I was a little underwhelmed by the visitor's center here when I visited in May 2011, as it is Scotland's most popular single malt and one of my favorite whiskies of all time is a madeira cask finished Glenmorangie I had high expectations .  There was also a charge to take the tour, but you could get that credited if you bought a bottle.   The key feature of this distillery (and presumably it's whisky) are the tallest stills in Scotland (and they are tall) and the still house is very impressive and has to be seen.  It has been likened by others to a cathedral of distilling and I certainly get that analogy.  They also spent a good deal of time explaining Glenmorangie's current wood and maturation policy (and they no longer produce the madeira cask finish).    Compared to some of the other major brands such as Glenfiddich and The Glenlivet (and even Glenmorangie's sister distillery Ardbeg) I was left a little underwhelmed by the visitor experience but I understand that since my trip it has been revamped so perhaps it is better now.  Good.  I left with a bottle of the Quinta Ruban expression so I did get the cost of tour credited (and a nice key ring as well).
