Glenfiddich Grande Cru 23 Year Old is part of the Grand Series, produced from single malt matured for a minimum of 23 years in American oak ex-bourbon casks at the Dufftown distillery. The expression is then finished in rare French cuvée oak casks — casks formerly used to hold fine French wines — lending the aged Speyside spirit additional layers of dark fruit, vine blossom, and oak complexity that are distinct from sherry or bourbon wood. 'Grande Cru' references the classification of France's finest wine terroirs and signals the ambition of this premium cask-finished expression. Bottled at 40% ABV as part of the Glenfiddich Grand Series.

Glenfiddich Distillery was founded on Christmas Day 1887 by William Grant in Dufftown, Speyside, Scotland — a location chosen for its access to the Robbie Dhu spring water. The house has remained in the ownership of the William Grant & Sons family for five generations, making it one of the very few major Scotch whisky distilleries still in the hands of the family that founded it. Glenfiddich is the world's most-sold single malt Scotch whisky and has been central to the development of cask finishing in the industry — its Malt Master David Stewart pioneered the double-maturation technique in the 1980s, which is now used across dozens of expressions.
