Aberlour 12 Year Old Double Cask Matured

Probably the weakest Aberlour I’ve tasted. How can a whisky lose character from 10 to 12 years old, unless they just foist lower grade casks onto the “travel” market. This bottle was duty free.
Nose: Dry sherry, dried fruit raisins, fruit cake, cinnamon and hint of liquorish. Taste: more sherry still dry. Very clean in the mouth with some cereal malt but a bit bland. Finish: Medium length, dryish and a touch bitter.
