I tried it with a friend shortly after the show, both of us like Octomore and had already tasted a couple of delicious yummy xy's and thought the usual 100 € was painful, but quite appropriate. And we had hoped for something delicious from the 10's. It was puff cake.
Not because he had "only" 80.5 ppm, it was already a decent, heavily heavily peated whisky, but maybe more in the 50/60 € league. The double time in the barrel has taken him a lot, but nothing relevant given. And I do not mean peat-and-volt boobs, but really great, partly pictorial taste experiences that I had with some of the younger Octos, and even the more modest of them I found better than the 10s.
Maybe the optimum for Octomore + good barrels is easy at 5 years and it has a reason why you get the now (early 2019), in contrast to some other limited Islay NAS from the time for a whopping 300 ...

Sweet peat and lite fruit in the background on both the noise and palate. Overrated and over priced. Found many other Octomore releases much better and for half the price. 

Octomore 10 years old is a unique and highly refined dram that combines the power of the heaviest peated barley in the world with the purity and elegance of Bruichladdich's whisky. This is a dram for the connoisseur.
Peat: 80.5 ppm.

Nose:  Creamy, citrus, clean peat, vanilla

Palate:  Balanced, clean, creamy, more peat and citrus, vanilla.  Not a big peat monster.

Finish:  Medium length, vanilla and spices.

Overall:  Very high quality, great balance, enjoyable and easy to drink.  This one is very polite, and is very refined and balanced - not overly complex.
