There are four categories of scotch malt whisky, classified according to geography: Highland, Lowland, Islay, and Campbeltown. The Highlands region is the big show, the area with the most distilleries by far and most of the ones everybody's heard of (The Glenlivet, Glenfiddich, The Macallan, Glenmorangie, and so on). The majority of the other well-known ones come from Islay (pronounced EYE-la), the most important of whisky islands, among them Laphroaig, Bruichladdich, and Bowmore. Lowland whiskies are marginal to the American consumer. And then there's Campbeltown.
