The world's most expensive bottle of whisky, a one-of-a-kind crystal Lalique decanter holding the oldest and rarest Macallan single malt ever (above), will be auctioned off by Sotheby's in New York on November 15 for an estimated $150,000 or more. The Macallan in Lalique Cire Perdue, which we previewed back in April, is filled with 64 years and older Macallan single malt Scotch, vatted together from three sherry seasoned Spanish oak casks. The famed Speyside distillery commissioned the legendary crystal artisan to create the decanter using the ancient "cire perdue" or "lost wax" method. Painstakingly hand crafted by Lalique exclusively for The Macallan, and inspired by the beauty of The Macallan's 150 hectare estate in north-eastern Scotland, it's based upon a ship's decanter of the 1820s. Proceeds from the historic sale will be donated to charity: water, a non-profit organization bringing clean and safe drinking water to people in developing nations.
