Blue Run Emerald Single Barrel Rye Whiskey 4 Year 117.1 Proof is a Kentucky straight rye selected from Blue Run’s Emerald Single Barrel collection. Blue Run identifies the whiskey as contract-distilled by liquid advisor Jim Rutledge at Castle & Key Distillery in Frankfort, Kentucky, with the individual barrels selected by whiskey director Shaylyn Gammon. This exact 750 mL release is four years old and bottled at barrel proof without added water at 58.55% ABV (117.1 proof).
The single-barrel format preserves the character of one selected Emerald rye barrel rather than presenting a multi-barrel blend. Blue Run describes the collection as a set of ten distinct barrel expressions chosen to remain connected to the broader Emerald Rye profile while showing individual variation. The exact supplier-bound bottle carries the Emerald Single Barrel Rye wording, an emerald-green butterfly medallion, and a proof panel reading 117.1 proof and 58.55% ABV. No barrel name or barrel-specific tasting notes are assigned here because two barrels in the original collection shared this proof.
