Four separate agings, not one, define Dewar’s Double Double 38 Year Old, a limited-edition blended malt Scotch whisky from the Collector’s Series. Master blender Stephanie Macleod marries Islay and Highland single malts aged at least 38 years, rests the marriage back in its original casks, folds in a reserved parcel of the previous 37-year release, then finishes everything in Pedro Ximnez sherry casks that once held Royal Brackla. Bottled at 48.8% in a 375ml decanter, the whisky moves from white flowers and citrus into creamy vanilla, toasted cereals and gentle smoke, closing on dried figs, plum and dark chocolate. This is a collector’s pour in every sense serve it neat, in small measures, for people who will understand what they are holding.
