Young, high-proof Glengoyne often makes me sad, as it reminds me of how good this stuff is at a higher age (and lower ABV).
Richly sherried and rather sweet, but the high ABV covers over the aromas. With more time and/or water, you find marzipan / almond paste, cookie dough, gingerbread, and pretty high-quality American oak (nothing fresh or spicy, rather a cask whose active, young edges have already been sanded off by previous fillings).
Yup, that's PX alright. Syrupy-sweet, with big notes of cherry-flavored herbal cough drops, raisins, and red wine gums. You have to be quick to catch the flavors, because in the last third, the barely-teenaged spirit takes over and drowns the aromas in alcoholic heat. When you add enough water to make the whole cask-strength shabang meaningless, you are rewarded with some intriguingly intense, mango-like fruit flavors. I guess it's well executed as far as this style goes, but sorry, it's just not my jam.
(Artificial) cocktail cherry, raspberry jam, pickled ginger. Still some heat, even with water.
