This is an 18-year-old single malt Scotch whisky from Bruichladdich, bottled at a robust 57.3% ABV. An Oloroso sherry finish suggests added layers of dried fruit, nuttiness, and spice alongside the distillery's underlying malt character.
For a novice drinker, expect a fuller and richer style than a standard ex-bourbon-matured malt, with the higher strength likely making it more intense and concentrated. Adding a little water may help open up the whisky and soften the alcohol.
