Extremely vain and very settled on the sour side of the spectrum. Nutty-fermented sherry notes. Rather sultanas as raisins. Juicy, sparkling, astringent. Despite the massive role played by the finish here, I got the impression that the Glenallachie character (as Billy Walker is trying to shape it) still has something on it, because among all the forest fruit juiciness there is always a kräutrige, Almost vegetable note (rosemary and artichokes?), which I found in the 12er the most interesting aspect. In addition, I would strongly suspect that even this bottling virgin oak has seen: from about the middle of the flavor development is a pretty violent spiciness, which suggests that some very fresh (or even virgin) barrels with Vatting flowed.
Positively seen: a strong sherrylastiger Malt, which nevertheless does not come to set or even superimposed comes along and offers an interesting balance of acid, spice and spirit.
On the negative side: a malt that seems to be more "assembled" than harmoniously matured, and in whose price range and drum composition I would always prefer the current Glendronach 15.
