Scotch across the regions that define it. Islay peat from Lagavulin and Laphroaig, maritime smoke from Talisker on Skye, sherried Speyside from Aberlour, Glenfiddich, Glenlivet and BenRiach — and the blends that built the category: Johnnie Walker, Chivas Regal, Dimple, Monkey Shoulder and Royal Salute.
Three terms worth separating. A single malt is malted barley from one distillery. A blended Scotch marries malt with grain whisky from several distilleries, which is why it is usually lighter and cheaper. A blended malt — Monkey Shoulder is one — is several malts with no grain whisky at all.
Region is a rough guide rather than a rule, but it holds often enough to be useful: Islay for peat and iodine, Speyside for sherry and orchard fruit, the Islands for salt and pepper. Every bottle lists its distillery, region and ABV.
