Heaven Hill Grain-to-Glass Wheated Bourbon – From Kentucky Soil to Your Glass

Updated → March 2026

Quick Take: Why This Bourbon Matters

Heaven Hill is one of the largest family-owned and operated distillers in the United States, and their Grain-to-Glass series is among the most ambitious transparency projects in American whiskey. The Heaven Hill Grain-to-Glass Wheated Bourbon takes that mission and wraps it in a soft, dessert-forward wheated mashbill that drinks dangerously well for a barrel-proof whiskey. At 121 proof, bottled without chill filtration, and aged for six years in the middle-to-upper floors of Cox's Creek rickhouses, this is a bourbon that rewards patience and attention. If you value knowing exactly where your whiskey comes from—right down to the corn seed varietal planted in the field—this bottle tells a story that very few producers can match.

What Is the Heaven Hill Grain-to-Glass Series?

Launched in 2023, the Heaven Hill Grain-to-Glass series represents a commitment to radical transparency in bourbon production. The concept began more than eight years earlier as the brainchild of Executive Chairman Max Shapira, who envisioned a whiskey line that would document every stage of production on the label itself. From the specific corn seed varietal to the exact rickhouse floors where the barrels aged, nothing is left to marketing ambiguity.

Each annual release in the Grain-to-Glass lineup offers a different expression—straight bourbon, wheated bourbon, and rye—allowing drinkers to compare how mashbill composition, barrel placement, and aging conditions shape the final product. The series has quickly become a favorite among enthusiasts who care about provenance as much as palate.

The Heaven Hill Grain-to-Glass Wheated Bourbon first appeared in 2024 as the inaugural wheated entry in the lineup. It immediately drew attention for its rich, confectionary flavor profile and approachable heat despite being bottled at barrel proof. The bottle label reads like a production manifest: corn varietal, mashbill percentages, distillation year, barrel entry proof, rickhouse identifier, floor numbers, and age statement. In an industry where "sourced" and "crafted" can obscure as much as they reveal, this level of detail is genuinely refreshing.

True Vertical Integration: Seed to Sip

The phrase "grain to glass" gets thrown around loosely in the spirits world. Heaven Hill backs it up with a documented supply chain that begins in the soil of Nelson County, Kentucky. The distillery partnered with Beck's Hybrids, a family-owned seed company out of Indiana that has been operating since 1937, to select a specific corn varietal—Beck's 6158 for the first edition, and Beck's 6225 for subsequent releases. This is not commodity corn from a broker. It is a deliberately chosen hybrid grown for its flavor potential.

Peterson Farms, a multi-generational farming family also based in Nelson County, cultivates that seed into the grain that enters the mashbill. The wheat component comes from the same local fields. From there, the grain moves to the Bernheim Distillery in Louisville for mashing, fermenting, and distilling before being barreled and transported to the Cox's Creek aging facility.

This level of vertical integration is exceedingly rare in American whiskey. Most producers purchase grain from commodity brokers and have little control over the agricultural side of production. Heaven Hill has deliberately shortened that chain, and the Grain-to-Glass series is their way of proving it. Proceeds from the line also support the Family Farms First Initiative, donating up to one hundred thousand dollars annually to Farm Rescue to assist family-owned farms in crisis. Every bottle of Heaven Hill Grain-to-Glass Wheated Bourbon supports that effort.

The Wheated Mashbill Explained

Most bourbon mashbills use rye as the secondary grain behind corn, which contributes spice, pepper, and a certain sharpness to the spirit. Wheated bourbons replace rye with wheat, and the result is a fundamentally different drinking experience. Wheat delivers softness, sweetness, and a rounder mouthfeel that makes barrel-proof expressions more approachable than their rye-heavy counterparts.

The Heaven Hill Grain-to-Glass Wheated Bourbon uses a mashbill of 52% corn, 35% wheat, and 13% malted barley. That wheat proportion is significant—it is considerably higher than many wheated bourbons on the market, which often sit in the 15-20% range. The generous wheat content gives this expression its signature pillowy texture and pronounced sweetness, while the corn provides the classic bourbon backbone and the malted barley contributes enzymatic conversion during fermentation along with subtle biscuit-like notes.

This particular mashbill places the bourbon squarely in the company of well-known wheated expressions like Maker's Mark and the Weller line, but the higher wheat content and barrel-proof bottling push it into territory that feels distinctly its own. Where some wheated bourbons can lean too far into soft sweetness and lose complexity, the 121-proof presentation here ensures there is enough structure and barrel influence to keep things interesting from the first sip to the last.

From Nelson County Fields to Cox's Creek Rickhouses

After the grain is harvested and delivered to the Bernheim Distillery in Louisville, it goes through a traditional sour mash process. The spirit comes off the still and enters new charred American oak barrels at a barrel entry proof of 107—a detail documented on every bottle. Lower entry proofs generally allow the distillate to interact more dynamically with the wood over time, extracting a richer range of flavors compared to spirits barreled at higher proofs.

The filled barrels then make their way to Heaven Hill's Cox's Creek aging facility, a massive complex of traditional rickhouses in Nelson County. For the inaugural 2024 release, the bourbon aged in rickhouse W3 on floors three through five. These upper-middle floors experience greater temperature fluctuation throughout the seasons, which accelerates the expansion and contraction of liquid into and out of the wood. The result is deeper color, more pronounced caramel and toffee development, and a fuller body compared to barrels aged on lower floors.

After six years of maturation—distilled in 2017, released mid-2024—the barrels were dumped and bottled at barrel proof without chill filtration. Skipping chill filtration preserves the fatty acids and long-chain esters that contribute to mouthfeel and flavor complexity. The bourbon may develop a slight haze when chilled or diluted, which is perfectly natural and a sign of quality craftsmanship.

Tasting Notes: Nose, Palate, and Finish

Pouring the Heaven Hill Grain-to-Glass Wheated Bourbon reveals a rich burnished copper color that speaks to its years in the upper rickhouse floors.

Nose

The aroma opens with a wave of coffee cake and brown sugar, layered with vanilla frosting and a gentle cinnamon-stick warmth. Let it breathe and you will find papaya, dark cherry, and a subtle dried fruitcake character that hints at holiday baking. There is a pleasant undercurrent of toasted oak and light creme brulee that grounds the sweeter notes and keeps the nose from feeling one-dimensional.

Palate

On the palate, this bourbon delivers exactly what the wheated mashbill promises: a rich, almost syrupy mouthfeel that coats every surface. The initial wave brings vanilla-drizzled cinnamon cake and brown butter, followed by a surprising canned fruit salad note—peach, pear, and cherry swimming in sweet syrup. White peppercorn and cinnamon spice emerge in the mid-palate, providing just enough counterpoint to keep the sweetness from becoming cloying. Oak influence is present but never domineering, offering structure rather than bitterness. Despite the 121 proof, the heat is remarkably well-integrated. This drinks like a bourbon ten to fifteen proof points lower than its actual strength.

Finish

The finish is long and satisfying, carrying forward the fruit salad character and layering in cinnamon spice, leather, and a gentle lingering vanilla. There is a dry oak quality that emerges toward the very end, balanced by a whisper of salted caramel. The heat builds gradually on the finish rather than hitting all at once, leaving a warm, pleasant glow that invites the next sip.

How to Enjoy This Barrel-Proof Wheated Bourbon

At 121 proof, the Heaven Hill Grain-to-Glass Wheated Bourbon is a versatile pour that rewards experimentation. Here are three approaches worth trying.

Neat, with patience. Pour two ounces into a Glencairn or tulip-shaped glass and let it rest for five to ten minutes. The non-chill filtered oils will bloom as the bourbon reaches room temperature, revealing the full spectrum of layered fruit, baking spice, and buttery richness.

With a few drops of water. A teaspoon or two of water can unlock aromas that the alcohol had been masking. With this expression, water amplifies the vanilla and fruit notes while softening the cinnamon spice, and it thickens the perceived mouthfeel—a common effect with non-chill filtered whiskeys.

Over a single large ice cube. Slow dilution allows the flavors to evolve over twenty minutes, and the cold temperature highlights caramel and toffee while muting heat. An excellent warm-weather approach for a bourbon this rich.

One thing to avoid: burying this bourbon in a heavily mixed cocktail. The nuance and provenance that make it special would be lost. Save it for moments when the whiskey itself is the star.

The Full Grain-to-Glass Lineup

The Grain-to-Glass series is released annually with multiple expressions. In 2024, Heaven Hill released a straight bourbon (traditional rye-grain mashbill), the wheated bourbon reviewed here, and a rye whiskey. Each uses the same locally sourced grain from Peterson Farms, but the mashbill, aging conditions, and rickhouse placement differ.

Comparing the three side by side is a masterclass in how secondary grains shape character. The straight bourbon leans spicier with black pepper and dried fruit. The rye turns up herbal and floral notes. The wheated bourbon goes full dessert mode with its vanilla, brown sugar, and cinnamon profile. All three share quality oak integration and barrel-proof intensity.

Heaven Hill has also introduced a Specialty Barrel Series within the line, featuring experiments like chinquapin oak barrels. This willingness to innovate within an already premium framework speaks to the distillery's long-term commitment to the program.

Where It Fits in the Wheated Bourbon Landscape

The wheated bourbon category has grown explosively over the past decade, driven by the fame of Pappy Van Winkle and the Weller line. Nearly every major distillery now offers at least one wheated expression. So where does the Heaven Hill Grain-to-Glass Wheated Bourbon fit?

In proof and intensity, it sits alongside barrel-proof wheated offerings like Maker's Mark Cask Strength and Weller Full Proof. But the transparency angle sets it apart. No other wheated bourbon tells you the corn seed varietal, the exact farm, and the specific rickhouse floors. That traceability is more commonly associated with single-estate wines or single-origin coffee than with bourbon.

At approximately one hundred dollars for a 700-milliliter bottle, it occupies a premium tier justified by both the liquid quality and the authentic story behind it. For collectors building a wheated bourbon shelf, this is an essential addition.

A Collector's and Enthusiast's Perspective

Limited annual releases with detailed provenance information hold their value well in the bourbon world, and the Grain-to-Glass series has all the hallmarks of a collectible line. Each year's release differs—corn varietals, rickhouse locations, proof points—making no two vintages identical. For enthusiasts who enjoy vertical tastings, this series offers a genuine opportunity to track evolution year over year.

The 2024 inaugural wheated bourbon carries particular significance as a first edition. Whether you open it now or shelve it alongside future releases, this bottle marks the beginning of what promises to be a compelling annual tradition from one of Kentucky's most storied distilleries.

Food Pairing Suggestions

The dessert-forward profile of Heaven Hill Grain-to-Glass Wheated Bourbon makes it a natural companion for rich dishes. Consider pairing it with pecan pie or bread pudding with caramel sauce—the bourbon's vanilla and brown sugar notes harmonize beautifully with caramelized sweetness.

For savory options, try it alongside smoked pork belly, barbecued brisket, or aged cheddar. The high proof cuts through fattiness while the wheat-driven softness keeps things balanced. Dark chocolate with at least 70% cacao is another excellent match, as the bitterness highlights the bourbon's sweeter notes by contrast.
