Heaven Hill Double Mash 9 Year Bourbon 750ML

Heaven Hill Double Mash 9 Year Bourbon 750ML is a 100-proof (50% ABV), 9-year-old Kentucky straight bourbon in a 750ml bottle that combines two distinct mashbills into a single expression. Produced by one of America’s largest independent, family-owned distilleries, this bottling uses the “double mash” approach to layer different grain profiles, yielding a bourbon with unusual depth for its age statement.

Production & Heritage
Heaven Hill Distillery was founded in 1935 in Bardstown, Kentucky, and remains owned by the Shapira family to this day — making it one of the few major American distilleries still under independent family control. The distillery operates a traditional column still paired with a copper doubler, a setup responsible for producing bourbon across its extensive portfolio. The Double Mash 9 Year expression draws from two separate mashbills, each distilled and aged individually in new charred American oak barrels before being married together. This blending of two grain recipes — each bringing different proportions of corn, rye, and malted barley — creates a complexity that a single-mashbill bourbon of the same age would not typically achieve. All aging occurs in Kentucky’s climate-variable rickhouses, where nine years of seasonal temperature swings drive deep interaction between spirit and wood.
Tasting Notes
Aroma: Rich caramel and toasted vanilla lead, followed by darker notes of dried cherry, baking spice, and seasoned oak. A faint whiff of roasted grain and leather emerges as the bourbon opens up in the glass.
Taste: The entry is full and slightly sweet, with brown sugar and corn sweetness giving way to a mid-palate surge of cinnamon, rye spice, and cocoa. The two mashbills make themselves known here — one contributing grain-forward sweetness, the other a drier, spicier backbone. At 100 proof, the mouthfeel carries weight without turning hot.
Finish: Medium-long, with toasted oak, dark toffee, and a lingering pepper-and-char dryness. A subtle nuttiness appears at the tail end, leaving a warm, satisfying close.
How to Drink Double Mash 9 Year
At 100 proof, this bourbon rewards neat sipping or with a few drops of water, which can open up the sweeter grain notes beneath the oak. A single large ice cube also works well, tempering the proof without diluting the layered complexity. For cocktails, the 9-year depth and bottled-in-bond-strength proof hold up admirably: an Old Fashioned benefits from the caramel and spice balance; a Manhattan gains structure from the oak tannins and rye-spice character; and a Boulevardier pairs naturally with the darker, cocoa-tinged notes in the finish.

Frequently Asked Questions
What does Double Mash 9 Year taste like? It delivers rich caramel, brown sugar, and toasted vanilla up front, followed by rye spice, cocoa, and seasoned oak, finishing with toffee and black pepper. The dual-mashbill construction gives it more grain complexity than a typical single-recipe 9-year bourbon.
How does Double Mash 9 Year compare to Knob Creek 9 Year? Both are 100-proof, 9-year-old Kentucky bourbons, but Double Mash 9 Year uses two blended mashbills while Knob Creek relies on a single high-corn recipe from Beam Suntory’s Jim Beam Distillery. The result is that Double Mash tends toward broader grain complexity, while Knob Creek leans into robust, straightforward oak and caramel intensity.
Is Double Mash 9 Year good for sipping neat? Yes — the 100-proof strength is assertive but not overwhelming, and the nine years of barrel aging have smoothed out harshness while adding layers of oak, spice, and dried fruit that reward slow, undiluted sipping.
Where is Double Mash 9 Year made? It is produced by Heaven Hill Distillery in Bardstown, Kentucky, which has been the Shapira family’s home base for bourbon production since 1935. Bardstown sits in the heart of Kentucky’s bourbon-producing region, often called the “Bourbon Capital of the World.”
What foods pair well with Double Mash 9 Year? Smoked brisket or pulled pork pairs well because the bourbon’s oak and char notes mirror the smokiness; pecan pie complements its caramel and nutty finish; dark chocolate matches the cocoa undertones; aged cheddar or Gruyère contrasts the sweetness with savory depth; and crème brûlée echoes the toasted vanilla character.
What sizes does Double Mash 9 Year come in? The standard release is a 750ml bottle. Availability in other sizes may vary by market.
Is Double Mash 9 Year worth the price? It positions as a premium-tier bourbon within Heaven Hill’s lineup, sitting above their entry-level offerings but below allocated single-barrel or limited-edition releases. The combination of a 9-year age statement, 100-proof strength, and the distinctive double-mashbill technique represents strong value relative to other aged, full-proof Kentucky bourbons in the same bracket.
Why Double Mash 9 Year?
The defining feature here is the dual-mashbill construction — a technique that relatively few major distilleries employ for a standard release at this age and proof. Heaven Hill’s scale as one of the largest bourbon producers in the world means they have the inventory and the range of mashbills to execute this blend with consistency. Nine years in new charred oak at Kentucky’s temperature extremes yields a maturity that many bourbons in this price tier cannot match, and the 100-proof bottling strength ensures nothing is lost to excessive dilution. For drinkers who appreciate the nuance that different grain recipes bring and want an age-stated bourbon that performs equally well neat or in a robust cocktail, this expression delivers on a clear, specific promise.
