Brewed in collaboration with Harpoon’s favorite Massachusetts-based coffee and donut purveyor, Dunkin’ (formerly Dunkin’ Donuts), this porter is a tribute to the all the times Dunkin’ coffee helped them fire up the brew kettle in the morning. A handful of darker specialty malts and a touch of oats to give it a rich, chocolatey backbone with light notes of toffee and vanilla. After fermentation, the finished beer is then blended with a significant amount of Dunkin’s espresso blend cold brew to add extra layers of rich, roasty character.
