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 79th Cask Collection release for Spring 2026 brings together five individual casks, each drawn from distilleries more commonly encountered as part of a vatting or blend.
Over the past few months, we’ve been quietly assembling a vatting for a forthcoming special release - sampling, adjusting, and crafting a small-batch whisky from a selection of individual casks. It’s a process that reminds us just how much of Scotch whisky is shaped by the bottler: balanced, layered and refined through blending.
Blending certainly has its place. It creates consistency, harmony and a recognisable house style. But every now and then, it’s worth stepping back from a finished composition to consider the individual casks that make it possible - and this release does just that.
Each of the five casks in Cask Collection No.79 is presented as it was found: single cask, natural strength, undiluted and unfiltered. Through single casks, we take a closer look at the finer details - a glimpse beneath the surface of a typical release.
These are the building blocks: character, texture and structure at the heart of each distillery’s style, before they are shaped into something broader. Together, they offer a different perspective - not a polished core expression, but the singular character of a cask that must be harnessed to create the whiskies we know and love.
