Limestone Private Cask Rye (375 ml)

Limestone Branch Distillery, founded in 2011 in Lebanon Junction, Kentucky by brothers Paul and Steve Beam — direct descendants of the Beam whiskey dynasty — was built explicitly to resurrect pre-Prohibition family recipes. The Private Cask program bottles individual barrels without blending, meaning every 375 ml half-bottle captures one cask's unfiltered character rather than a house average.

Lebanon Junction sits in Marion County, where the distillery draws from the same deep limestone-filtered aquifer that defines the broader Kentucky whiskey corridor — water naturally low in iron and high in calcium, which protects yeast health during fermentation and contributes to a cleaner, grain-forward spirit. The rye mash bill amplifies spice and herbal register that the local grain climate encourages.

Single-cask selection means no vatting, and the half-bottle format is designed for on-premise and collector access to barrel-level variation. The expression is bottled as a straight rye whiskey, meeting the minimum two-year oak aging requirement, with the private cask designation indicating no chill-filtration and no water reduction from barrel proof. New charred American oak is standard for the category and applies here.

What distinguishes this expression within Limestone Branch's portfolio is the 375 ml single-cask format itself — rare for a Kentucky rye at this price tier, offering barrel-specific traceability unavailable in their standard releases.
