A Keystone whiskey worth the drive to Bucks County

Using far fewer barrels than Donkey Kong would care for, Dad's Hat's Single Barrel Rye is limited to 65 bottles of hand-numbered and -dated 120-proof brown that features a "bold spice quality that’s backed by dry fruit notes, and caramel and vanilla flavors derived from charred oak aging". And unlike their local whiskeys in stock at the state store, it's only for sample and sale at their Bristol distillery.
