Rock Hill Farms Single Barrel BourbonRock Hill Farms Single Barrel Bourbon Another of Buffalo Traces fine single barrel bourbons, sharing a mash bill with Blantons, Elmer T. Lee, Ancient Age, and Hancocks Reserve. It is named for a stretch of farmland along the Kentucky River. While nearly all of Buffalo Traces top shelf premiums can be a little hard to find at the moment, this is not a limited release or particularly rare bourbon. It should be available in well stocked liquor stores
