This is Maker?s Mark?ÿBourbon in all its glory. By eliminating the proofing process normally used before bottling Maker?s Mark?, Cask Strength comes in at 108 to 114 proof. This surprisingly smooth bourbon retains the signature, front-of-palate flavors of Maker?s Mark ? while amping up the notes of oak, caramel, vanilla and spice. Richer, more robust flavors of spice, vanilla and smoke.
