I really like the comparison - made by Ruben from Whiskynotes - of this to the Lagavulin Distiller's Edition. There's a similar sense of enhancing sweetness and tamping down peat smoke without losing the core identity of the distillate. This is still medicinal, peppery, salty, and complex, but it tones down the sheer herbal intensity of the Quarter Cask (to say nothing of the 10 CS), augmenting it with dry, yet fruity Oloroso notes. This definitely plays in a league with the aforementioned Lagavulin DE and Ardbeg Uigededail, yet it clocks in at roughly half the price.
In short: I love it, and the only thing that keeps this bottle from reaching a higher mark is a certain (but slight) lack of depth / age.
