Dewar’s Double Double 37 Year Old Blended Malt Scotch Whisky is a strictly limited-edition whisky created by our unique 4-stage ageing process, and is also the first in a special Collector’s Series celebrating Scotland’s most famous whisky regions. The landmark Double Double 37 is a rare blended malt finished in Oloroso sherry casks that once held Aultmore single malt whisky from the region of Speyside. As befits a whisky of this quality, it is presented with two Baccarat Massena crystal tumblers.
