Boston-based Harpoon Brewery and Dunkin’, Canton, Mass., are at it again, launching a series of new coffee- and doughnut-infused beers for fall. A trio of new beers, Harpoon Dunkin’ Pumpkin Spiced Latte Ale, Boston Kreme Stout, and Jelly Donut IPA, join Harpoon Dunkin’ Coffee Porter on shelves this September and mark the first time beers have been brewed with actual doughnuts from Dunkin’, the companies say.

After the positive reaction the Harpoon Dunkin’ Coffee Porter received from fans for two consecutive seasons, the brewers at Harpoon took it a step further to see what would happen if they brewed a beer made with Dunkin’s doughnuts, creating a new lineup that celebrates classic fall coffee and doughnut flavors:

• Harpoon Dunkin’ Pumpkin is inspired by the pumpkin latte. This “Spiced Latte Ale” is brewed with real pumpkin, pumpkin pie spices, and a splash of coffee. Light in color and easy drinking, Dunkin’ Pumpkin is a blend of autumn flavors, with a touch of espresso-like roast, and has an alcohol by volume of 5.2 percent
• Harpoon Dunkin’ Boston Kreme is a “Boston Kreme Stout” brewed with real Dunkin’ doughnuts and cacao nibs, which add extra dough-like and chocolatey notes to the creamy Dry Irish Stout. Dunkin’ Boston Kreme has an alcohol by volume of 4.3 percent.
• Harpoon Dunkin’ Jelly Donut is brewed with real Dunkin’ doughnuts and raspberry purée. This slightly hazy IPA has bright notes of jelly and citrus from the addition of fruit-forward Hüll Melon and Citra hops, it says. Dunkin’ Jelly Donut has an alcohol by volume of 5.7 percent.
• Harpoon Dunkin’ Coffee Porter is Harpoon’s first ever tribute to the Dunkin’ coffee that has helped keep Harpoon brewers running. This classic American Porter combines malty notes of chocolate, caramel, and toffee with the comforting and familiar flavor of Dunkin’ Original Blend coffee, the company says. Dunkin’ Coffee Porter has an alcohol by volume of 6 percent.

“We’re excited to elevate our collaboration with Harpoon this fall with the introduction of Harpoon Dunkin’ Pumpkin beer and the first ever Harpoon beer made with real Dunkin’ doughnuts,” said Brian Gilbert, vice president of retail business development at Dunkin’, in a statement. “We have no doubt the new doughnut brews, along with the rest of this new fall lineup, will bring the same moments of sweetness and smiles our coffee and donuts have created for 70 years.”

Dan Kenary, Harpoon chief executive officer and co-founder, added: “After more than two years and three seasons of collaborating with the Dunkin’ team, our fans have come to expect a delicious fall beer from us, but we wanted to give them something extra special this year. Our brewers have always been master innovators, but brewing beer made with real doughnuts was a first even for them. It’s hard to pick a favorite of the four recipes – just like it’s hard to pick a favorite donut from Dunkin’ – but we hope both our and Dunkin’s fans have a blast trying.”

Harpoon Dunkin’ Pumpkin will be available on draft and in bottled six-packs as well as in the new Harpoon Dunkin’ Dozen mix pack, which features three cans of each seasonal beer flavor. These limited releases will be available everywhere Harpoon is sold beginning in September.
