Springbank's 18 Year Old is one of Campbeltown's most sought-after annual releases, and this edition is matured in a carefully balanced mix of bourbon (50%), sherry (45%) and a small portion of rum casks (5%). It's a recipe that lets the distillery's signature character carry the whisky, the bourbon and sherry building depth, the touch of rum adding a subtle lift, in the layered, textured style that keeps Springbank drinkers coming back.
