Dunkin' flavored beer hits market

Dunkin' has a new kind of cold brew on tap. The company is partnering with Boston-based Harpoon Brewery to make the beer called Dunkin' Coffee Porter.

The beer is made with Dunkin's espresso-blend coffee. Harpoon says the Dunkin' coffee brings robust, "roasty" notes to the coffee porter.

The beer has an alcohol content of 6.0%.

It will be available across the eastern United States for sale in 6-pack bottles. Harpoon will also serve it on tap at its Windsor, Vt. and Boston breweries.
