Old Knucklehead, a seasonal barley wine, was one of the first beers bottled by BridgePort, along with Blue Heron Pale Ale. The Old Knucklehead label has historically featured the likeness of local figures. The original batch No. 001 depicts BridgePort's then-landlord, Roger Madden. Other Old Knuckleheads have included Alfa Zinkus, Paddy Tillet, J.E. "Bud" Clark, Ray Grimm and Fred Eckhardt.
