Speyside Cask Strength Whisky: Probably the heart of the malt industry, with distilleries almost shoulder to shoulder along the Spey and its tributaries. Speysides can be huge and sherry wooded, with smokiness, great length and complexity. Often the nose is enough to entrance. These malts have had no water added since being placed into cask following-distillation. Their strength can vary with time in the cask due to being stored in either a dry or a damp atmosphere. Cask strength Malts have greater concentration than standard.
