When adventurer Ernest Shackleton set off to explore the South Pole in 1907, he didn't pack light. To keep warm (we presume), he brought along 25 crates of Charles Mackinlay & Co. whisky. Two cases were recently discovered, frozen on the bottom of the world for more than a century. In January, they'll be drilled out of the ice and now aficionados are lining up to get a taste.
