Unlike Bourbon or Rye, which, by definition, must be aged in new oak barrels, the US1 Unblended American Whiskey is aged in a way that utilizes whiskey-soaked barrels to achieve a rich and unique flavor profile. Aromas of rich butterscotch, peaches and cinnamon. The used bourbon barrels brings more sweetness to the whiskey, but is balanced by the nice hit of spices.
