I just had my first few glasses of this over the weekend and wanted to share my thoughts (note that my bottle is from 2017):
On the nose, I only really got two things: brandy and caramel. Both very strong and bombastic, but in a good, enticing way, and very balanced. But it really did smell more like a brandy than a whisky.
The taste is certainly like a whisky, though. It's heavier and oilier than a normal whisky, but again, in a good way. It's very smooth and sweet, with no burn at all. The caramel/marzipan is strong at first, with the wood flavours coming through more in the finish. It is very easy and pleasant to drink. I would almost call it a desert whisky.
I know it's fairly expensive (even here in Taiwan), but if you like sherry-matured whiskys you'll definitely like this.
This bottling comes from the same casks as the Kavalan Soloist range, which are all around 54% ABV, diluted down with mountain water to 46%. So in a sense, if you just buy this bottle, you're getting the exact same thing as the Soloist range, but for cheaper, and with the water already added for you (unless you like to drink a cask-strength without adding your own water).
