Personally, I have given it a lot of opportunity, and it doesn't do it for me. Not a big deal. As for the Lagavulin 16, I had a bottle of that and remember tasting it after having sat aside for a bit. I was blown away by how great it was. And the Glenkinchie - also very nice. A lot more delicate than the Lagavulin for sure! Both were great.
Looks like you are making your way around Diageo nicely. Is Dalwhinnie next for you, by chance???
