Castle & Key Wheated Cask Strength Bourbon 750ML

Castle & Key Wheated Cask Strength Bourbon 750ML is a 7-year-old, 108.2 proof (54.1% ABV) Kentucky bourbon built on an unconventional mashbill of white corn and white winter wheat. This expression earned a Double Platinum medal at the 2025 ASCOT Awards, validating a grain-forward approach that prioritizes mellow sweetness and yeast character over heavy oak influence.Quick Facts: ABV: 54.1% (108.2 proof)  |  Origin: Frankfort, Kentucky  |  Age: 7 Years  |  Distillery: Castle & Key (Historic Old Taylor Distillery)Production & HeritageCastle & Key operates out of the restored Old Taylor Distillery in Frankfort, Kentucky — a landmark originally built by Colonel Edmund Haynes Taylor Jr. in 1887. The distillery’s wheated bourbon uses a mashbill of 73% white corn, 10% white winter wheat, and 17% malted barley, a notable departure from convention on multiple fronts: white corn and white wheat replace the standard yellow corn and red winter wheat found in most Kentucky bourbons, and the malted barley percentage sits well above the industry-typical 10%. The production process relies on sweet mash fermentation conducted at low temperatures, with a low barrel entry proof designed to let the grain and yeast character develop more fully across seven years of maturation. The result is bottled at cask strength without chill filtration.Tasting NotesAroma: Oatmeal raisin cookie and vanilla frosting lead, followed by baked peach and candied pear. Underneath, softer layers of orange peel, lilac, and gentle cinnamon emerge with time in the glass.Taste: The entry is remarkably creamy for its proof — almost silky — opening into almond pastry, butterscotch, and macaroon. Mid-palate, baking chocolate and dried cranberry surface alongside clove and subtle floral tones. The texture belies the 108.2 proof, carrying weight without aggression.Finish: Long and warming, anchored by raw brown sugar and roasted walnut. As it fades, leather and French toast linger, leaving a pleasant sweetness that persists well after the sip.How to Drink Castle & Key Wheated Cask StrengthAt 108.2 proof, this bourbon rewards patience — pour it neat and let it breathe for several minutes, or add a few drops of water to open up the pastry and stone fruit notes without diminishing structure. The cask strength also makes it a powerhouse in cocktails. An Old Fashioned benefits from the butterscotch and brown sugar depth, standing up to bitters and dilution with ease. A Boulevardier pairs the bourbon’s baking chocolate and clove against sweet vermouth and Campari for a rich, layered drink. A Paper Plane highlights the lighter citrus and floral aromatics that might otherwise stay in the background.Best For

It is distilled and aged at Castle & Key Distillery in Frankfort, Kentucky, which operates out of the historic Old Taylor Distillery originally established in 1887.What foods pair well with Castle & Key Wheated Cask Strength?

It positions as a premium craft bourbon within the wheated cask-strength category, competing against widely distributed labels like Maker’s Mark Cask Strength and the Weller line. The unconventional white grain mashbill, seven years of age, and Double Platinum ASCOT recognition place it firmly in the serious-sipping tier, offering genuine distinctiveness rather than incremental variation.Why Castle & Key Wheated Cask Strength?What sets this bourbon apart from the crowded wheated field is the deliberate use of white corn and white winter wheat — grains chosen specifically for their mellow character, allowing yeast-driven flavors to assert themselves in ways that yellow corn and red wheat typically overpower. The 17% malted barley, nearly double the Kentucky standard, adds a biscuity richness that anchors the pastry and confectionery notes throughout the palate. Seven years of aging at a low barrel entry proof builds complexity without the tannic bite that plagues many cask-strength releases of similar age. The Double Platinum from the 2025 ASCOT Awards confirms that this is not simply a novel experiment — it is a bourbon that performs at the highest competitive level while charting its own course.
