Created in a bygone era when the Distillery still malted its barley onsite, the smoky, balanced spirit of cask No. 3 was distilled on Tuesday, 25thNovember 1975, and laid down to age in two separate casks – a bourbon and an Oloroso sherry. Those casks were patiently matured by generations of Ardbeg’s skilled warehouse workers over 38 years. Then Ardbeg’s acclaimed Director of Whisky Creation, Dr Bill Lumsden, decided to marry the two casks, creating an even more extraordinary single malt. On 31st March 2014, he transferred their whisky into a single refill Oloroso butt, selected to give only the subtlest of wood influence. There it has remained ever since. Today, more than 46 years after its story began, this single malt is a smorgasbord of sherried, smoky aromas and rich, elegant tastes.

Over the next five years, Ardbeg will continue to mature Cask No. 3 in a secure location on Islay for its owner. Every year, she will receive 88 bottles from the cask. By 2026, this Ardbeg enthusiast will possess a unique vertical series of rare Ardbegs from 1975, aged 46, 47, 48, 49 and 50 years old.

Dr Bill Lumsden, who will oversee the cask’s ongoing maturation, said: “Cask No. 3 is an extraordinary taste of Ardbeg’s past. Its aromas are nutty, herbal and smoky, while its tastes of tar, espresso coffee and spearmint have an astonishing finesse for a whisky of such age. So little stock survives from this era, that this cask really is one of a kind. And its complex flavours are testament to the extraordinary skill of the Ardbeg team who have cared for it over the decades. I look forward to exploring how it continues to evolve over the next five years.”

Industry experts hailed the sale as a demonstration of Ardbeg’s appeal, and the investment value of single malt Scotch. Author and world-renowned whisky expert Charles MacLean MBE said: “This truly unique whisky is a remarkable piece of liquid history – an evocative taste of what Ardbeg was like when it malted its own barley. Many old whiskies can go flat with age. But Cask No. 3 is a really lovely whisky, hugely complex, still having vitality after nearly half a century.”

On Ardbeg’s draw for collectors, he added: “The factors which make a particular whisky investable are threefold: rarity, flavour and variety. And collectors do love Scotch, because of the provenance and history. Furthermore, there is a keen interest in smoky Islay whiskies. And Ardbeg is particularly rare – there just aren’t many bottlings of this age out there. While £16million seems a breathtaking price for a cask of whisky, £36,000 per bottle is not unexpected for whiskies of that age and rarity.”

Becky Paskin, whisky expert and founder of Our Whisky, explained that the strength of Ardbeg’s following and the continuing maturation of Cask No. 3, further increased its desirability. She said: “Cask No. 3 is undoubtedly alluring, and not just because of its own rarity. It hails from a Distillery that has a reputation for creating beautiful liquid, commands a cult status worldwide, and has a firm place in whisky enthusiasts’ hearts. Of the many distilleries in Scotland which have a legacy, a history and a charm about them, Ardbeg is certainly one of those which could command such a high price for a vanishingly rare cask like this. What’s most fascinating is that the owner hasn’t simply purchased an Ardbeg cask, she has invested in a vertical series of bottlings from one single cask, which will develop and mature over the next five years. This is a rare opportunity to witness a cask’s development over time.”
