A Scottish drinks innovator is taking its next bold step after successfully maturing spirits beneath the waters of Loch Ness.

Domhayn, derived from the Gaelic word for deep, has already proven that submerging oak casks at 200 metres can transform flavour, producing smoother, more integrated rum and whisky.

Their Loch Ness-matured releases have earned international attention and industry recognition, including a place in the Top 50 most innovative spirit launches of 2025 by The Spirits Business.

Now, the company is pushing into uncharted territory.

GOING WHERE NO SPIRIT HAS GONE BEFORE

From 9 April to 12 May 2026, Domhayn will launch a 30-day Kickstarter to fund a world-first experiment: exposing a spirit-filled cask to pressures equivalent to 1,000 fathoms (1,830m or 6,003 ft): the deep-sea “abyss” once explored by pioneers like James Clark Ross.

The goal is to test how extreme hydrostatic pressure can further evolve flavour beyond what’s possible through traditional ageing, or even by the firm’s own Loch Ness trials.

With growing interest from whisky enthusiasts in the U.S. and Canada, the project is now inviting a global audience to take part in what could become a landmark moment in modern Scottish spirits.

FOUNDER PERSPECTIVE

Founder James Patterson said: “Submerging casks into Loch Ness started as a bit of curiosity, just wanting to see if pressure would actually change anything. It did.

“This next step is really about understanding how far that effect goes, and whether we’re only just scratching the surface.

““It’s part science experiment, part modern Scottish innovation story, and we’re inviting supporters from around the world to back our journey and maybe even taste the results for themselves.”

PART SCIENCE, PART MODERN SCOTTISH INNOVATION STORY

The experiment will take a phased approach. The first trials will be carried out on land using a controlled hydrostatic pressure chamber.

James explained: “These initial tests will let us recreate deep-sea conditions in a controlled environment, so we can see exactly how the casks respond as pressure builds,” he said.

“If that goes well, we’ll move on to a full ocean experiment and try to reach those abyss-level depths for real.”

SCIENTIFIC BASIS

The process builds on established principles of physics involved in traditional cask maturation, introducing pressure as an additional variable.

Domhayn has discovered:

Increased pressure compresses the oak structure of the cask
Air pockets within the wood and liquid contract and expand during pressure cycles
This movement drives the spirit deeper into the wood and back out again

The result is a different pattern of interaction between the spirit and oak, leading to measurable changes in chemical composition.

WHY 1,000 FATHOMS

The 1,000 fathom mark has historical significance in ocean exploration.

In the 19th century, expeditions led by figures such as James Clark Ross recorded some of the first measurements beyond this depth, an area often referred to at the time as “the abyss”.

James added: “The project is not just a technical experiment, it’s also a nod to the early pioneers of ocean exploration. We’re curious to see how far we can push the science, while connecting to that history of discovery.”

INTERNATIONAL INTEREST AND FUNDING

Domhayn has attracted early interest from whisky enthusiasts and collectors, particularly in the United States and Canada.

The Kickstarter campaign will allow backers to support the experiment and follow its progress, with the potential for limited releases if the project is successful.
