Exterior Illumination is an American Sour Ale brewed with cranberries, black currants, and Northern Michigan blue spruce tips. Dark pink in color with a bright pink head, this beer leads with aromas of tart currant and cranberry followed by hints of spruce. The English Brambling Cross hops keep the beer from becoming overly sweet and balance nicely with the tart berry flavor. Lighter in body with a dry mouthfeel, the spruce flavors are prominent in the finish adding a nice complexity. Exterior Illumination finishes tart and dry.
