Parker’s Heritage 24 Year, the 10th Edition of Parker’s Heritage Collection is the oldest Bottled-in-Bond in the world. Bottled at 100 proof and non-chill filtered, this Kentucky Straight Bourbon Whiskey retains more of the natural esters and fatty acids that have matured in the barrel for almost a quarter of a century, providing a richer mouthfeel. Oak flavor is prominent with hints of cinnamon and vanilla, rounded out by a clean finish with a hint of chocolate.
