Old Particular Benrinnes is a Speyside single malt bottled from a single cask at 48.4% ABV. An 11-year-old whisky like this will usually show a fairly direct house character, with the individuality of one cask rather than a large batch.
For a novice drinker, expect a style that can lean rich and weighty for Speyside, with malt, fruit, and oak likely playing the main roles. The label notes an "other cask" maturation, which suggests some cask influence beyond the most standard descriptions, but the exact flavour impact depends on that individual barrel.
