Every cask silently slumbering in our on-site warehouses is meticulously monitored throughout its maturation journey, ensuring the whisky is bottled at its optimum. This process allows us to find some hidden gems: casks that are developing rather special and distinctive characteristics. These unique whiskies merit being showcased individually so as to capture the interesting nuances and unique personality delivered by the cask’s DNA: its history, oak genus and provenance. For these bottlings, we believe it’s essential to present the spirit at cask strength to deliver a drinking experience that transports you to the depths of our warehouses in Speyside; as if you were sampling directly from the cask.

An incredibly fine dram with a divine taste. This Highland Glencadam was personally selected by Premium Spirits and released in a numbered edition. The cask was personally selected on site after a thorough analysis.

Glendalough Peated Pot Still is a bold fusion between Irish whiskey tradition and innovation, redefining the Pot Still style. It is made from malted and unmalted barley, distilled in traditional copper pot stills, and aged for over seven years. The introduction of peated malt, smoked during drying, adds a bold twist, blending delicate smoke with the characteristic spices and creamy texture of Pot Still whiskey. Crafted and bottled at 46% ABV, it begins its maturation in ex-bourbon American oak casks. It then spends an additional four years in virgin oak casks. This long aging process imparts notes of toasted oak, rich vanilla, and warm spices, perfectly balanced by a subtle peated smoke. A very special edition, available for a limited time only.

There is no more Irish whiskey than Pot Still; thus, Glendalough Distillery feels it is fitting to age it in Irish Oak. Glendalough Distillery is proud to play its part in bringing back the use of Irish oak for whiskey cask-making. This most quintessentially Irish style of whiskey, pot still, is first matured in ex-bourbon casks, then in Irish Oak felled in the mountains around the distillery.
