The Macallan 1926 Fine and Rare 60 Year Old is one of only 14 of its kind in existence.

The whisky is expected to beat the current world record hammer price of £1.2 million, which is also a Macallan, BBC News reports.

The bottle leads the sale of the second half of one the world’s largest private whisky collections to go to auction. The ‘Perfect Collection’ was accumulated over decades by former US bottling magnate Richard Gooding, who died in 2014.

Iain McClune, founder of online auction site Whisky Auctioneer, said: “The 1926 has only been at auction once in recent years and at that time it broke the world record for the most expensive bottle of whisky ever sold, and we’re hoping that will happen again.

“The second part of the collection we expect to sell for several million pounds.

“We’ve got whisky dating back to 1921 - 100 years ago - and others from closed distilleries in Scotland that have rarely been seen before at auction.”
