Bottled at 108 to 114 proof, Maker's Mark Cask Strength amps up the front-of-the-palate flavors of Maker's Mark. In other words, it's Maker's with a lot more Maker's. But the higher alcohol content of our Cask Strength isn't the story here it's the taste. Maker's Mark Cask Strength has more of the rich oak, vanilla, caramel and spice that are the signature flavors of Maker's Mark.
