This limited release earned a Double Gold medal at the New York World Wine & Spirits Competition and a Silver at the International Wine & Spirit Competition, signaling the kind of depth and complexity that places it among the most distinctive American whiskeys currently available.Quick Facts: ABV: 51.9% (103.8 Proof)  |  Origin: Kentucky, USA  |  15 Year Age Statement  |  Distillery: Rabbit Hole DistilleryProduction & HeritageRabbit Hole Distillery, founded in Louisville, Kentucky by Kaveh Zamanian, built its reputation on unconventional grain bills and inventive finishing techniques. This Founder’s Collection expression begins as a 15-year-old Kentucky Straight Bourbon aged in American oak barrels, then undergoes an additional year of finishing in barrels made from Japanese Mizunara oak — a notoriously rare and difficult wood to cooper. The Mizunara oak is sourced from trees that take between 200 and 500 years to reach maturity, with the barrels crafted by the Ariake Sangyo cooperage in Japan, one of the few facilities in the world with the expertise to shape this porous, delicate wood into functional aging vessels.Tasting NotesAroma: The nose opens with ripe banana and pear, then shifts into cherry and a bright mint lift. Beneath those fruit tones, nutmeg, walnut, leather, honey, and orange develop in layers as the bourbon breathes.Taste: On entry, rich tobacco and seasoned oak dominate, giving way at the mid-palate to custard, banana, and warm cinnamon. The Mizunara influence emerges as the bourbon opens further, introducing floral rose and honey tones that weave through the heavier spice and wood notes.Finish: Long and textured, with buttered oak, clove, and caramelized sugar lingering well past the swallow. A chocolate-cherry note fades slowly alongside dried tropical fruit, leaving a warm, spice-driven close.How to Drink Mizunara 15 YearAt 103.8 proof, this bourbon rewards patient sipping — try it neat first to appreciate the full arc from tobacco and custard through the floral Mizunara character, then add a few drops of water to unlock additional sweetness and soften the oak. For cocktails, its bold structure holds up remarkably well in three classic builds: an Old Fashioned, where the cherry and caramel notes shine against bitters and sugar; a Boulevardier, where the tobacco and oak stand up to Campari’s bitterness; and a Whiskey Sour, where the bourbon’s fruit-forward aromatics amplify the citrus element.Best For

Frequently Asked QuestionsWhat does Mizunara 15 Year taste like? The dominant profile centers on tobacco, custard, and warm baking spice layered over ripe banana and cherry, with a distinctive floral quality and a long chocolate-cherry finish imparted by the Mizunara oak finishing.How does Mizunara 15 Year compare to Michter’s 10 Year? Both deliver mature, oak-driven bourbon profiles without becoming overpoweringly tannic, but the Rabbit Hole distinguishes itself with the floral, sandalwood-like character of Mizunara oak and an additional five years of age. Michter’s 10 Year leans more classically into caramel and butterscotch, while the Mizunara finish here introduces an exotic spice and rose element rarely found in American whiskey.Is Mizunara 15 Year good for sipping neat? Absolutely — this is primarily a sipping bourbon, with the complexity and proof to reward undiluted tasting, though a small addition of water can open up the floral and fruit notes further.Where is Mizunara 15 Year made? It is produced at Rabbit Hole Distillery in Louisville, Kentucky, using bourbon aged in American oak before finishing in Japanese Mizunara oak barrels crafted by the Ariake Sangyo cooperage in Japan.What foods pair well with Mizunara 15 Year? Dark chocolate truffles complement the chocolate-cherry finish; grilled wagyu or smoked brisket matches the tobacco and oak backbone; roasted pear or apple tart echoes the fruit aromatics; aged Gouda provides a caramel counterpoint to the spice; and spiced pecans mirror the cinnamon and nutmeg notes.What sizes does Mizunara 15 Year come in? The standard release is a 750ml bottle, which is the primary format available for this Founder’s Collection expression.Is Mizunara 15 Year worth the price? This expression positions firmly in the ultra-premium tier, justified by its 15-year age statement, the rarity and cost of genuine Mizunara oak barrels, and its Double Gold recognition — placing it among the most distinctive limited-release bourbons in its class.Why Mizunara 15 Year?The defining differentiator here is the Mizunara oak finish — Mizunara trees require centuries to mature, and the wood itself is so porous and prone to leaking that only a handful of cooperages worldwide can successfully build barrels from it. That scarcity translates directly into the glass: the floral, incense-like character this oak imparts is genuinely unlike any other finishing wood used in bourbon production. Backed by a Double Gold medal and built on a fully mature 15-year base spirit, this Founder’s Collection release delivers the kind of layered, evolving complexity that stands apart from conventional long-aged bourbons and gives collectors a legitimate reason to seek it out.
