This is Maker's Mark® Bourbon in its purest form. Bottled at barrel proof and nonchill filtered, Maker's Mark® Cask Strength ranges from 108 to 114 proof depending on the barrels. Surprisingly smooth, this bourbon retains the signature, front-of-the-palate flavors of Maker's Mark® while amping up the notes of oak, caramel, vanilla and spice. Big oak, vanilla and smoky charcoal aroma. Longer finish on front of tongue with no roughness or bitterness. Richer, more robust flavors of spice, vanilla and smoke.
