The Singleton of Glendullan 38-year-old is a well-aged Speyside single malt released by Diageo as part of its Special Releases series. Bottled at cask strength, it offers a more concentrated style than many standard single malts, with the high ABV allowing drinkers to explore it neat or with a little water.
At 38 years old, this is a mature whisky likely to show layered oak influence and the depth that can come with long ageing. For a novice, it is best understood as an old, powerful single malt made for slow sipping and close attention.
