Isla Marambio - World's First Whisky Matured In Antarctica


13th October 2025
World's first whisky matured in Antarctica unveiled.

After three years of ageing under some of the harshest conditions on Earth, the world’s first whisky matured in Antarctica has been revealed — a groundbreaking venture conceived by whisky entrepreneur Daniel Monk, founder of Cask World, and made possible through a partnership with La Alazana Distillery in Argentina. La Alazana Distillery was founded by Lila and Néstor Serenelli in Argentina’s Chubut Province and is a trailblazing South American whisky producer, crafting small-batch single malts that reflect the distinctive character of Patagonia’s climate.

The whisky, named Isla Marambio, has just been bottled at La Alazana Distillery and will form part of Cask World’s forthcoming 8 Continent Series — set to become the first-ever collection of whiskies matured across all seven continents, plus Antarctica, when it launches in 2026.

An eight-year-old Argentinian single malt, Isla Marambio began its life at La Alazana Distillery in Chubut Province, where it was distilled and aged for five years in virgin oak casks. It was then transferred to ex-bourbon barrels and shipped to Base Marambio, an Argentine research station on Seymour Island, to undergo three years of secondary maturation under extreme Antarctic conditions.

The casks were stored in an uninsulated hut, fully exposed to temperatures fluctuating between –35°C and +10°C. Over time, they developed a frosted exterior, a striking testament to the volatile environment that shaped the whisky’s maturation. Once the Antarctic ageing was complete, the casks were returned to Argentina for bottling.

Isla Marambio will be released in limited quantities next year as part of the 8 Continent Series, which also includes expressions matured in countries such as India, South Africa, Brazil, Canada, and Wales.

Lila Serenelli, co-founder and distiller at La Alazana, said: "We already know it's different. When I was decanting it there was a very special floral note that is not so strong in our whisky usually. There’s something that I think has happened. I can’t assure it, but it’s a thought… although there are temperature variations, the mid temperatures tend to be under zero. This movement allows extraction and oxidation, but holds the ethanol in, and reduces evaporation. We’ll have better insight when we measure the ABV of the vatted whisky.

"I can say that it’s very cold, very far, extremely vast and it’s so far away that it’s shocking. When I was standing there, staring at the frozen sea, I just got this aching in my heart that pulled tears from my eyes and I just knew that our whisky spent three whole years there and that was just it."

Daniel Monk, founder of Cask World and creator of the 8 Continent Series, said: "It made perfect sense to work on this project with Néstor and Lila Serenelli in Patagonia. They’re pioneers who, like me, believe in doing something that’s never been done before. I was in their garden in Argentina when I shared the idea of maturing whisky in Antarctica - they didn’t hesitate. They are the heroes who made it possible, overcoming every challenge to make the Antarctic maturation a reality.

"Together we made history by sending casks of La Alazana whisky to Base Marambio, where they were matured on the Antarctic continent. For me, Antarctica isn’t just a frontier — it’s a symbol of purity, endurance, and balance.

"This collection I’m pulling together - the 8 Continent Series - will be more than a set of whiskies; it will be the story of the world told through flavour, climate, and collaboration. For me, the dream of maturing whisky on every continent isn’t just about whisky - it’s about what it represents: the spirit of exploration, connection, and pushing the limits of what’s possible. My life has always been about daring things most would call impossible - from cycling across continents to overcoming addiction, sailing the Atlantic circuit with my children, and building a whisky business that connects people and places.

"When I discovered so many countries making whisky few had ever heard of, I felt compelled to visit the distilleries and meet the people behind them. From that moment, I knew it was ‘new world whiskies’ I wanted to focus on and to shine a light on this remarkable period of growth and creativity."

The Antarctic project was conducted with the support of Argentina’s Ministry of Defence and Armed Forces, who coordinated the transportation of the casks to and from Base Marambio aboard a Lockheed C-130 Hercules aircraft, flying between Buenos Aires, Río Gallegos, and Antarctica.

This pioneering experiment not only marks a milestone for global whisky maturation but also exemplifies a shared spirit of innovation — pushing the boundaries of what’s possible in the world of whisky.
