"Speyside, the undisputed center for whisky in Scotland, boasts the highest concentration of distilleries (more than half the distilleries in Scotland are located in Speyside). Although the Speyside region is geographically part of the Highlands, it is considered a separate region because of its unique characteristics. The region received its name from the river Spey, which cuts through the area. Many of the distilleries use water straight from the river Spey in their production process. Speyside scotch are thought to be the country's most complex, and is known for their sweetness and elegant flavors and aromas."
