Show Notes

Todd Ritter and Jim Shannon are back at the Corner Rick House in Frankfort, Kentucky, diving deep into one of whiskey's most exotic finishing woods — Mizunara oak. Native to Japan and harvested only from trees aged 200 to 500 years old, Mizunara (Quercus crispula) barrels can cost anywhere from four to six thousand dollars each, making them one of the rarest and most expensive casks in the whiskey world. The duo explores how four very different American whiskeys — from craft operations to storied Kentucky distilleries — interact with this sandalwood-and-coconut-forward Japanese oak, proving that the same finishing wood can yield wildly divergent results depending on the base spirit, age, and fill history of the cask.

On the Tasting Mat:

  • Four Roses Experimental Series #001 Mizunara Cask Finish: A first-ever experimental cask release from Four Roses, this six-year OBSK Kentucky straight bourbon (65% corn, 35% high rye, 5% malted barley, K yeast strain) is bottled at 104 proof in a 375ml format with an MSRP of $55. The nose is bright, floral, and citrus-forward with lemon and green apple; the palate opens with a wave of sweetness, baking spice, and a striking citrus note reminiscent of lemon heads, finishing with an Arnold Palmer-like tea-and-lemonade quality. (00:30:00)
  • Starlight Mizunara Reserve Small Batch #0003: An annual limited release from Starlight Distillery in Indiana, this 110-proof eight-barrel blend marries two mashbills — a three-grain corn/rye/malt and a four-grain corn/rye/malt/wheat — both from sweet mash recipes, finished six to eighteen months in Mizunara. The nose is subtle and requires coaxing, offering darker caramel, sandalwood, and incense-like depth. The palate delivers a memorable toasted coconut and piña colada quality alongside baking spice and darker fruit, with a rich mid-palate that rewards patience. MSRP $150. (00:13:22)
  • Hard Truth Barrel Finish Reserve Series Mizunara Finished Weeted Bourbon: From Hard Truth Distillery in Nashville, Indiana, this 116-proof weeted bourbon (69% corn, 19% wheat, 12% malted barley) delivers one of the most aromatic noses of the session — a vibrant, evolving fruit medley of raspberry, strawberry, light cream, and peach that practically leaps from the glass. The palate rolls across the entire mouth with creamy berry sweetness before an unexpected burst of spice on the back of the palate, finishing long with a persistent, satisfying sizzle. MSRP approximately $75. (00:27:32)
  • Dark Arts Whiskey 7.5-Year Mizunara Finished Bourbon (Bourbon on the Banks Pick): A Bourbon on the Banks exclusive private selection from Dark Arts Whiskey in Lexington, Kentucky, this 7.5-year MGP high-rye bourbon (60% corn, 36% rye, 4% malted barley) is limited to just 72 bottles. The nose opens with a fresh, slightly minty brightness layered with cooked apple and a distinctive sawdust-and-sandalwood Mizunara character suggesting a first-fill barrel. The palate is velvety and full-mouthed with a sticky, lingering texture, coconut on the finish, and a gentle white pepper mid-palate spice that builds slowly. (00:43:37)

The Corner Rick House session wraps up with all four glasses back on the mat for a final comparative lap, confirming just how dramatically the same finishing wood transforms depending on the vessel, the base whiskey, and the hand guiding the selection. Todd and Jim also reflect on a recent listener meetup at the Corner Rick House — joined by Bourbon Roadies from Ohio, Florida, and Georgia as well as members of the Frankfort Bourbon Society — and preview upcoming events including Bourbon on the Banks. Whether you are a longtime Mizunara devotee or approaching Japanese oak for the first time, this episode is a masterclass in how one rare cask can tell four completely different stories.
