Glendalough 25 Year Old Single Malt Irish Oak Finish


750ml, bottle

Glendalough 25 Year Old Single Malt Irish Oak Finish is a rare and luxurious expression from the Glendalough Distillery. This whiskey breaks tradition by being aged for a quarter-century in a combination of heavily charred ex-bourbon barrels, bold Oloroso sherry casks, and finally finished in virgin Irish oak. This unique maturation process results in a complex and flavorful whiskey unlike any other Irish single malt.



Initial Impression: Look for a welcoming sweetness with prominent notes of vanilla extract and hints of caramel. These sweet notes are likely a courtesy of the initial aging in heavily charred ex-bourbon barrels. As you delve deeper, expect a touch of baking spice like cinnamon or nutmeg to emerge, adding a hint of complexity.

Deeper Sniffs: This is where the influence of the Oloroso sherry casks starts to unfold. Hints of dried fruit like raisins, prunes, or even figs might appear, adding a richness and depth to the initial sweetness. Depending on the specific cask used, a touch of nuttiness like almonds or walnuts could be present, hinting at the influence of the sherry. Some enthusiasts detect a subtle note of dark chocolate or even a touch of coffee bean, adding another layer of intrigue.

A Touch of the Unexpected: Finally, the virgin Irish oak finish makes its presence known. Expect a burst of fresh wood character, with hints of freshly cut grass or even a touch of menthol. This adds a lively spiciness and a touch of vegetal earthiness that differentiates this whiskey from traditional Irish single malts.


First Sip: The body can range from medium-bodied to full-bodied depending on the specific batch. The extended aging and combination of casks contribute to a weightier mouthfeel compared to younger Irish whiskeys. The unspecified ABV (likely around 46%) delivers a gentle warmth that complements the flavors. The sweetness from the aroma translates onto the palate, with vanilla and caramel taking center stage. Hints of honey or butterscotch might also emerge, influenced by the bourbon casks.

Midpalate: As the whiskey opens up, the complexity truly shines. The dried fruit character from the Oloroso casks becomes more pronounced, potentially revealing additional notes like dates or apricots alongside the initial raisin or prune. The touch of nuttiness from the aroma becomes more noticeable on the palate, adding a textural element. The dark chocolate or coffee hints might become more prominent, depending on the specific cask used. This is where the influence of the virgin Irish oak truly comes alive. Expect a wave of lively spice, with hints of black pepper or even a touch of ginger. The fresh wood character emerges, adding a touch of earthiness and balancing the sweetness from the earlier stages.


Lingering Flavors: The sweetness fades gradually, leaving a pleasant warmth and a touch of oaky dryness on the palate. Hints of dried fruit and dark chocolate linger alongside a subtle spiciness from the virgin oak. The overall finish is long and incredibly satisfying, showcasing the harmonious marriage of time, traditional casks, and the innovative use of virgin Irish oak.
