Barrell Bourbon Batch 023 is a blend of 10, 12 and 15-year-old barrels. We focused on a balance of richness and depth from the older barrels. The blend mingled for a couple of months to heighten the lushness and complexity. Finally, we methodically layered in 15-year-old barrels to bring out notes of tropical fruit and angelica spice. The result is an evolving bourbon with layers of flavor.
