Dewar's has pioneered the 'double ageing' process, with all the blends in the range undergoing a secondary resting in oak casks to marry the flavours and bring extra smoothness to the blend.
With the limited edition new 'Double Double' range, this process has become an art form, with a 'quadruple aging' or 'double double' aging process created by Dewar’s master blender Stephanie Macleod.
Firstly, the malt whiskies achieve their required age, and are mixed together and returned to an oak cask. The same happens to the grain whiskies. Then the two whisky types are blended together, and returned to an oak cask for a secondary double aging period. Finally, the blend is finished in an ex-Sherry cask.
This 21-year-old release has been finished in Oloroso Sherry casks, giving the whisky “subtle notes of cinnamon and ripe vine fruits with a silky smooth finish”.
Tasting notes from Alex, one of our tour guides: Double Double aged for ultimate smoothness is the tagline for this range of whiskies and that is certainly true of this dram. An incredibly easy sipping whisky with no spirit kick to it whatsoever, despite the higher ABV. A sweet buttery nose opens onto big sherry notes of raisins and cinnamon. On the palate, dried orange peel with cloves graduates into a candied sweetness. A lingering dram that will keep you warm in the Winter and would mix well with bitters and sugar to make a Christmas Old Fashioned. Smooth enough to be accessible to a novice but packed with enough flavour to hook a connoisseur.
