Flannel Friday from Harpoon Brewery is a 5.7% ABV hoppy amber ale celebrating New England's fall season. This collaboration with L.L.Bean blends American hops with subtle notes of roasted caramel and toffee from Maine-grown malt. The beer sits between a Brown Ale and Red IPA, offering a balanced, crisp, and approachable character.

Flannel Friday grew from a weekly tradition among Harpoon employees into an annual autumn celebration across the Northeast. Designed for everything from hiking to tailgates, the beer delivers a medium-bodied profile with American hop character that complements the transition into cooler months. Now in its 10th year, it has become a seasonal favourite among craft beer enthusiasts.
