Where Jerez meets Islay, something remarkable happens.

The 21 Year Old Cask Strength was first matured in Oloroso sherry casks. A hallmark of depth, nuttiness, and structure. But its defining character comes from its long 21-month finish in 21 hand-selected Pedro Ximénez casks, sourced from the sherry-making region of Jerez.

Here syrupy richness meets salt air. The chalky soils of Jerez bring sweetness and weight, while the winds of Bunnahabhain Bay impart freshness and quiet strength. Together, they create a whisky that is both luscious and balanced, sweet and salty, indulgent and unmistakably coastal.

"This release feels like a conversation between two places", says Julieann Fernandez, Master Blender. "The richness of PX is unmistakable, but it never overwhelms the spirit. You still get that nutty, saline Bunnahabhain character running through it. Like the tide cutting through the sweetness."

The 21 Year Old Cask Strength isn't just about cask influence; it's about restraint. Our robust, oily spirit can stand up to long maturation, but it also demands balance. That's why the 21-month PX finish is so deliberate: long enough to infuse depth and richness, but never so long that it drowns the coastal soul of Bunnahabhain.

Every decision reflects patience and craft: the choice of cask, the length of finishing, the precise ABV. Nothing rushed. Nothing compromised. Just a whisky that carries 21 years of time with effortless confidence.

At first glance, a 0.5% difference in ABV between the 2024 and 2025 editions may seem negligible. But in the glass, it transforms the whisky.

The 2024 edition was bold and powerful. Full of darker fruits, heavier spice, and intensity that filled the palate. The 2025 edition, bottled at 53.1%, tells a subtler story. That slight drop opens up a silkier texture, allowing candied orange, raisins, and delicate floral notes to shine. The spice is gentler. The finish smoother. The balance more composed.

"Cask strength doesn't always have to be about power," Julieann explains. "Sometimes, it's about poise. The 2025 release show how small changes can bring a whisky into perfect focus."

This year's edition is indulgent yet precise - layers of richness carried with elegance.

• Nose: Rich dried fruit, treacle toffee, and brown sugar lead, with hints of walnut, leather and a whisper of coastal clarity.
• Palate: Sweet PX-soaked raisins and chocolate-dipped cherries lead, followed by roasted nuts, espresso, spiced oak, and warming cinnamon.
• Finish: Long and warming, with dark chocolate, prunes, and a touch of sea salt.

Together with the 2024 release, the 2025 edition showcases two sides of cask strength: one defined by boldness, the other by refinement.

Every bottle of 21 Year Old Cask Strength is natural in colour, non-chill filtered, and bottled at cask strength. Only 2,568 bottles exist worldwide.

This scarcity makes it more than just a whisky to enjoy - it's a whisky to treasure. A testament to the craft of sherry-making in Jerez, the coastal soul of Bunnahabhain, and the patience of 21 years.

As Andrew Brown, Distillery Manager, puts it: "This is whisky shaped by place - by the sea at Bunnahabhain, by the soils of Jerez, and by the quiet patience of time. It's as much a story as it is a spirit."
