Some whiskies shout. Ours never has to.
The 12 Year Old Cask Strength series has always been an expression of the purest single malt - whisky drawn straight from the cask, unfiltered and undiluted. But the 2025 Edition goes further. It doesn't just deliver strength - it offers clarity and poise. A deeper expression of what makes Bunnahabhain so distinct.
This is quiet power built on the edge of Islay.
A Tradition Born in Warehouse 9
There's a moment every visitor remembers.
Deep in the coastal stillness of Warehouse 9, away from the hum of the stillhouse, guests are invited to take their first sip of Bunnahabhain spirit drawn straight from cask. No water, no chill-filtration and no interventions; just spirit, wood and time united by the salt air of the Sound.
The moment inspired the very first 12 Year Old Cask Strength release in 2021. Since then, each edition has offered drinkers a rare perspective our iconic core 12 Year Old amplified in strength and in structure, but never noise.
"There's a misconception about cask strength that it always means bigger, bolder, louder. At Bunnahabhain, it's not about power for power's sake. It's about presenting our spirit in its most natural form."
Julieann Fernandez, Master Blender
The 2025 Edition: Precision Over Intensity
This year's 12 Year Old Cask Strength is the most refined edition yet. Drawn from a thoughtful combination of predominantly second fill Oloroso sherry casks, with touches of first fill and refill casks for subtle flavour layering, the 2025 release brings complexity without compromise.
All casks were matured at Bunnahabhain's coastal warehouses, where cool, salt-laden air slows the maturation process, building structure and nuance over time. The result? A whisky that leads with clarity, not confrontation.
At 56.4% ABV, its bottled exactly as Julieann intended - natural colour, non-chill filtered, unaltered.
Tasting the 2025 Edition
This is not a sherry bomb. It's something quieter - more cerebral. A single malt that speaks in layers.
On the Nose: Dried apricot, soft brine, and toasted hazelnuts.
On the Palate: Golden sultanas, malted barley, and gentle spice unfurl over a backbone of light tobacco and sea spray.
The Finish: Long and savoury notes of delicate oak, drying spice and a final whisper of salt.
"I wanted to create something that felt deliberate", says Julieann. "The second fill casks allow the spirit to shine. You get all the elegance of the sherry influence, but the coastal character isn't lost. It's layered, but not loud."

A Different Kind of Strength
Cask strength doesn't always mean impact. At Bunnahabhain, it means integrity.
"The character of Bunnahabhain is built by time and tide," says Andrew Brown, Distillery Manager. "We don't rush anything. Every cask in this release matured here, on site with the sea in the air and patience in the wood."
That patience pays off.
Where previous editions leaned into darker fruit and deeper spice, the 2025 edition feels lighter - more mineral, more restrained. It speaks to the evolving vision of our blending team, and the quiet confidence of our spirit.

The Flavour, Visualised
To bring the character of the 2025 release to life, we compared it to the 2023 edition of 12 Year Old Cask Strength.
The 2025 edition is more structured, less overtly sweet, and notably more coastal than its predecessors. A return to the roots of Islay's gentler side.
Final Thoughts
This isn't a whisky engineered to impress with weight. It's a whisky built with intention.
From the sea-kissed casks of Warehouse 9 to the glass in your hand, 12 Year Old Cask Strength 2025 Edition is a reminder of what happens when you let the spirit do the talking.
Unfiltered. Uncompromised. Unmistakably Bunnahabhain.
FAQs: 12 Year Old Cask Strength 2025 Edition
1. What does "cask strength" actually mean?
Cask strength whisky is bottled at the natural ABV it reaches when maturing in cask with no dilution or chill-filtration. It's as close as you can get to tasting whisky straight from the barrel, delivering full flavour, unfiltered texture, and complete integrity.
2. How is the 2025 edition different from previous 12 Year Old Cask Strength releases?
This edition focuses on precision rather than power. Julieann selected a careful mix of second fill, first fill and refill Oloroso casks, allowing the spirit's natural character to shine through. It's more structured, more coastal, and slightly less sherried than previous releases - elegant rather than intense.
3. What kind of flavours can I expect from 12 Year Old Cask Strength 2025 Edition?
Expect dried apricot, hazelnut, gentle maritime brine, light spice, and a soft savoury finish. The sherry influence is subtle, giving space for malt and coastal notes to take centre stage.
4. Is 12 Year Old Cask Strength peated?
No. Like our classic 12 Year Old, this release is unpeated, allowing the natural richness of the sherry casks and the coastal maturation to define its character.
5. Can I add water to cask strength whisky?
Absolutely. Many enthusiasts enjoy experimenting with a few drops of water to open up the aromas and alter the structure. But we bottle it this way so you have the freedom to experience it exactly how you prefer - neat, with water, or even over time in the glass.
