All in all an excellent dram both to sniff and to sip, but quite expensive for a NAS bottling. Give me some info about the content of your releases, Diageo and I most probably will rate the price dimension better - but NAS to me reads simply: Never Accept Stupid marketing!
The nose is quite nice on fruity (the Oban trademark oranges and some pears) and grassy (heather, summer flowers) aromas pepped up by light but delicious OBFs (old bottle flavours, I did not expect that in a NAS edition. So it seems Diageo added some older casks to the batch. Hey, another good reason to publish some info about the content!).
The taste is smooth and mellow as well, again on this fruity/grassy profile like the nose. Additional nice barley sugary (not honey), dark chocolate and spicy (peppery) flavours develop over time, all very balanced and in harmony.
The dram arrives on the palate smooth and mellow, really nice. Even some kind of (at least tongue-) coating takes place. Not too bad... The finish is of medium length and comes in different lovely waves, very enjoyable.
