Yellowstone has been one of Kentucky's favorite whiskies since 1872. The Mellow Mash name has always been a Yellowstone exclusive, identifying only the very smoothest bourbon to bear the Yellowstone name. For 2020 we offer our selection from our very best barrels yielding our finest bourbon, aged seven years and finished in Armagnac barrels. Thoughtfully crafted in limited quantities for our most discerning drinkers. From our hearts to fill your glass.
