Campbeltown Cask Strength Whisky: On the famous Mull of Kyntyre two distilleries remain, Glen Scotia and Springbank, the latter of which occasionally produces the Malt known as Longrow. Springbank is a benchmark of a Malt, Longrow a gem to be appreciated when available. 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.
