[4] Harpoon IPA quickly became a staple of the American India pale ale style and was found on tap at bars and restaurants in Greater Boston.

[9] Harpoon purchased the former Catamount Brewery plant in Windsor, Vermont, in 2000, expanding its brewing operations beyond Massachusetts.

[10] In July 2014, while then the twelfth-largest craft brewery in the United States, the company became employee-owned via the creation of the Harpoon Employee Stock Ownership Plan.

[11] In 2015, for the first time since its founding, Harpoon Brewery suspended production of its beer citing an imminent blizzard.

The deal involved Harpoon assuming possession of the Long Trail, Otter Creek and Shed brands.

Other offerings include Rec League, a New England Pale Ale, Big League, a big and juicy IPA, UFO Light Force, a light white, UFO Maine Blueberry, and selected Clown Shoes beers.

[21] The brewery also introduced a custom blood orange IPA in partnership with the Davio's restaurant in Boston's Seaport District.
