The 25 Year Old is the senior age-stated expression in the Glengoyne core range. Like its siblings it relies entirely on first-fill and refill sherry casks for its maturation, and like them it is bottled without chill filtration or added colour. Unusually for an aged single malt at this price, it carries an above-standard strength of 48%, reflecting the distillery's confidence in the spirit's body after a quarter century in European oak.
Glengoyne's commitment to slow distillation, with stillman Robbie Hughes and his predecessors running the spirit at a pace measured in drips, gives a clean and oily new make that takes well to long sherry maturation. The unpeated character means there is nothing to obscure the interaction between spirit and wood, and at twenty-five years that interaction has had ample time to settle into something closer to a marriage than a courtship.
The nose is deep and cohesive: dark cherry, espresso, fig and walnut oil over old oak. The palate is sumptuous, concentrated and beautifully integrated, moving through prune, dark chocolate, cinnamon and orange marmalade. The finish is exceptionally long, drying through tobacco leaf without ever turning bitter.
This is a serious bottling and priced accordingly, but among 25-year-old single malts from sherry-led distilleries it offers genuine value. The slow distillation and the patient cask choice have produced a whisky of quiet authority. A benchmark Highland sherry malt at this age.
