In a rare, wide-ranging BourbonBlog interview posted above and on this link, Jefferson’s Bourbon cofounder Trey Zoeller joins BourbonBlog.com founder and Bourbon expert Tom Fischer to taste Jefferson’s Founder’s Reserve 20 Year Old—an exceptionally limited release of only 250 bottles.
The conversation goes far beyond the tasting. Known for his experimental approach and forward-looking ideas, Zoeller speaks candidly about the years before the bourbon boom, why he remains optimistic about the future of American whiskey and what may be ahead as Jefferson’s approaches its 30th anniversary as a brand in 2027.
He also looks back at sourcing whiskey and building Jefferson’s with his father, bourbon historian Chet Zoeller, while offering intriguing clues about the brand’s next chapter.
“I don’t know too many people—I don’t know if I know anybody—that has finished 20-year-old bourbon in the past.”
—Trey Zoeller
We agree: this is a rare bourbon and unlike anything else in the current Jefferson’s portfolio.
Jefferson’s Founder’s Reserve 20-Year-Old and Our Review
As BourbonBlog first reported when Jefferson’s Founder’s Reserve was revealed, the release is a Kentucky straight bourbon matured for a total of 20 years, including time finishing in French Bordeaux wine casks.
Only 250 bottles were produced. Each bottle was individually numbered and hand-signed by Trey Zoeller.
Jefferson’s has confirmed to BourbonBlog that the suggested retail price was $499.99. The first allotment sold out in less than a week, followed by a second and final online offering.
The bourbon is bottled at 94 proof.
Our Review of Jefferson’s Founder’s Reserve
As Tom Fischer tasted through Jefferson’s Founder’s Reserve with Trey Zoeller, the whiskey showed considerable age while remaining balanced, refined and alive with fruit.
Our tasting notes include:
- Nose: Deep cherries, dark fruit, mature oak, leather and baking spice
- Palate: Concentrated cherry, caramel, old oak, spice and a refined Bordeaux wine influence
- Finish: Long and polished, with lingering dark fruit, leather and mature oak
- Overall: Old in the best possible way—composed, distinctive and unlike anything else in the current Jefferson’s portfolio
This is not a bourbon driven by high proof or immediate sweetness. It develops gradually in the glass, with the Bordeaux finish adding richness and deep cherry character without hiding the mature whiskey underneath.
The Bordeaux Barrels for Finishing?
Zoeller could not confirm which Bordeaux winery supplied the finishing casks because Jefferson’s had not received permission to identify the source.
He did, however, suggest that the barrels may have been connected to a winery Jefferson’s had worked with on an earlier release.
That hint raised the possibility of Château Pichon Baron, whose casks Jefferson’s previously used for its Grand Selection Château Pichon Baron Cask Finish around 2017. Fischer happened to have a bottle of that earlier release nearby as part of his Jefferson’s collection and held it up during the interview.
Zoeller called it “a familiar product.” Whether Founder’s Reserve was finished in barrels from the same Pauillac estate remains unconfirmed, but the possible connection is an intriguing one.
From Jefferson’s Early Days to Ocean and Tropics
Zoeller also reflects on founding Jefferson’s with his father, bourbon historian Chet Zoeller, in 1997.
The bourbon business was very different then. American whiskey did not have today’s demand, prices or collectibility. Building an independent brand required finding quality whiskey, locating bottles and developing relationships throughout the industry.
When Fischer asks what it felt like when the bourbon boom finally arrived, Zoeller responds with characteristic honesty and humor:
“The feeling was great. I’m not going broke. I’m not going broke any longer.”
“People always say, ‘Great timing, Trey.’ Well, I was there a good 12, 13 years before things started to turn.”
—Trey Zoeller
By the time bourbon took off, Jefferson’s had already accumulated a strong inventory of barrels and spent years experimenting—giving the brand both the whiskey and the audience it needed.
In 2012, BourbonBlog broke the early story of the original Jefferson’s Ocean experiment, before its final packaging had even been completed.
The experiment placed bourbon aboard a research vessel, exposing the whiskey to movement, changing temperatures and conditions at sea. What began as a highly limited project eventually became one of Jefferson’s best-known collections.
Jefferson’s later explored a dramatically different environment with Jefferson’s Tropics Aged in Humidity, sending mature Kentucky bourbon to Singapore to experience sustained tropical heat and humidity.
Ocean explored movement and changing conditions at sea. Tropics focused on climate. Both reflect Zoeller’s continuing interest in how a barrel’s environment can influence the whiskey inside it.
Trey Zoeller Reveals What Could Be Next in the Jefferson’s Collection
During the BourbonBlog interview, Zoeller reveals that Jefferson’s has bourbon aging in additional climates and locations.
“I’ve sent some around to some really extreme locations that have some big swings in temperatures—both sides, cold and hot. We’re continuing to age those.”
—Trey Zoeller
Not every experiment has delivered the result Zoeller hoped for, but he says several have been “wonderful.” That process of testing, tasting and occasionally being surprised has driven Jefferson’s innovation from the beginning.
Where are those barrels aging, and which experiments could become future Jefferson’s releases? Watch the complete interview to hear Trey explain more.
The conversation also turns to Jefferson’s 30th anniversary in 2027. Zoeller reveals that he was heading directly from this BourbonBlog interview into a planning call for the anniversary release.
He stops short of revealing exactly what is being planned, but offers an enticing clue:
“It really hits to the core of Jefferson’s. It’s really on brand for what we’ve done in the past 30 years.”
After nearly three decades of sourcing, blending, finishing and experimenting with maturation, Jefferson’s has plenty of history from which to draw. A 30th anniversary release could celebrate one chapter of that story—or bring several of those ideas together.
The Bourbon Boom Is Evolving, Not Ending
While headlines continue to ask whether the bourbon boom is over, Zoeller offers a more optimistic, experience-based view of the current market.
“Spirits are undefeated. They’ve been around for thousands of years.”
—Trey Zoeller
Zoeller acknowledges that the spirits industry has been “kicked around” during the past year or two, but he does not believe bourbon is failing.
Instead, he sees continued excitement, strong social connections around spirits and opportunities for producers with great whiskey and distinctive ideas.
“As much as people like to write about doomsday, there’s a lot of excitement in the category. There’s a lot of excitement going on with bourbon.”
“You’re going to see such great expressions coming out because we’ve got such great inventories of bourbon around.”
—Trey Zoeller
Jefferson’s has been adapting and experimenting since long before the modern bourbon boom—from sourcing and small-batch blending to Ocean, Tropics and now a 20-year-old bourbon finished in French Bordeaux wine casks.
Founder’s Reserve celebrates Jefferson’s history. This conversation makes clear that Trey Zoeller is already focused on what comes next.
