Unlike Bourbon or Rye, which, by definition, must be aged in new oak barrels, this unblended American Whiskey is aged in a way that utilizes bourbon-soaked barrels to achieve a rich and unique flavor profile. Crucially, US 1 Unblended American Whiskey never contains grain neutral spirits � hence its �unblended� distinction. Often qualified as �just right�, the palate opens to oaky notes, smoke, flowers and spices.
