The final release in the Partner Ships Series for 2016 will bring together Baltimore, Md.-based Heavy Seas Beer and Escondido, Calif.-based Stone Brewing Co.

The resulting beer will be named Imperial Brown IPA, which as its name suggests, is a 9 percent ABV imperial brown IPA brewed with Centennial, Chinook, Citra, Palisade and Simcoe hops as well as blackstrap molasses that is being added into the kettle. This is an update from the original version of the beer, which was going to be a 7.5 percent ABV brown ale brewed with brown, crystal and pale malts as well as centennial and Simcoe hops.
