Old Man Winter is a blend of 8 year, almost 9 year-old, Indiana Bourbon with mash bill of Corn/Rye/Malt. This Indiana Bourbon sports a high corn content lending to the overall sweetness.  (My best guess is 75% corn/21% rye/4% malted barley). This is blended in equal parts with Preservation Distillery’s 6 year old Kentucky Pot Still Wheated bourbon.
