To ensure that no other Bourbon in the world tastes like Belle Meade Bourbon, they created a proprietary blend using two different high-rye content mash bills and two complementary yeast strains from barrels aged between 6 to 8 years. Each batch of the proprietary blend consists of just 4 barrels and creates the signature flavor profile that makes Belle Meade Bourbon the award-winning Bourbon of choice for the discerning whiskey drinker.
