FRANKFORT, KY (April 7, 2026) – Two of Buffalo Trace Distillery’s most ambitious and long-running experimental programs – the Single Oak Project and Buffalo Trace Distillery Experimental Collection – are debuting new releases this spring: Single Oak Rye Bourbon and Low Entry Proof Wheated Bourbon Whiskey. More than a decade in the making, these releases reflect the Distillery’s long-standing commitment to studying the variables that shape bourbon’s flavor as they “Honor Tradition, Embrace Change” in pursuit of creating the “world’s best whiskey.”

The Single Oak Project began in 1999, marking the Distillery’s first and most comprehensive experiment to date as it explored the impact of seven variables including mashbill, entry proof, aging location and barrel construction. The experiment comprised 192 unique bourbon barrels, each crafted from specific sections of hand-selected oak trees and filled with either a wheat or a rye recipe before undergoing varied maturation approaches. Consumers were invited to taste and evaluate the resulting bourbons, ultimately selecting Barrel #80 as the standout expression in 2011.

Today, Buffalo Trace Distillery builds on this landmark experiment with the introduction of Single Oak as a permanent, continuously-released whiskey brand. Its inaugural release, Rye Bourbon, faithfully recreates the precise mashbill and barrel aging conditions that defined the celebrated Barrel #80, offering enthusiasts the opportunity to experience the result of one of the industry’s most extensive bourbon studies to date.

The Buffalo Trace Experimental Collection, first introduced in 2006, will debut its 28th release with Low Entry Proof Wheated Bourbon Whiskey. This innovation explores how lower barrel entry proof influences wood interaction over extended aging, with the wheated bourbon distillate entered at 105 proof – noticeably lower than its traditional 114 proof. Inspired by historical records indicating that pre-Prohibition barrel entry proofs were often lower than modern standards, it represents a clear example of how the Distillery honors tradition while embracing change.  

“Experimentation has always been at the core of what we do at Buffalo Trace Distillery,” said Buffalo Trace Distillery Master Distiller Harlen Wheatley. “These releases represent years of patience, curiosity, and an unwavering commitment to learning. From the Single Oak Project, where we studied every detail of oak to better understand maturation, to our exploration of entry proof in the latest Experimental Collection, each experiment helps us further our understanding of how individual variables shape flavor and push the boundaries of what bourbon can be. We’re excited for fans to experience the results.”

More about Single Oak Rye Bourbon

The Single Oak Project began in 1999, when 96 oak trees were hand-selected from the Missouri Ozarks. Each tree was cut into a top and bottom section, yielding 192 unique pieces of wood and transformed into 192 individual barrels.

Seven variables were intentionally manipulated to study their impact on the final whiskey:

• Mash bill (wheat or rye recipe)
• Entry proof (105 or 125 proof)
• Stave seasoning (six or 12 months of air drying)
• Wood grain size (tight, average or coarse)
• Barrel char level (number three or number four char)
• Tree cut (top or bottom half)
• Warehouse type (wooden rick floor or concrete floor)

Single Oak Project Barrel #80 entered the barrel at 125 proof and was aged in oak harvested from the bottom half of the tree, featuring average grain wood, staves seasoned for 12 months and charred at a level four. The bourbon was aged in a concrete floor warehouse for eight years before bottling at 90 proof.

For the inaugural release of the Single Oak Collection, Rye Bourbon opens with a delicate yet expressive nose of caramel and vanilla, layered with light baking spice, toasted oak and subtle hints of orchard fruit. The palate is rich and beautifully balanced, unfolding in layers of toffee, vanilla cream and honeyed sweetness, accented by seasoned oak and baking spices. The finish is long and elegant, lingering with warm oak, soft spice and a mellow caramel sweetness.

Each 375ml bottling of Single Oak Rye Bourbon will be available in limited quantities through Sazerac’s national distributor network as well as the Buffalo Trace Distillery Gift Shop as of April 2026 at a suggested retail price of $74.99 (local taxes and fees apply).
