The 2017 Birthday Bourbon barrel selection was drawn from different warehouses and floors. 93 barrels matured together on the 4th floor of G warehouse, and were extremely spice forward. 27 barrels matured together on the 5th floor of K warehouse and contributed rounding sweetness to the blend. Quite a few barrels basked in the sun from both of these lots, showcasing the effects of maturation along an external wall.
