Big Chief (Mike) flies solo down the Bourbon Road this week, welcoming Dr. Rob Arnold, Master Distiller at TX Whiskey / Firestone & Robertson Distilling in Fort Worth, Texas. Rob shares the remarkable origin story of TX Whiskey — how three men independently tried to open a Fort Worth distillery and ended up founding one together — and dives deep into the science behind their wild Texas yeast, isolated from a pecan tree on a ranch in Glen Rose. With ties to Dave Pickerel and a single-farm grain sourcing program rooted in Hillsboro, Texas, TX Whiskey is one of the most thoughtfully constructed craft distilleries in the country.

On the Tasting Mat:

  • TX Blended Whiskey: A sourced blend of bourbon styles and light whiskey, bottled at 82 proof for around $30. Vanilla-forward and approachable, with floral notes and a light, sweet finish that makes it an ideal summer sipper or cocktail base. (00:03:31)
  • TX Texas Straight Bourbon Whiskey (90 proof): A weeded bourbon mash bill of 74% corn, 14% wheat, and 12% malt, distilled from single-farm Texas grains and fermented with a wild yeast isolated from a pecan tree in Glen Rose. Aged nearly five years and bottled at 90 proof, it delivers prominent cinnamon, fig, dark fruit, baking spices, and a sweet grain character distinct from traditional Kentucky-style bourbon. (00:14:20)
  • TX Texas Straight Bourbon Whiskey – Sherry Finish: The TX Bourbon base finished in 20-year Pedro Ximénez sherry casks for eight to nine months, bottled at 101.6 proof. Deep amber in color, with rich molasses sweetness, dark fruit intensity, black pepper spice, and a warmth that drinks hotter than its stated proof. Priced around $60–$65 and currently most available in Texas. (00:40:47)
  • TX Texas Straight Bourbon Whiskey – Barrel Proof: The same weeded mash bill and wild pecan yeast, bottled straight from the barrel at 127.2 proof (batch-variable). Amplified caramel, brown sugar, cinnamon, allspice, fig, and cereal grain notes — described by Big Chief as reminiscent of Froot Loops, Honey Nut Cheerios, and Fig Newton cookies. A highly drinkable high-proof expression that represents the distillery at its most expressive. (00:47:06)

Rob also previews what's coming from TX: a cognac-finished bourbon joining the finishing series, a TX Rye Whiskey slated for late 2022 from single-farm Texas rye, a Bottled-in-Bond single barrel expression, and long-term plant breeding research aimed at developing grain varieties specifically optimized for whiskey flavor. If you're heading to Fort Worth, TX Whiskey Ranch sits on 100 acres about 10 minutes south of downtown — tours and tastings available. Find them at frdistilling.com and on Instagram at @txwhiskey.
