New Scottish spirits brand submerges casks in Loch Ness

Named after the Gaelic word for 'deep', Domhayn was born from an unexpected moment of inspiration. Founder James Patterson was watching wild swimmers take a celebratory dram after a dook in Loch Ness when the idea struck.
Fast forward 20 years of research and - for the first time in history - a spirit-filled wooden cask has been plunged to the depths of Loch Ness, some 214 meters (702 feet) beneath the surface.
This process is said to "enhance and smooth spirits, creating unique flavour profiles compared to those achieved by traditional maturation".

James Patterson, Domhayn's founder, said: "This is about pushing the boundaries of how we understand spirit maturation.
"We know the environment a cask matures in has a huge impact, but no one has explored the application of pressure like this before. The results have been astounding."
Domhayn's inaugural release comes from cask DLNABK, which was submerged in Loch Ness on Valentine's Day 2025. There are only six bottles of the 2010 single malt barley spirit, bottled at natural strength 55.5% ABV.
Mr Patterson added: "When we retrieved the cask, the difference was undeniable.
"The spirit had developed a distinctly different aroma and smoothness – something traditional maturation simply couldn't achieve in the same timeframe.

"Given its uniqueness, we expect collectors and enthusiasts to be very curious about how this method compares to conventional maturation.
"What's more, our proprietary technique isn't limited to spirits – it also applies to wine, rum, and vodka - and that makes it incredibly exciting."
Each bottle of Domhayn can be traced back to the precise location where its cask rested on the loch bed, ensuring a unique provenance for every release.
"Each bottle comes with the precise coordinates of where its cask rested," Mr Patterson said. "It creates a direct, tangible link between the spirit and the environment that shaped it."
Domhayn have been experimenting with submersion cycles, which can range from minutes to a year or more.
'Submersion causes the cask to compress and decompress, triggering a unique interaction between the wood and the spirit involving both extraction and absorption,' Mr Patterson explained. 'It's a one-off opportunity – each cask can only withstand one dive before the pressure permanently alters it.'
To ensure authenticity and quality, the spirit from each cask undergoes molecular-level analysis at the Department of Chemistry at the University of Oxford.
Mr Patterson added: 'We wanted to go beyond tasting notes and detect for molecular-level changes in the spirit. To do this, samples from each of the casks were tested by the Department of Chemistry at Oxford University using chromatography coupled to mass spectrometry.
'The technique measures differences in the compounds found in samples. The results showed a different molecular composition in the processed samples, providing evidence that our process alters the molecular level profile of the spirits compared to control samples.'
Each unique cask produces no more than 72 bottles, with every bottle presented in a bespoke waxed-cotton 'paper bag,' designed in collaboration with Canadian fashion designer Charlotte McKeough.
"This is something for those who appreciate true rarity, innovation, and a drop of adventure in their glass," Mr Patterson concluded. "It's not just a spirit – Domhayn is a deeply distinctive experience.
'For collectors, connoisseurs and pioneers of taste, we believe Domhayn offers something truly extraordinary.'
The first bottle will be auctioned online on Friday April 25 at www.whiskyauctioneer.com
