Upon opening (on the palate): Big sherry...huge flavor. Orange infused dark chocolate, dried pasilla-ancho chilies, cinnamon...in the background, I found a glorified granola bar, overripe sugary dates, and golden raisins. It's slightly woody but not offensive-- everything came together nicely while aging. Enormous influence from the sherry. (Nose matches the palate well, no surprises there).
About 30 days after opening: dried pasilla-ancho chilies are dominating everything else...if you haven't had that variety, it could also be closely compared to the more common Mexican entero pepper...both are extremely earthy peppers which have a lot of dark; spicy fruitiness to them similar to dates and raisins-- but this is decidedly peppery. I absolutely love chilies but am not really liking how dominant it is here...but I will give it an unbiased score: for an eighteen year old single malt, 83 points. Not my favorite sherry bomb, but it's a massive one, and packed full of flavor-- very, very big whisky! Extra points for the impressively thick, syrupy, velvety mouthfeel, and for the high concentration of flavor per drop...truly impressive.
