This is a typical modern designed whisky that tastes like hundreds of other designed whiskies nowadays - the rum cask finish is just for the records and not identifyable on the palate. Average stuff, not worth any extra buck...
The colour is yellow gold and the nose starts rather shy on peaty and autumn floral (dry haystacks) aromas without any rum note that I can find. Even after a significant time of breathing this nose stays rather restrained.
The taste is bitter-sweet on peaty and sugary flavours without any depth and complexity. It is easy to drink, not more. Again I do not find any impact of the rum cask finish, either this was very short or the cask was exhausted already.
The initial mouthfeel is warming but not really coating with a minor drying moment (cold metals, ashes). The finish is long and gets sweeter on barley sugars towards the end. The drying feeling pops up again (cold ashes). Water turns the dram smoother but it strengthens the bitter-drying impressions too. I like the neat dram more.
