Jim Shannon and Todd Ritter hit the road to Lexington, Kentucky, pulling into the Turner Commons home of RD1 Distillery for a deep dive into one of the bourbon world's most science-forward wood-finishing programs. Joining them are RD1 co-founder Barry Brinegar and master distiller Jared Gollihue — a wood scientist with a PhD focused on barrel variation and oak chemistry — to walk through four distinctive pours that showcase just how far thoughtful finishing can push Kentucky straight whiskey.

On the Tasting Mat:

  • RD1 Sister Cities Kentucky Straight Whiskey (Mizunara & French Oak Finish): A blend of five- and seven-year-old straight bourbon and an eight-year straight rye, finished in both Mizunara oak sourced from Lexington's Japanese sister city Shinodaka and French oak from Deauville, France. Bottled at an accessible proof with 1,500 cases produced at $69 retail. Tasting notes include bright floral aromas from the aged rye, a measured Mizunara incense quality, light citrus, stone fruit, and a savory mid-palate with a round, balanced finish. (00:02:44)
  • RD1 10 Year Kentucky Straight Bourbon (Ambarana Finish, Barrel Proof): A carefully monitored limited release pairing a decade-aged straight bourbon with a deliberately light Ambarana wood finish, bottled at 117.78 proof and priced at $299. Jared sampled it twice weekly during finishing to guard against over-extraction. Tasting notes include earthy leather, dried oak, candy ginger, evolving baking spice, occasional flashes of anise, and a finish that shifts and changes the longer it sits in the glass. (00:19:06)
  • RD1 French Oak Finish Kentucky Straight Bourbon — Frazier Museum Single Barrel (Barrel Proof): A barrel-strength single barrel pick at 121-plus proof selected for the Frazier History Museum in Louisville, featuring RD1's signature French oak chains sourced from central France. Tasting notes lead with an inviting maple and French vanilla nose, baking chocolate, stone fruit, a creamy mid-palate, and a long warming finish with minimal harsh tannins. (00:39:57)
  • RD1 Red Oak Finish Kentucky Straight Bourbon — Kroger Chris's Pick (Barrel Proof): A sold-out single barrel selection at 122 proof finished in red oak, a species rarely used in spirits due to its lack of tyloses. Tasting notes open with a striking carrot cake and cream cheese icing nose layered with burnt orange citrus, followed by a rich, full palate and a clean finish with a whisper of fresh spearmint. (00:56:59)

Beyond the glasses, the conversation covers the science of tyloses and why red oak can't hold a barrel, how Mizunara demand compares to wine-world competition for French oak, Jared's path from UK horticulture and postdoctoral barrel-variation research to RD1's master distiller chair, and what's coming to the Turner Commons development in the next twelve months — including a 2,000-person amphitheater and Airbnb suites. If wood finishing is the frontier of American whiskey, this episode is a masterclass in why.
