Production & Heritage

Rabbit Hole Distillery was founded in Louisville, Kentucky, by Kaveh Zamanian, a psychologist-turned-distiller whose brand launched in 2012 before its purpose-built distillery opened on Jefferson Street in 2018. The operation is now part of the Pernod Ricard portfolio. Boxer Grail is distilled through a handcrafted Vendome copper pot still using a high-rye mashbill of 95% rye and 5% malted barley, then proofed with Kentucky limestone water. What distinguishes this expression from most rye whiskeys is its barrel treatment: each barrel is toasted over a wood fire before being charred, an additional step that caramelizes wood sugars more gradually than standard charring alone. After eight years of maturation in these specially prepared new American oak barrels, the whiskey emerges with a depth of sweetness and oak integration that the standard charring process cannot replicate on its own.

Tasting Notes

Aroma: The nose opens with powdered sugar and glazed donut sweetness before moving into candied nuts and vanilla custard. Dark fruit emerges underneath — cherry and blackberry — creating a layered, dessert-like bouquet that belies the whiskey's barrel proof strength.

Taste: The entry is rich and full-bodied, immediately coating the palate with grape jelly and allspice warmth. At mid-palate, the rye grain's peppery backbone asserts itself alongside the barrel's contribution. With a few drops of water, the profile expands into semi-sweet chocolate, licorice, honey-coated almonds, and toasted oak, revealing additional dimensions without sacrificing intensity.

Finish: Long and well-structured, the finish is anchored by balanced oak that never turns astringent despite the eight-year maturation. Raspberry tart, baking spice, maple syrup, and tiramisu linger in succession, rewarding patient sipping.

How to Drink Boxer Grail

At 103.8 proof, Boxer Grail is built for neat sipping — pour it, let it breathe for a few minutes, and add water incrementally to unlock the chocolate and licorice notes hiding beneath the proof. It also holds its own in spirit-forward cocktails. A Sazerac benefits from the grape jelly and allspice character, which pair naturally with absinthe and Peychaud's bitters. In a Manhattan, the dark fruit and vanilla custard notes amplify sweet vermouth without being overwhelmed. An Old Fashioned built with this rye lets the baking spice and maple syrup qualities shine through a simple sugar and bitters framework.

Frequently Asked Questions

What does Boxer Grail taste like? Boxer Grail delivers a rich, spice-forward palate dominated by grape jelly, allspice, and baking spice, with a long finish of raspberry tart, maple syrup, and tiramisu. Adding water reveals semi-sweet chocolate, licorice, and honey-coated almond notes beneath the barrel-proof intensity.

How does Boxer Grail compare to Redemption 10 Year Rye? Both are oak-forward aged rye whiskeys, but Boxer Grail's wood-fired barrel toasting process produces a sweeter, more dessert-driven profile with pronounced dark fruit and pastry notes. Redemption 10 Year Rye tends to lean into drier, more tannic oak character from its additional two years of maturation in conventionally prepared barrels.

Is Boxer Grail good for sipping neat? At 51.9% ABV, Boxer Grail is an excellent neat sipper for experienced rye drinkers, though a few drops of water open up significant secondary flavors like chocolate and licorice that may otherwise stay hidden behind the proof.

Where is Boxer Grail made? Boxer Grail is produced at Rabbit Hole Distillery in Louisville, Kentucky, where it is distilled through a Vendome copper still and proofed with local Kentucky limestone water before aging on-site.

What foods pair well with Boxer Grail? Dark chocolate truffles complement the whiskey's semi-sweet chocolate and vanilla custard notes. Smoked brisket matches its allspice warmth and oak character. Blue cheese plays off the grape jelly and dark fruit sweetness. Pecan pie mirrors the candied nut and maple syrup qualities. Charcuterie with fig jam echoes the berry-forward finish.

What sizes does Boxer Grail come in? Boxer Grail is available in the standard 750ml bottle size as part of the Founder's Collection limited releases.

Is Boxer Grail worth the price? Boxer Grail positions as a premium, limited-release rye whiskey, and its eight-year age statement, barrel-proof bottling, and specialized wood-fired barrel toasting process place it in the upper tier of American rye. For drinkers who value age-stated, cask-strength rye with distinctive barrel treatment, it represents a strong value within its competitive set.

Why Boxer Grail?

The wood-fired barrel toasting process is the defining feature here — it is an uncommon, labor-intensive step that most distilleries skip in favor of standard machine-charring. That extended toasting caramelizes barrel sugars differently, producing the dessert-like sweetness and dark fruit depth that set Boxer Grail apart from other aged rye whiskeys. The 95% rye mashbill at barrel proof ensures the grain itself is never overshadowed, delivering genuine rye spice alongside the oak influence. For collectors and serious rye drinkers, this Founder's Collection release demonstrates what happens when high-quality distillate meets patient aging in thoughtfully prepared wood.
