Tonight at 7 PM Archie’s Iowa Rockwell Tavern (2600 W. Iowa) hosts a release party for Big Hugs Imperial Stout, which officially hits store shelves on Friday. The brew is the second collaboration between north-side brewer Half Acre Beer, which provides the stout, and Humboldt Park’s Dark Matter Coffee, which adds coffee brewed from Tanzanian and Sumatran beans. A rep from Dark Matter—whose coffee is only available brewed at Star Lounge Coffee Bar—says that a keg will provide free samples of the beer, though it’s expected to be tapped quickly; 22-ounce bottles will also be available for sale at $15 each.

The Reader‘s Philip Montoro sampled a previous incarnation of Big Hugs earlier this year at Stout Fest 2010.
