Unlike Bourbon or Rye, which, by definition, must be aged in new oak barrels, Michter's US 1 Small Batch Unblended American Whiskey is aged in a way that utilizes whiskey-soaked barrels to achieve a rich and unique flavor profile. This allows mellow flavor with less intense smoky, charred influence found in bourbons. Instead, it has a sweetness, oak, mint & spice flavor. In late 2013, then Master Distiller Willie Pratt agreed to re-release this US1 Unblended American Whiskey after a nearly three-year absence from the market, deeming it "just right" and "the best it's ever been." Crucially, Michter's Small Batch Unblended American Whiskey never contains grain neutral spirits – hence its "unblended" distinction. It offers deep butterscotch and vanilla notes, hints of caramel and dried fruit with a ripened fruit finish. Enjoy!
