I am currently debating on a purchase to add a bottle to my collection. The two contenders, as the title suggest, are Ardbeg 17yo and Ardbeg 1977. They are both reasonably priced with the '77 being about $100 dollars more. I am wondering what you guys think about these two expressions of Ardbeg. Which one is more available/or rare? For you collectors, which one do you find to be more collectable or more likely to appreciate in value (I will eventually drink it although it might sit in my collection for a few years)?
Thanks for your input.
