Some whiskies stand alone. These two speak to each other.
The 12 Year Old and the 21 Year Old Cask Strength 2025 Editions are not just releases from the same distillery, they are reflections across time. Two whiskies born of the same unpeated Islay spirit, shaped differently by age, oak, and the patience of the sea air.
Together, they tell a story of strength: one spirited and raw, the other refined and poise.
The Mirror of Time: 12 - 21
There's powerful symbolism in these numbers. Not only are they numerically satisfying in their reversal of each other, but 12 becomes 21 with time and stillness. Within 21, you can still find 12. Its energy, its heartbeat, its unmistakable Islay character.
This is more than symmetry. it's a mirror held up to the passage of years, showing how time reshapes the same spirit into new forms.
- 12 Year Old Cask Strength is spirited, raw, elemental. Strength at its most expressive.
- 21 Year Old Cask Strength is composed, mature, layered. Strength that has settled into wisdom.
Together, they form a dialogue. A conversation across years, revealing how age transforms not only whisky, but perspective.
12 Year Old Cask Strength 2025 Edition: Quiet Power
The 12 Year Old has always been the foundation of Bunnahabhain: unpeated, richly sherried, and unmistakably coastal. At cask strength, it's whisky in its purest from. Full of energy, depth, and character.
The 2025 Cask Strength Edition refines that energy with focus and clarity. Matured in a thoughtful mix of predominantly second fill Oloroso casks, with first fill and refill casks layered in, it offers balance without compromise.
At 56.4% ABV, the whisky speaks with authority:
- Nose: Dried apricot, toasted hazelnuts, and soft maritime brine.
- Palate: Golden sultanas, malted barley, and gentle spice.
- Finish: Long, savoury, and layered with oak, spice, and sea spray.
This is strength with restraint. A whisky that rewards patience in the glass, evolving sip by sip.

21 Year Old Cask Strength 2025 Edition: PX Influence, Coastal Soul
If our 12 Year Old is the heartbeat, the 21 Year Old is the deep breath. The same spirit, given decades to evolve.
Matured in ex-Oloroso casks before a 21-month finish in 21 hand-selected Pedro Ximénez casks, it is a meeting of crafts: the rich, syrupy sweetness of Jerez and the nutty, saline soul of Bunnahabhain's Islay spirit.
At 53.1% ABV, it trades intensity for refinement. A small 0.5% difference from the 2024 release, but one that transforms the texture and tone.
- Nose: Rich dried fruits, treacle toffee, walnut, and leather.
- Palate: PX-soaked raisins, chocolate-dipped cherries, espresso, roasted nuts, and warming spice.
- Finish: Long and warming, with prunes, dark chocolate, and a final whisper of sea salt.
This is strength with poise. A whisky that speaks softly but carries depth, composure, and rarity.
A Conversation Across Flavour
Where the 12 Year Old Cask Strength is bright and energetic, the 21 Year Old Cask Strength is deep and composed. Both carry unmistakable Bunnahabhain DNA, but their voices diverge with age.
Together, they illustrate how time shifts flavour, turning brightness into richness, energy into poise.
The Cask Strength Series
Cask Strength at Bunnahabhain has never been about raw power. It's about integrity, bottling whisky exactly as it was meant to be, with nothing added, nothing taken away. The series celebrates this philosophy across time; the 12 Year Old is our foundation amplified and the 21 Year Old is our prestige perfected. Together, they invite drinkers into a deeper conversation about whisky, age, and the quiet strength of patience.
Unfiltered. Uncompromised. Unmistakably Bunnahabhain.
