I.W. Harper Cabernet Cask Reserve Bourbon 750ML

I.W. Harper Cabernet Cask Reserve Bourbon 750ML is a 90-proof Kentucky straight bourbon finished in California Cabernet Sauvignon wine casks, bottled at 750ml. This dual-maturation approach—four years in new charred American oak followed by a secondary rest in Cabernet casks—bridges the gap between traditional bourbon character and layered dark-fruit complexity in a way few finished bourbons attempt.

Quick Facts: ABV: 45% (90 Proof)  |  Origin: Kentucky, USA  |  Style: Wine Cask-Finished Bourbon  |  Distillery: New Bernheim (Bottled at Stitzel-Weller)

Production & Heritage

I.W. Harper is a historic American bourbon brand now owned by Diageo. The Cabernet Cask Reserve expression is distilled at the New Bernheim Distillery (a Heaven Hill facility) in Louisville, Kentucky, then bottled at the storied Stitzel-Weller Distillery, also in Louisville. The mashbill runs 73% corn, 18% rye, and 9% malted barley—a rye-forward grain recipe that provides structure before the wine-cask influence takes hold. After its initial four-year maturation in new charred American oak barrels, the bourbon is transferred into casks that previously held California Cabernet Sauvignon, allowing the residual wine tannins and fruit sugars to integrate with the base spirit. The result is a bourbon that retains its grain-driven backbone while picking up a distinctly vinous dimension.

Tasting Notes

Aroma: Caramel and brown sugar lead the nose, followed closely by dark cherry and sweet raisin. A second pass reveals black raspberry, vanilla, and a subtle crème brûlée sweetness layered beneath a faint cornhusk note.

Taste: The entry is smooth and gently sweet, with vanilla and light caramel arriving first. At mid-palate, the Cabernet influence asserts itself—dark fruit and a thread of berry tartness emerge alongside toasted oak. The rye component surfaces toward the peak, adding a measured spice that keeps the sweetness in check.

Finish: Medium in length with a smoky, oak-driven fade and lingering hints of dark fruit. The close is clean and balanced, with no harsh tannic grip from the wine cask.

How to Drink Harper Cabernet Cask Reserve

Neat or with a single large ice cube is the most revealing serve, allowing the wine-cask nuances to unfold gradually as the bourbon opens up. A few drops of water will amplify the dark cherry and berry notes without diluting the oak structure.

• Manhattan: The dark-fruit undertones mirror the sweet vermouth, creating a seamless, berry-accented variation.
• Boulevardier: Cabernet-cask tannins stand up to the bitterness of Campari while the fruit notes amplify the cocktail's complexity.
• Old Fashioned: The inherent sweetness reduces the need for added sugar, letting the wine-cask character shine through with just a dash of bitters.

Why Harper Cabernet Cask Reserve?

The Cabernet Sauvignon cask finish remains relatively uncommon in bourbon, where port and sherry casks dominate the wine-finished category. That distinction alone gives this expression a different flavor lane—drier and more tannic than port-finished alternatives, with a dark-fruit profile that integrates cleanly with the 73% corn, 18% rye mashbill. The combination of New Bernheim distillation and Stitzel-Weller bottling ties the liquid to two of Kentucky's most recognized bourbon facilities. For drinkers who find port-finished bourbons overly sweet, this Cabernet-cask bottling provides a structured, balanced alternative that still delivers the richness cask finishing is meant to achieve.
