Nose: Quite soft and mellow, with caramel, brown sugar and tropical fruits really standing out from the typical Dewar's profile. I'm surprised it smells so much like rum after 6 months in rum casks. Nevertheless, it smells just fine for what it's written out to be. Taste: Smooth and immediately on the sweet side. Lots of caramel and brown sugar here, plus tropical fruits. The classic Dewar's barebones are hiding just beneath the surface though. This whisky really feels like they mashed two very different drinks together. It's not bad, but not a very finely crafted blend. Finish: Short and sweet. That is, very much on the sweet side of things. Final thoughts: This tastes like an honest 8 years in blends plus 6 months in rum casks. It's a decent enough blend where the grain doesn't overpower the palette proper. If you like caramel and sugar in your whisky then dive right in. I would rather have some proper malt though. Oh and this is undeniably preferable to the Tullamore Rum Cask finish (yeah, the so-called XO that tastes about half as old as this Dewar's).
