Beginning as fully matured Maker’s Mark at cask strength, expressions of Private Select are created by adding 10 custom finishing staves to each barrel and finishing them in our limestone cellar to extract more flavor. The 10 finishing staves can be any combination of five flavor profiles chosen especially for this program. With 1,001 possible stave combinations, each expression of Private Select has a customized finish and taste profile that is unique, yet undeniably Maker's.

Flavorful Whiskey Crafted Sustainably.
Maker's Mark is committed to shaping the future of bourbon through innovation and investment for the better of people and planet. As a B-Corp, Maker’s Mark is now part of a small but growing circle of global companies leading the way in creating a more sustainable future. Star Hill Farm is proud home to be the world’s first distillery to achieve Regenified Tier 2 certification, innovating in regenerative agriculture that’s as vital to the future of our land as the taste of our bourbon. We’re a founding member of the Common Ground 100M Acres Initiative, and pledge that 100% of Maker’s Mark grain be sourced from Regenified Certified farms by 2025.
