An exclusive whisky priced at around £2,000 per bottle goes on sale this week.
At just under 40 years old, the single malt is the rarest ever released from its distillery on the Scottish island of Islay.
Only 261 bottles of Ardbeg 1965 are going on sale, of which 100 will be released to UK retailers.
It comes in a hand-blown glass bottle which comes with a numbered wax seal to prove its authenticity.
The bottle itself contains a sprinkling of Islay sand in its glass.
Despite its price tag, the 41.3 per cent ABV drink is likely to attract a high level of interest from whisky lovers, according to Harrods food spokesman Andre Dang.
"There is a demand for it simply because there are a number of connoisseurs who love collecting something very rare and very prestigious - and then there are the people who actually drink it. This will probably be extremely popular," he said.
The most expensive 40-year-old whisky currently on sale at Harrods is priced at £1,400.
But the Ardbeg 1965 is not the most expensive single malt ever to hit the market. Previous whiskies aged 40 years plus have retailed for £4,000 and above. The Scotch Whisky Association's director of consumer affairs Campbell Evans said the Ardbeg 1965 would be sought-after by whisky enthusiasts.
"The person buying this would expect a smoky whisky with the aroma of the sea and saltiness coming through it," he said.
The Ardbeg 1965 will be available at Harrods, Selfridges, Harvey Nichols and other selected stores.
