Aberfeldy 21-year-old St-Emilion French Wine Cask Finish is a Highland single malt whisky matured for 21 years and given a finishing period in French red wine casks from Saint-Emilion. For a novice drinker, that usually suggests a softer malt base layered with extra fruit and oak influence from the wine cask.
Expect a mature, rounded style rather than anything smoky. The age points to added depth and polish, while the wine-cask finish is intended to bring richer fruit character and a different oak accent to the whisky.
