This is a cask-strength single malt Scotch whisky from Balblair, distilled in 1990 and bottled at 21 years old. As a single cask release, it comes from one individual cask rather than a large batch, so it may show a more distinctive character than standard bottlings.
At 57.9% ABV, it is likely to be full-bodied and intense, with added concentration from its higher strength. Older Highland single malt often offers a more layered, mature style, and a small amount of water may help open up its aromas and flavour for new drinkers.
