Rare Find Unveils Three Single Cask Glenglassaugh Whiskies

Rare Find will release a new collection of three single cask Glenglassaugh whiskies through selected stockists from 30 July 2026. The Edinburgh-based independent bottler said the collection focuses on different cask finishes applied to the coastal Highland distillery’s spirit.

The release includes a 10-year-old Glenglassaugh finished for 19 months in a first-fill Foursquare rum barrel. It has been bottled at 54.6% ABV, with 234 bottles available.

Two further whiskies are both nine years old and were finished for 11 months in octave casks. One used a first-fill Madeira octave and has been bottled at 52.7% ABV, with 53 bottles available, while the other used a first-fill ruby port octave and has been bottled at 52.2% ABV, with 48 bottles available.

Rare Find said all three whiskies have been bottled at natural cask strength, with natural colour and without chill filtration.

James Zorab, Whisky Supply Manager for Rare Find, said: “Glenglassaugh has such a distinctive spirit style – vibrant, fruit-forward and with a subtle coastal freshness – which makes it incredibly exciting to explore through different cask finishes.”

He added: “This Collection is about showing the versatility of that spirit and how carefully selected wood can reveal completely different facets of its character. Together, they represent exactly what Rare Find seeks to create – exceptional single casks that offer something distinctive, memorable and genuinely worth discovering.”

Glenglassaugh is based near Sandend Bay in Aberdeenshire and is usually described as a coastal Highland distillery. Rare Find said its latest collection was intended to show how rum, Madeira and ruby port casks can shape different versions of the same distillery character.
