New Label: Glenmorangie Ozark Cask Strength 15 Years Old Limited Edition

A New 15 Year Cask Strength Expression

Glenmorangie has announced a new limited edition: the 15 Years Old Ozark Cask Strength, bottled at 48.5% ABV. The whisky has been matured entirely in slow grown American oak sourced from the Ozark Plateau in Missouri, a region the distillery has worked with for decades to craft casks with specific characteristics.

The announcement arrives via a TTB (Alcohol and Tobacco Tax and Trade Bureau) filing dated September 2026, signaling the imminent release of this bottling to the US market. Glenmorangie has not yet made a public statement about the release or confirmed availability in other markets.

The Ozark Oak Program

Glenmorangie's relationship with Ozark oak spans multiple expressions across its range. The distillery sources its wood from the Ozark Mountains, choosing trees with a specific growth pattern: eight to twelve growth rings per inch. This slow growth, driven by the region's dry climate and nutrient poor soil, creates wood with a higher density of vanillin and other compounds that deepen maturation.

Once felled, the oak is air dried for two years. This extended seasoning breaks down tannins, reducing astringency and preparing the wood for intensive maturation. Glenmorangie then shapes this oak into bespoke casks with exacting specifications before shipping them to Scotland for bourbon seasoning and eventual filling.

The Ozark wood has appeared in several of Glenmorangie's core range and limited editions over the years, most notably in the Ealanta (aged 19 years in virgin Ozark oak) and The Cadboll Estate (a 15 year old aged 43% ABV in first fill American oak bourbon casks). The distillery's Original expression, the 10 year foundation of the range, also matures in Ozark sourced casks.

Cask Strength Maturation and Flavor Profile

The 48.5% ABV distinguishes this expression from Glenmorangie's standard bottled at 46% limited editions and the lower strength Cadboll Estate. At this proof, the whisky retains a higher concentration of volatile compounds from the wood, creating a heavier mouthfeel and more pronounced oak integration than lower alcohol expressions of the same age.

The intensive American oak aging at cask strength results in a robust single malt shaped by the vanillin, tannin, and vanilla notes characteristic of Ozark wood. The lengthy air drying process employed by Glenmorangie ensures these compounds integrate cleanly rather than introducing excessive astringency, a balance that becomes more critical when bottling at cask strength.

Within Glenmorangie's Lineup on Spiritory

The Ozark Cask Strength joins several other Glenmorangie limited editions already available on Spiritory. The distillery has sustained a steady release cadence: the Harrison Ford Limited Edition launched in May 2026 as a bourbon and red wine cask blend at 46.5% ABV, while the 23 Years Old Year of The Horse, released for Lunar New Year 2026, offered added age in a commemorative format. The distillery also has the 25 Years Old The Altus on the platform, released in August 2025.

A significantly older expression, the 50 Years Old Limited Edition, is scheduled to arrive on Spiritory on September 15, 2026, offering collectors an extended age option from the same distillery.

The Glenmorangie 15 Years Old Ozark Cask Strength Limited Edition will be available on Spiritory. Pricing and an exact release date have not yet been confirmed. The TTB filing indicates the release is imminent, though specific details including bottle count and retail pricing remain undisclosed by the distillery.

Frequently Asked Questions

How does the Ozark Cask Strength differ from Glenmorangie's Cadboll Estate 15 year old?

Both are 15 year old expressions matured in American oak from the Ozark Plateau, but the Ozark Cask Strength is bottled at 48.5% ABV, whereas the Cadboll Estate releases at 43% ABV. The higher proof in the Ozark Cask Strength intensifies oak integration and creates a heavier mouthfeel. Additionally, the Cadboll Estate uses only barley grown on Glenmorangie's own estate, a distinction that does not apply to the Ozark Cask Strength.

Why does Glenmorangie source oak from the Ozark Plateau specifically?

The Ozark region's dry climate and nutrient poor soil produce slow growing trees with dense wood containing higher concentrations of vanillin and other maturation driving compounds. Glenmorangie selects trees with eight to twelve growth rings per inch and air dries the oak for two years to break down tannins, producing wood that delivers vanilla and depth without excessive harshness at cask strength.

Is the Ozark Cask Strength a one time release or part of an ongoing series?

Glenmorangie has not disclosed whether this will be a one off limited edition or recurring release. The TTB filing confirms it exists, but the distillery has not yet released public details about production volume or planned future bottlings in this format.

When can I expect to purchase the Ozark Cask Strength?

The TTB filing from September 2026 indicates an imminent release, but the distillery has not announced a specific date or pricing. The bottle will be available on Spiritory once it launches; monitor the platform for updates on release timing and details.
