This is classic MGP light whiskey. 99% corn, 1% malted barley, distilled to 160 proof then aged in used bourbon barrels. However, while Stitzel Weller was shut down, Diageo transported a significant amount of light whiskey distillate from MGP and barreled/aged the whiskey at the famed Stitzel Weller. While these casks weren't high proof for light whiskey (mid 120's), it is nevertheless classic light whiskey with an incredible history.
