A RARE “forgotten” cask of whisky, bought for £5000 30 years ago, is expected to set a world record when sold.

The 374-litre cask, filled on May 5, 1988, has been held in bond at the Macallan Distillery in Moray for almost 34 years.

It was bought on a whim by an expat who then forgot about it until they were reminded by Macallan that it was still maturing in the warehouse.

Bids for the rare cask have already reached $170,000 (£130,000) since the auction went live at 7pm on Friday and are expected to soar before the sale on the Whisky Hammer website ends on Sunday.

It is expected to break the $574,000 (£439,000) record set in 2021 for the sale of a 30-year-old re-racked Sherry hogshead from Macallan.

Daniel Milne, co-founder of Whisky Hammer, said: “Casks of this age and size are extremely rare, especially from The Macallan.”
