Researchers working in the Antarctic have recovered five crates of whisky and two crates of brandy belonging to polar explorer Ernest Shackleton, who tried to reach the South Pole in the early twentieth century. The bottles have been embedded in ice for over a century. Anchor Marco Werman speaks with Richard Paterson, Master Blender at Whyte and Mackay, the company that supplied the booze for Shackleton’s polar cruise.
