This is a 23-year-old single malt Scotch whisky from Pulteney, bottled by independent bottler Decadent Drams at a cask-strength 57.2% ABV. The refill barrel maturation suggests the oak is likely to play a supporting role rather than dominate the spirit.
For a novice drinker, that often means a whisky where distillery character can remain clear, with concentrated flavour from age and strength. Expect a mature style that may benefit from a little water in the glass.
