The decisive influence of famous, quality Speyside malts gives Cutty Sark its fresh, lightly peated style. Cutty Sark is matured in the Highlands of Scotl&, principally in American oak casks which have been used previously for Oloroso sherry. It is these casks which give Cutty Sark its soft vanilla notes & light colour. Cutty Sark's consistent balance is achieved by returning the mature, blended single whiskies to cask to settle for a further six months before bottling.
