Stitzel-Weller Master Blender pick at the distillery. Accompanying notes describe a mash bill of 75% corn, 21% rye, and 4% malted barley, making it lower rye than typical Bulleit. This clearly shows, as it is far sweeter and tames the peppery rye spice into more of a pleasing clove and vanilla. Bought a bottle as it was both unique and enjoyable!
