[Update:] I hadn't had a dram of Curiositas for over 2 months. I'm not sure it is purely from oxidation in the bottle, or if the summer heat played a role, but after this time between drams it is as if I bought a completely different whisky! If it is just oxidation, then it would mean that the normal ratio of 1min/1year does not apply to the Curiositas, and that this whisky requires significantly more time to open up. I have therefore updated the review noting the differences between the fresh bottle (FB) and the oxidised/aerated bottle (AB).
Nose: The FB started with a dominating peat hit, which was more medicinal than bonfire in character. Underneath this were citrus and pear notes with a pleasant saltiness. The AB peat is far more restrained, with a pleasant, soft smokiness that is almost devoid of the medicine. Here the pear and salt notes are far more prominent. Both noses were enjoyable albeit for different reasons, the FB was rather one dimensional but was BIG, the AB is far more balanced and nuanced. I score them both approximately the same, even though they are rather different.
Taste: The FB, once again, started with a big, enjoyable peat punch with an accompanying peppery senstation. However this gave way to a slightly off sourness and some light herbal notes. The AB had none of these off-notes, the peat was, once again, reduced but the pear and citrus notes from the nose continued into the taste this time around. Here the AB is clearly superior to the FB.
Finish: The FB ended very quickly and was defined by a grassy bitterness, underneath which the smoke lingered. The AB eschewed this bitterness for a more prominent, enjoyable smokiness. Once again the AB was far more enjoyable.
When I first reviewed this I couldn't understand why Jim Murray had scored this whisky so highly and I surmised that it was because he didn't swallow and therefore only experienced 'the good bits'. However after the experiencing the AB expression, things make much more sense.
I originally scored the FB 83, which was an aggregate of the good nose and arrival, but disappointing development and finish. I would score the AB 87.
