The 16th edition of the Parkers Heritage Collection consists of 67% 13-year-old Kentucky Straight Bourbon Whiskey that has been double-barreled and then blended post aging with 33% 15-year-old Kentucky Straight Bourbon Whiskey. The 13-year-old Bourbon was aged on the 5th-7th floors of Rickhouse Q and was then re-barreled in new American white oak barrels with a level 3 char for 4 weeks. Then, it was later blended with 15-year-old Bourbon aged on the 2nd and 5th floors of Rickhouse II. The double barreling of the 13-year-old Bourbon helped to bring out even more oak and spice notes from the barrel, while later bending it with older bourbon helped to create a unique, bold, and balanced flavor profile. At bottling, the liquid was uncut and non-chill filtered to preserve the complex flavors of this truly unique Bourbon.
