels labeled with a pentagram. Not your average beer. But nothing Surly makes is average. Their fan base is rabid, ever-expanding, and will camp out at the door a day-and-a-half in advance for some of these beers.
