Just four months after releasing their first collaboration beer, Off Color Brewing and Side Project Brewing are at it again.

This time, the beer is Corybantic, a 6.6 percent ABV American wild ale that is brewed with pils, flaked wheat and special aromatic malts as well as galaxy hops. In addition, according to filings with the Alcohol and Tobacco Tax and Trade Bureau (TTB), the new beer uses a “Secret” ingredient, “Wine Barrel-Aged Water.”

This will be the second collaboration between the two breweries, with the first, Bière de Fantaisie (7 percent ABV) having been released in February. In addition, the two breweries joined forces with St. Louis, Mo.-based Perennial Artisan Ales to release ProCATStination, a 6 percent ABV Belgian-style saison earlier this month.

Corybantic will be brewed and bottled at Off Color Brewing in Chicago, Ill. and will be packaged in 750ml bottles. Emails sent to both breweries for additional details were not immediately returned.
