This vast region extends to the north of a line from Greenock to Dundee and offers a wide variety of landscapes. The mountains (notably Ben Nevis and the Grampians) and valleys contrast dramatically with the lakes of Perth and Aberdeen. The whisky-producing Highlands can be divided into four sub-regions. The southern Highlands, with light, fruity single malts. The western Highlands with spicy, single malts tasting of the sea air, like Talisker from the isle of Skye, or more salty and smoky, like Oban and Ben Nevis.
