This Cellar Aged Bourbon Whisky is an annual limited release with the difference from Maker’s Mark, being that they use the same maturation process, but barrels are then moved into the distillery's limestone whisky cellar for an additional 5-6 years of ageing before being blended to taste and bottled. These first-of-their-kind limestone cellars provide a consistently cool environment that’s protected from the extremes of the Kentucky climate. This slows down the tannic impact that occurs during maturation while allowing the bourbon to develop a richer, more complex flavour that stays true to the founder’s taste vision of bourbon without the bite. The 2023 Cellar Aged expression blends 11- and 12-year-old bourbons bottled at cask strength.
