Show Notes

Jim Shannon and co-host Brian Hyatt welcome Lee Tatum, spirits industry veteran and VP of Sales at Interstave, to the Bourbon Road bar for a fascinating deep dive into barrel alternative oak and finishing innovation. Lee brings three decades of wine and spirits experience — including stints at Brown-Forman (Woodford Reserve, Cooper's Craft, King of Kentucky, Slane Irish Whiskey) and Kentucky Owl — to his current role at Interstave, a Napa-based company that has spent 40 years supplying the wine industry with alternative oak products and is now disrupting the spirits world. The conversation covers everything from how Interstave sources and seasons American and French oak in Napa's unique microclimate, to the science of new barrel equivalency, enhanced seasoning (think maple, sherry, port, brown sugar, and beyond), micronized oak powder, and the sustainability argument for using staves, cubes, chips, and blocks over traditional cooperage.

On the Tasting Mat:

  • Evan Williams Bottled in Bond White Label Straight Bourbon Whiskey (100 proof): Heaven Hill's workhorse bottled-in-bond expression — at least four years old, 100 proof, single distilling season, bonded warehouse. Light and approachable with caramel, vanilla, and a signature nutty, almond character that distinguishes it from its Heaven Hill siblings. An exceptional value at around $20. (00:03:20)
  • Evan Williams Bottled in Bond — Interstave French Oak Medium Toast / Maple Enhanced Seasoning Finish (100 proof): The same Evan Williams Bottled in Bond, transformed by six Interstave French oak medium-toast cubes infused with natural maple flavoring, resting in the sealed 750 ml bottle for eleven days at 100% new barrel equivalency. The nose bursts with maple the moment the bottle is opened, then settles into a more composed expression in the glass. On the palate, added sweetness arrives immediately from both the maple infusion and the toasted oak's wood sugars, with a cognac-like refinement and smoothed-out rough edges compared to the base whiskey. The finish is front-loaded at the eleven-day mark, with the deeper oak structure expected to integrate over the following weeks. (00:32:10)

Beyond the tasting mat, Lee paints a vivid picture of where the spirits industry is heading: sourced bourbon brands using Interstave products to differentiate on crowded shelves, craft distillers side-stepping the barrel shortage, and — most excitingly for home enthusiasts — the imminent launch of consumer-facing Cask Cubes, a $12 two-bottle kit that lets anyone become their own master blender. Whether you're running a distillery, building a brand on sourced stock, or just looking to elevate a $20 bottle in your home bar, this episode is full of actionable inspiration.
