Buffalo Trace Distillery has never been shy about pushing the boundaries of what bourbon can be, and its latest release makes that clear all over again. The Kentucky distillery has officially announced Daniel Weller Spelt Wheat, the second entry in its Daniel Weller experimental series — a line built around a simple but fascinating question: what happens when you change just one grain?
The answer, at least this time around, comes in the form of spelt — one of the oldest cultivated wheat varieties on the planet — and a bourbon that took a full decade to reach the bottle.
What Exactly Is the Daniel Weller Line?
For anyone who hasn't been following closely, the Daniel Weller series launched in 2023 with its first release, Emmer Wheat. The entire concept of the line centers on the Weller wheated bourbon mashbill — the same recipe that has made the Weller name legendary in American whiskey circles — and then systematically swapping in different wheat varietals to see how that single change shapes the final product.
The series is named after Daniel Weller, the grandfather of William Larue Weller, who settled in Kentucky in 1794 and brought with him a family tradition of distillation deeply rooted in American barter culture. He operated and leased his still to local proprietors, helping expand access to spirits in the region and cementing distilling as a cornerstone of the Weller family's identity. His work laid the groundwork for what would eventually become one of the most recognizable names in wheated bourbon.

Each bottle carries a nod to that history. The 750ml glass bottle features a unique compass stopper, and the coordinates of Daniel Weller's farm near Botland, Kentucky are inscribed beneath it.
Why Spelt?
Spelt is not a grain most bourbon drinkers will find in their glass very often. It has been cultivated for thousands of years, primarily across Europe, and has historically been tied to small-scale traditional farming and artisanal baking rather than commercial whiskey production. That rarity is part of what made it interesting to the team at Buffalo Trace.
Spelt is known for bringing a subtle sweetness and a gentle nuttiness to whatever it touches. The distillation team was drawn to it not just for those flavor qualities, but because of what it represents historically — one of the earliest grains ever put to work by human hands. That kind of deep agricultural heritage fits naturally with a series designed to honor the origins of bourbon making.

In this release, spelt takes the place of rye as the secondary grain in the mashbill. That's a meaningful shift. Rye typically brings spice and sharpness to a whiskey. Spelt, by contrast, leans softer — it builds on the smooth, round character that Weller bourbons have always been known for, while adding its own distinct personality to the aroma, texture and flavor.
Letting the Grain Do the Work
One of the more interesting things about how this bourbon was made is what the distillery chose not to do. There were no specialized barrel treatments. No unusual finishing techniques. No extra variables introduced to complicate the experiment. The whole point was to hear what spelt wheat sounds like on its own.
Master Distiller Harlen Wheatley put it directly: "Rather than leaning on barrel innovation, we chose to strip the process back and let the wheat speak for itself. By avoiding specialized barrel treatments and techniques, we were able to focus on how spelt wheat's natural sweetness and distinct character influence the Weller mashbill. Its nuanced profile makes it ideal for experiments where the grain's personality is meant to shine."
That discipline — pulling everything else back so one ingredient can step forward — is harder than it sounds. Distillers often reach for process variation to add complexity. Here, the complexity was expected to come from the grain itself, after ten years sitting in a barrel.
Ten Years in the Making
Daniel Weller Spelt Wheat is bottled at 94 proof and spent a full decade maturing before it was considered ready. That's not an arbitrary number. According to Buffalo Trace, ten years is when this particular bourbon hits its ideal flavor and balance. The time in the barrel allowed the grain's character to fully develop and integrate, rather than sit on top of everything else.

The nose opens with that nutty, biscuit-forward quality you'd expect from spelt. From there it moves into freshly baked cookies, clove, cinnamon and nutmeg, supported by light fresh fruit, subtle leather and underlying notes of butterscotch, caramel, vanilla and oak.
On the palate, dried fruit and a gentle sweetness come forward, layered with baking spice. There's also a restrained floral, tea-like quality that adds a dimension you don't often encounter in bourbon — something almost delicate sitting alongside the richer notes.
The finish is long and composed. It carries soft fruit, nuttiness and light spice before settling into a fading, lingering sweetness that doesn't overstay its welcome.
For longtime Weller drinkers, this is a clearly different experience. It shares the family DNA — the softness, the approachability, the absence of rye's bite — but the spelt grain pulls the whole thing in a direction that feels genuinely new.
A Bigger Picture for the Weller Legacy
The broader Weller portfolio has become one of the most talked-about collections in American whiskey. It includes Weller Special Reserve, Weller Antique 107, Weller 12 Year, Weller Full Proof, Weller C.Y.P.B., Weller Single Barrel and the annually released William Larue Weller — one of the most sought-after bottles that comes out each year as part of the Buffalo Trace Antique Collection.
The Daniel Weller experimental series sits apart from all of that. Where the rest of the Weller lineup represents the refined, established expression of a wheated bourbon tradition, Daniel Weller is explicitly about asking what else that tradition could become.
Brand Manager Charley Costa Jr. framed it this way: "Daniel Weller set a standard for ingenuity that still guides us today. This line reflects that same pioneering mindset. By experimenting with distinctive wheat varietals like spelt, we're honoring Daniel Weller's legacy while challenging ourselves to explore new dimensions of flavor. Each release is an opportunity to connect our history to the future of American whiskey."
That's a statement worth taking seriously given what Buffalo Trace has built over the years. The distillery dates back to 1775, holds National Historic Landmark status and has won more than 1,000 awards across its portfolio. Its George T. Stagg was named World Whiskey of the Year for 2022. These aren't people who experiment for the sake of a press release.
What It Will Cost You — And Whether You Can Find It
This is where the conversation will get complicated for most people. Daniel Weller Spelt Wheat carries a suggested retail price of $549.99 for a 750ml bottle, with state taxes varying on top of that. Distribution begins in March 2026, shipping to select retailers, bars and restaurants across the country in limited quantities.

Limited quantities from Buffalo Trace on a Weller product at this price point means the secondary market will almost certainly have other ideas about what this bottle is worth. Anyone who wants to actually drink it rather than flip it will need to move quickly and know the right places to look.
For those who can track one down, this is a bourbon with a clear identity and a clear purpose. It's not trying to be the most complex whiskey ever made. It's trying to answer a specific question about what one ancient grain brings to a well-understood recipe — and after ten years of patience, it seems Buffalo Trace is confident it found a compelling answer.
The Broader Experiment Continues
With Emmer Wheat in 2023 and Spelt Wheat arriving in 2026, the Daniel Weller series is still in its early chapters. Each release is designed as a standalone experiment, but together they're building a record of how different grains shape a familiar bourbon foundation. That's genuinely useful information for anyone who cares about what ends up in their glass and why.
Whatever grain comes next, the approach will likely stay the same — strip everything back, change one thing, and pay attention. It's a methodology that respects both the history behind the bottle and the curiosity of the people drinking it.
