Production & Heritage

Willowbank Distillery operated in Dunedin on New Zealand's South Island until its closure in 1997, making it the last operating whisky distillery in the country at that time. The South Island 25 Year was distilled from 100% New Zealand malted barley in copper pot stills, then laid down in American oak ex-bourbon barrels where it matured for a quarter century. The New Zealand Whisky Company acquired these specific barrels in 2010 from storage in an old airplane hangar, rescuing irreplaceable stock from a distillery that will never produce again — making every remaining bottle a finite piece of New Zealand's whisky history.

Tasting Notes

Aroma: Opens with subtle smoke and charcoal before giving way to yellow fruit and drying grass. Deeper investigation reveals red pepper, fresh bread, and roasted vegetables — an unusual and intriguing aromatic profile that reflects both its Southern Hemisphere origins and extended maturation.

Taste: The entry is gentle and round, led by sweet malt and golden fruits with a thread of vanilla from the ex-bourbon oak. The mid-palate becomes more complex, introducing walnut, oily wood, and a light peat influence that never dominates. A touch of brown sugar emerges toward the peak, lending warmth and a dusky, restrained sweetness.

Finish: Light and silky in texture, closing with delicate oak and lingering sweetness rather than any harsh tannin. The 25 years of aging have smoothed every edge, leaving a clean, measured conclusion that invites reflection.

How to Drink South Island 25 Year

A whisky of this age and rarity is best enjoyed neat or with a few drops of water to open the more elusive aromatic layers. The 40% ABV makes it immediately approachable without dilution, though water can accentuate the golden fruit and bread notes. For those inclined toward mixed drinks: a Whisky Highball with quality soda preserves the delicate malt character; an Old Fashioned benefits from the inherent vanilla and brown sugar sweetness, requiring minimal added sugar; and a Bobby Burns pairs the malt's subtle smoke with sweet vermouth and Bénédictine for an elegant Scotch-style cocktail with a Southern Hemisphere twist.

Best For

• Gifting a whisky collector who values rare or discontinued distillery bottlings
• Marking a 25th anniversary or milestone with a spirit of matching age
• Expanding a tasting library with a Southern Hemisphere single malt
• After-dinner contemplative sipping alongside a fine dessert

Frequently Asked Questions

What does South Island 25 Year taste like? It delivers sweet malt and golden fruits up front, followed by walnut, vanilla, and a restrained peat influence, finishing silky and light with delicate oak sweetness.

How does South Island 25 Year compare to Balvenie Caribbean Cask? Reviewers have noted similarities in the round, fruit-forward sweetness, though the South Island 25 Year is drier and carries a light smoky edge that the Balvenie lacks. The Balvenie draws tropical character from its rum cask finish, while the South Island derives its complexity from 25 years in ex-bourbon American oak.

Is South Island 25 Year good for sipping neat? Yes — bottled at an accessible 40% ABV with 25 years of maturation softening the spirit, it is purpose-built for neat drinking and rewards slow, attentive sipping.

Where is South Island 25 Year made? It was distilled at the Willowbank Distillery in Dunedin, located on the South Island of New Zealand, before the distillery permanently closed in 1997.

What foods pair well with South Island 25 Year? Aged cheddar complements the vanilla and oak character; smoked salmon echoes the whisky's subtle smokiness; walnut tart mirrors the nutty mid-palate notes; dark chocolate with sea salt highlights the brown sugar sweetness; and roasted root vegetables align with the earthy aromatic profile.

What sizes does South Island 25 Year come in? This expression is available in a 375ml half bottle, making it accessible for those who want to experience a rare aged whisky without committing to a full-size bottle.

Is South Island 25 Year worth the price? It positions as a premium expression within the aged single malt category, and its value is driven by genuine scarcity — the distillery is permanently closed and remaining stock is finite, making it a collectible as much as a drinking whisky.

Why South Island 25 Year?

This is not simply a well-aged whisky — it is the product of a distillery that no longer exists, drawn from barrels that were rescued from an airplane hangar and can never be replicated. As the first single malt outside Europe and Japan to reach a 25-year release, it occupies a unique position in world whisky. Critical praise from Jim Murray and Charles Maclean validates its quality beyond mere novelty. For collectors and serious drinkers, the South Island 25 Year represents a vanishing piece of New Zealand's distilling heritage in a category where authenticity and provenance matter more than volume.
