Michter’s 10 Year Kentucky Straight Bourbon is a limited-production, single-barrel whiskey from Louisville, Kentucky. Aged for at least a decade in specially selected new charred American white oak barrels, it is bottled at 94.4 proof (47.2% ABV)—a measured strength that allows its mature bourbon character to remain at the forefront.

Although the label carries a 10-year age statement, Michter’s notes that the whiskey selected for this release is often older. Rather than bottling on a fixed schedule, the production team determines when an individual barrel has reached full maturity. Each barrel is then released on its own rather than combined into a batch, making the single-barrel format central to the identity of the bottling.

Official notes describe a bold profile of dark toffee and caramel, joined by charred oak, maple syrup, and vanilla. Those flavors reflect the long maturation at the heart of this expression, balancing the sweetness associated with bourbon and the deeper influence of charred American oak.

Michter’s traces its historical roots to John Shenk’s Pennsylvania whiskey operation, founded in 1753 and later known as Bomberger’s before taking the Michter’s name in the 1950s. The brand was revived in Kentucky during the 1990s and now operates three locations in the state, including its distillery in Louisville’s Shively neighborhood.

Across its whiskey production, Michter’s emphasizes close attention to maturation. Its general practices include filling barrels at a relatively low 103 proof and using heat cycling during winter, followed by natural cooling, to create additional interaction between whiskey and wood. In this 10 Year Single Barrel Bourbon, that patient, barrel-focused approach finds one of its clearest expressions: a mature Kentucky bourbon released one carefully chosen cask at a time.
