Show Notes

Jim Shannon and Todd Ritter welcome listeners to another episode of The Bourbon Road Podcast and introduce a brand-new guest and a brand-new distillery to the show — Joe O'Sullivan, Master Distiller of Minden Mill Distilling out of Minden, Nevada. Located just 20 minutes east of South Lake Tahoe at roughly 5,000 feet elevation, Minden Mill is a true estate distillery, growing the majority of its own grain within three miles of the still house, malting its own barley on site, and aging its whiskeys in a climate-controlled rick house locked to the weather of Bardstown, Kentucky. Joe shares the full story of how the distillery evolved from its origins as Bentley Heritage Estate Distillery through its acquisition by Foley Family Wines and its relaunch as Minden Mill, and explains the extraordinary technology — including thermal oil calandria heating, wooden foeder fermenters, and Forsyths copper pot stills — that gives these whiskeys their unusually high ester loads, rich mouthfeel, and distinctly Western character.

On the Tasting Mat:

  • Minden Mill Nevada Straight Rye Whiskey: A four-year-old, 94-proof rye built on an 80% estate-grown winter rye, 10% wheat, and 10% barley mash bill. Distilled in a Christian Carl hybrid pot still, fermented in open wooden foeders, and aged in 36-month air-dried American oak barrels from Seguin Moreau cooperage, this rye delivers a nose of fresh grain and candied orange peel — evoking holiday citrus candy — with notes of horehound, white grape, and a bright, sweet mid-palate. The finish is clean and lingering. MSRP $44.99. (00:03:06)
  • Minden Mill Nevada Straight Bourbon Whiskey: A four-year-old, 94-proof four-grain bourbon made from 60% estate-grown heirloom Earth Tones Indian corn, 20% rye, 10% oats, and 10% malted barley. The starchy, anthocyanin-rich heirloom corn — described as closer to a potato than sweet yellow dent corn off the cob — ferments into a spirit with a cherry cola nose and a rush of cool, coating sweetness on the palate reminiscent of a vanilla cream float. The mouthfeel is exceptionally smooth and refreshing. Aged in the distillery's Bardstown, Kentucky climate-locked rick house. MSRP $44.99. (00:21:07)
  • Minden Mill Nevada American Single Malt Whiskey: A five-year-old, American single malt made from estate-grown and on-site floor-malted barley, distilled in Forsyths copper pot stills using a thermal oil calandria system that heats to 185°C — crossing the Maillard reaction threshold for heightened ester development. Matured in a combination of new American oak, used bourbon barrels, STR (shave/toast/rechar) barrels, and Oloroso sherry casks, all held in a rick house climate-locked to a weather station in Speyside, Scotland. The nose opens with honey, pear, apricot, and butterscotch, with a compote of white stone fruit. Rich and unctuous on the palate with a warm, fruit-forward finish. MSRP $59.99. (00:40:19)

Joe also previews several upcoming releases in development, including a cask-strength program, single barrel offerings, and a limited tasting-room exclusive floor-malted American single malt finished in house-made orange wine barrels. Whether you are a devoted bourbon fan, a rye enthusiast, or a passionate follower of the American single malt movement, this episode offers a fascinating window into what estate distilling at altitude in the American West can truly produce. Cheers, and we'll see you down the Bourbon Road.
