The event took place on January 18, 2014, organized by Sotheby's. The 6-liter bottle of Macallan Decanter "M" whiskey, a 64-year-old single malt broke the record and became the world's most expensive whiskey.

To get a sense, this represents €77,130 per liter, or €3,085 a 40 ml glass.

A very high price can be explained by both the contents and the container. The Scottish distillery Macallan has partnered with Lalique to create this 6 liter bottle, which is the largest ever made and weighs 11.3 kilograms empty. The bottle being sold is one of four exclusive bottles published, all of which bear the name of a Roman emperor (Constantine).

There were 17 craftsmen who worked on the label, including two Frenchmen who were "best workers in France," with a total of 50 hours of work for each bottle. The identity of the buyer is unknown and we only know that he is Asian. But Sotheby's said that the money would be donated "to charities in Hong Kong."
