Show Notes

Big Chief heads to Denison, Texas, to visit Iron Root Republic Distillery, where a family of three — mother Marsha and her two sons Robert (Rob) and Jonathan Licorice — have been quietly redefining what American whiskey can be. Founded in 2014 after years of study, mentorship, and a fateful trip to Dry Fly Distilling in Washington State, Iron Root Republic earned global attention when their flagship Harbinger took Whiskey Magazine's World Whiskey Awards Bourbon of the Year for 2020. Big Chief sits down with Rob and Marsha to hear the full story: from a Christmas dinner announcement that changed everything, to a week spent tasting 19th-century Cognacs in France, to growing experimental heirloom corn in the front yard.

On the Tasting Mat:

  • Harbinger 115: Iron Root Republic's flagship bourbon, bottled at 115 proof, blended from barrels ranging 32 months to just over four years old. The mash bill features bloody butcher corn, purple corn, red flint corn, yellow corn, and a low-rye component, distilled in a pot still and non-chill filtered. Tasting notes include floral aromatics, peach, apricot, orange marmalade, baking spices, cinnamon candy, creamy vanilla, and a finish with a pop of spice. (00:01:48)
  • Promethean (Bottled in Bond, 100 proof): A recently bottled expression at 100 proof, repositioned as Iron Root's bottled-in-bond bottling. This release inverts the Harbinger mash bill, foregrounding red flint corn and rye. Tasting notes include dark fruit, dark tea, kettle corn, toffee, baking chocolate, vanilla, caramel, and a notably different finish from the Harbinger. (00:15:25)
  • Purple Corn Single Barrel (Euro Oak, 3 years, 121 proof): A single barrel expression made from a 100% purple corn mash bill, aged approximately three years in European oak, bottled at cask strength 121 proof. Tasting notes include honey, Swedish fish–style red fruit candy, vanilla, spicy jalapeño-infused honey sweetness, and a mouth-coating, salivating finish. (00:33:51)
  • Bloody Butcher Single Barrel (American Oak / Wavestave, ~32 months, 131 proof): A cask-strength single barrel at 131 proof made from a bloody butcher corn mash bill aged in American oak wavestave casks for approximately 32 months. This is the barrel selected by the YouTube Whiskey Tribe group at the Bastards Ball. Tasting notes include deep black licorice on the nose, rich oils, butter, caramel, toffee, warm leather, subtle oak, and an exceptionally dense, coating finish. (00:46:47)
  • Icarus (Purple Corn, Port & Islay Scotch Cask Finish, 107.2 proof): A limited, distillery-primary release made from Iron Root's purple corn mash bill, finished in a combination of an old Tawny port barrel (originally filled 1969, dumped 2016) and ex-Islay Scotch casks. Bottled at 107.2 proof and developed in collaboration with mentor Nancy Fraley. Tasting notes include light medicinal peat, cotton candy floral sweetness, cooked sugar water, port-driven richness, fruitwood smoke, and a thick, coating mouthfeel. (00:59:44)

Iron Root Republic is a testament to what happens when curiosity, family, and genuine craft converge. From heirloom corn grown in the front yard to a Sister City relationship with Cognac, France, that informs their distilling philosophy, Rob and Marsha Licorice show that the most compelling American whiskey stories don't always start in Kentucky. If you can get your hands on a bottle — and that's no small feat given how fast their shelves clear — don't hesitate.
