OVEREEM NANOOK X: A TASMANIAN SINGLE MALT SHAPED BY THE ENDS OF THE EARTH

There are whiskies that speak primarily through their maturation, and others whose character is inseparable from the story surrounding them. NANOOK X, the latest release from Tasmanian producer Overeem Whisky, belongs firmly to the latter category. Developed over five years, the whisky grew from a collaboration with polar explorer Dr Geoff Wilson and his ambitious Project Zero expedition aboard NANOOK X, a net-zero vessel conceived to circumnavigate the globe and cross the Arctic Circle.

The relationship between Wilson and Overeem began in 2021 with Dome Argus, a limited-edition whisky created in connection with his Antarctic expedition. That release incorporated Antarctic ice melt, establishing a creative link between whisky and exploration that would eventually lead to NANOOK X. The new expression takes that idea further, drawing influences from Tasmania, the Barossa and the Arctic before returning to Tasmania for its final stages of maturation and bottling.

At the heart of the project is Overeem’s Tasmanian single malt. The distillery, based in south-eastern Tasmania, has built its reputation around long fermentation periods and patient maturation, with the island’s natural environment providing an important part of its production identity. The brand’s official heritage traces its beginnings to Casey Overeem, who established the distillery in 2005 as Tasmania’s fourth distillery. His interest in whisky began earlier, following his first experience of distilling in Norway during the 1980s. Overeem released its first single malt expressions in 2012, working alongside Casey’s daughter Jane, and the family’s involvement continues today through Jane Overeem and her husband Mark Sawford.

That heritage gives NANOOK X a distinctly Tasmanian foundation, but its maturation journey is deliberately international. The whisky begins in Barossa fortified wine casks, selected to provide depth and richness. From there, the project moves north: used whisky casks from Aurora Spirit Distillery in Norway were transported to Tasmania for a second maturation. Aurora Spirit describes itself as the world’s northernmost whisky distillery, located at 69 degrees north beneath Norway’s Lyngen Alps. The distillery began production in 2016, making its Arctic setting an integral part of its identity.

The choice of these casks gives NANOOK X an unusual geographical arc. Its foundation lies in Tasmanian malt and Barossa maturation; its second maturation introduces a connection to the Arctic; and its final preparation returns to the southern hemisphere. It is a literal journey through contrasting climates, rather than simply a thematic reference to exploration.

The final bottling strength also carries a link to the project’s earlier chapter. Overeem uses Tasmanian water together with Antarctic ice melt, echoing the approach taken with Dome Argus and maintaining a connection to Wilson’s Antarctic expedition. The resulting whisky therefore incorporates elements associated with both polar regions, while remaining firmly rooted in Overeem’s Tasmanian production.

NANOOK X is presented in two expressions: Tamed, bottled at 45.5% ABV, and Untamed, bottled at 59.8% ABV. The distinction offers two interpretations of the same underlying journey, one at a more approachable strength and the other retaining a more concentrated cask-strength character.

The naming itself reflects the expedition at the centre of the project. NANOOK X takes its identity from the vessel that will carry Geoff Wilson and his son Kitale on Project Zero. The expedition has been conceived around the idea of combining ambitious exploration with environmental responsibility, with the vessel designed as a net-zero craft. For Overeem, that ambition provided the conceptual framework for a whisky that could embody movement, distance and the meeting of extreme environments.

There is also an important continuity between NANOOK X and Overeem’s wider philosophy. The distillery’s heritage is built around careful production rather than rapid expansion: long fermentation, extended maturation and an emphasis on the character developed through time. Its current range continues to include Port and Sherry Cask Matured single malts, alongside limited and small-batch releases. Overeem’s official heritage notes that earlier releases frequently sold out quickly, contributing to the brand’s following in Australia and overseas.

For those interested in experiencing the distillery itself, Overeem’s official cellar door is located at its current site in Huntingfield, Tasmania, and is open Monday to Friday from 9am to 5pm. The brand also accepts direct enquiries regarding whisky, tastings and tours through its official website.

NANOOK X arrives, then, as a project in which provenance is unusually tangible. The Tasmanian spirit provides the foundation; Barossa fortified wine casks establish an Australian layer of influence; Norwegian casks introduce the Arctic; and Antarctic ice melt completes the geographical circle. Each element belongs to a different point on the map, yet the whisky remains connected by one continuous journey.

That makes the release an interesting reflection of contemporary Australian whisky itself. Overeem’s story began with a Tasmanian distiller pursuing the possibility of producing a single malt capable of standing alongside established international names. More than two decades later, the distillery is using its home-grown foundations to explore a much wider sense of place.

NANOOK X ultimately treats whisky as a vessel for memory and geography as much as maturation. Its story begins in Tasmania, travels towards the Arctic and Antarctica, and returns to the same southern island from which Overeem’s own journey began. In that sense, the release does not simply commemorate an expedition; it translates the idea of exploration into the language of the cask, the spirit and the landscape.
