This thread led to a Scotch odessey for my son & I. Prior to it, scotch wasn't on my adult beverage radar screen. So thanks to all for the impetus & the lightening of our wallets (grin)!
I now own approx. 15 single malts. And my son, owns more, including some Irish. In fact, he just sent me the following in an e-mail:

I have procured a bottle of "Shackelton's Whiskey" (http://www.thewhiskyexchange.com/shackletons-whisky-mackinlays-rare-old-highland-malt/) which is a vatted malt replica of a 100+ year old Scotch whisky that was found buried in the ice of Antarctica underneath one of the huts that Ernest Shackleton's team used during their "Nimrod" expedition of that land (http://en.wikipedia.org/wiki/Nimrod_Expedition).
The discovery and eventual return of some of the original whiskey to Scotland is an interesting story in and of it self. You can start here: http://www.whyteandmackay.co.uk/blog/2011-01-19-shackletons-whisky-unboxed-video-pictures-faq.aspx and here http://www.thehistoryblog.com/archives/13376.
Ultimately the original whiskey was sampled and painstakingly analyzed for scientific and industry curiosity as well as to enable the possibility of replicating it. The scholarly paper detailing the results can be found here: http://www.scientificsocieties.org/jib/papers/2011/G-2011-0630-1168.pdf.

I'm looking forward to the Shackelton tasting that my son is planning with me, his best friend & my nephew.
