Cutty Sark Centenary Edition is a mature blended Scotch whisky bottled at 23 years old and released at cask strength. That means it was bottled without being reduced to a lower drinking strength, giving it a fuller, more concentrated style than many standard blends.
For a novice drinker, this is likely to feel richer and more powerful than an everyday blended whisky, with the extra age suggesting greater depth and oak influence. Its high ABV also means a small splash of water may help open it up in the glass.
