Diageo has added two aged single malts from Convalmore and Dalwhinnie to Rare Series, its evolving collection of rare scotch whiskies. The new chapter includes a 41-year-old Convalmore from Speyside and a 36-year-old Dalwhinnie from the Highlands, following the collection’s debut in April.
The drinks giant built this second chapter around Scotland’s remote corners and the harsh Scottish winter.
“Both of these releases demonstrate what happens when exceptional Scotch is left to quietly endure and thrive against the elements. From a lost Speyside icon to one of our highest and coldest distilleries, decades of weathering Scotland’s bracing winters have drawn out remarkable depth, transforming intense cold into an enveloping, honeyed warmth and complex spice. Shaped by nature and time, they embody the very essence of our craft,” said Dr. Craig Wilson, Diageo master blender, in the official press release.

READ THE STORYConvalmore 1984 Rare Series comes from a ghost distillery in Scotland’s northeast. The liquid matured in a single American oak cask. Convalmore filled that cask shortly before the distillery closed in 1985.
Diageo says the original producer had bottled the whisky only five times before.
The distillery sat in Dufftown, in the heart of Speyside. During its lifetime almost the entirety of its stock was reserved for blending – at one time it was a key malt in the make-up of the Black & White blend.

This vintage has appeared before. Diageo’s Prima & Ultima second release included a vatting of three refill American oak hogsheads filled on 22 November 1984.
At The April launch, Julie Bramham, managing director of Diageo Luxury Group, added: “Rare Series is an ode to Scotland’s rich whisky heritage and its enduring influence on the world of luxury, where rarity is not created, but revealed over time. The collection as such, is defined by provenance and character.”
Dalwhinnie 1989 Rare Series is a 36-year-old single malt. Dalwhinnie ranks among Scotland’s highest and coldest distilleries.
The whisky spent time in American oak hogsheads seasoned with Amoroso sherry. It then received an unusually long finish of more than four years.
Official notes from the brand highlight honeyed richness and the scent of wild moorland.
Dalwhinnie has a long role in Diageo’s single malt strategy. During the late 1980s, United Distillers launched a series of benchmark expressions of single malt scotch whiskies from six distilleries across Scotland , and Dalwhinnie was one of them.
The announcement gave no pricing or bottle counts for either release.
Rare Series first appeared on April 30, 2026. Its first chapter featured Blair Athol 1991, Clynelish 1983, Caol Ila 1983, Talisker 1992 and Glenury Royal 1970 . At 55 years old, the Glenury Royal is the oldest single malt ever released by the company.
Diageo sold the first chapter through its Private Client teams, including fine wine and rare whisky experts Justerini & Brooks. The company draws on more than 10 million casks across over 30 distilleries .
Diageo says it will release future editions only when these whiskies reveal their finest character, as determined by Diageo’s Master Blenders .
