Cask Collection
Single cask whisky is at the heart of A. D. Rattray. We go to great lengths to source interesting and unusual casks from the six traditional whisky regions of Scotland. Each distillery represented is different and every cask is unique.
We curate 4 releases of our Cask Collection per year, choosing between 6 and 8 casks for each collection. Our cask are evaluated over time and are selected for inclusion only when we judge they have reached the peak of perfection.
Once a cask is selected, the spirit is rough filtered, removing any fragments of charred wood left behind by the cask, and then bottled at natural colour and cask strength, with no chill-filtration. There are therefore a limited number of bottles from each cask.
This process retains the true essence of the distillery character and cask maturation for your enjoyment.
Latest Release
A. D. Rattray’s 81st Cask Collection release for Autumn 2026 explores the art of flavour - the way individual elements combine, contrast and evolve to create a whisky’s unique character.
In whisky, we often describe flavour through individual notes: fruit, spice, sweetness, smoke, cereal and oak. Yet the most memorable whiskies are rarely defined by a single characteristic. Their appeal comes from the relationship between those elements – the way richness can be balanced by freshness, sweetness by savoury depth, or intensity by elegance.
Independent bottling allows us to explore these relationships across individual single casks. From coastal sweetness and maritime smoke to rich cereal notes, bright fruit and refined spice, Cask Collection 81 showcases whiskies where flavour is not simply found, but patiently revealed through maturation and time.
As with all our Cask Collection releases, each cask is presented at natural strength, undiluted and unfiltered. These selections celebrate the complexity of flavour – not as a checklist of individual notes, but as the harmony created when they come together.
