At 118.4 proof, this expression is part of the annual Master's Collection series, which celebrates Master Distiller Chris Morris and Assistant Master Distiller Elizabeth McCall and their commitment to craftsmanship. Batch Proof is a celebration of Woodford Reserve's proprietary process - blending barrels into a batch and then bottling the whiskey at its actual proof, straight from the barrel. Batch Proof is crafted using the same grain bill and process as Woodford Reserve Kentucky Straight Bourbon.
