During prohibition, bootleggers would transport liquor in cars modified to drive faster, corner better, and handle the weight of the bottled spirits. Early on, the preferred engine was the 354 cu in straight 6, or ‘Big Six’. It was powerful, smooth, and consistently dependable, much like our bourbon. Big Six Double Oak is aged in new American Oak Barrels, then finished with toasted French oak spirals to create a soft, rich flavor with notes of vanilla, caramel, baking spice, and oak tannins.
