Bottle of 'Holy Grail of whisky', 60-year-old The Macallan Valerio Adami 1926, sells for £848,750 at auction

You could buy a lot with £848,750: a mansion, several Maseratis, a yacht, or should you wish, this bottle of whisky.

In a record-breaking sale, the bottle of the world's most expensive whisky fetched a hammer price of £700,000 plus a buyer's premium of £148,750 in the auction at Bonhams in Edinburgh on Wednesday.

The 60-year-old bottle of The Macallan Valerio Adami 1926 - described as 'the Holy Grail of whisky' - attracted attention from some of the world's most serious collectors, particularly in China, and had been estimated to fetch up to £900,000.

The high sale price means that each ml in the 75cl bottle is worth £1,131.67, while a dram (a 25ml measure) would cost an eye-watering £28,291.67.

However, it is thought the unknown buyer, who made the purchase via phone, will keep the tipple as a collector's item.

Martin Green, Bonhams whisky specialist in Edinburgh, said he was "delighted at this exceptional result.

"It is a great honour to have established a new world record, and particularly exciting to have done so here in Scotland, the home of whisky.

"The Macallan 1926 60-year-old has been described as the Holy Grail of whisky.

"Its exceptional rarity and quality puts it in a league of its own, and the world's most serious whisky collectors will wait patiently for many years for a bottle to come on to the market."

The whisky is officially described as a 60-year-old, having been created in 1926 and bottled in 1986.

Bonhams said the bottle was presented in a specially commissioned cabinet, or tantalus, based on a traditional brass and glass distillery spirit safe.

It was bought by the seller direct from the Macallan distillery for an undisclosed sum in 1994.

Bonhams said the previous world record was set by the auction house in May this year when another bottle of The Macallan Valerio Adami 1926 was sold for £814,081.

Macallan commissioned two Pop Artists - Valerio Adami and Peter Blake - to design labels for a very limited edition of 24 bottles. Twelve carried the Adami label and 12 had the Blake design.

It is not known how many Adami bottles still exist.

One is said to have been destroyed in an earthquake in Japan in 2011, and it is believed at least one of them was opened and drunk.

The bottle sold on Wednesday was bought by the seller direct from the Macallan distillery for an undisclosed sum in 1994.

In May, Bonhams Hong Kong sold a bottle of The Macallan Peter Blake 1926 60-year-old for £751,703.
