This year, Darkness will be coming in the fall.

According to a post on Surly Brewing Co.’s website, it will again be releasing Darkness Russian imperial stout on Darkness Day, which this year will fall on Oct. 21, one week later than last year.

The Minneapolis, Minn.-based brewery’s Russian imperial stout is brewed with pale ale, golden promise, crystal, dark crystal, oats, black, chocolate, and roast malts, as well as Amarillo, Columbus, and Simcoe hops. In addition, Surly has historically released a barrel-aged version of the Russian imperial stout on a later date than the regular version.

The series started in 2007 and has featured a different monster on the bottle every year since it was first released. This year’s monster will be Baba Yaga, “a fearsome, forest-dwelling witch with a hooked nose and iron teeth, capable of casting a spell that makes this beer irresistible to all who taste it”, according to Surly. “In Russian folklore, Baba Yaga can be villain or comfort. Featured artist Adam Sward has created an ambiguous depiction of her and her cauldron of Darkness.”

Past years’ label art have included depictions of “a screeching bat nightmare,” a mummy, the Devil, a vampire, a werewolf and the Grim Reaper, among others.

According to Surly, this year’s Darkness Day will be held on Oct. 21 at the brewery’s Brooklyn Center location, and the beer will be packaged in 750ml bottles.
