Was initially quite underwhelmed with the 17, until more drinking of the 12 showed a very nut heavy flavor profile, whereas the additional 5 years adds just a slight fruity and sherried edge to the dram, almost makes you forget the 12 was Sherry aged too since it’s not as notable as, say, the Macallan 12. The 17 really does jump to a new level after 5 years, but I’m still not quite sure it’s worth twice the price of the 12. Regardless, this is a really rich dram, worth a glass if you can snatch it, but only grab a bottle for special occasions
