The sale price far exceded the pre-auction estimate of up to £26,000.

Just Whisky director Graham Crane said the results demonstrated that there remains strong demand for exceptional whiskies.

A bottle of The Macallan 72 Year Old in Lalique fetched £90,750, the highest price achieved in the latest monthly auction. The seller had acquired the bottle for $60,000 last year (worth around £45,800 at the time of the deal).

Sales of malt have boomed in overseas markets such as China in recent years. The emergence of a new class of affluent consumers has stoked demand for goods seen as prestigious.

Overseas buyers have acquired whisky producers such as the BenRiach Distillery Company.

Loch Lomond Distillers is targeting expansion in the Chinese market after it was acquired by a major Asian investment firm, Hillhouse Capital, earlier this year.

The whisky firm has made progress in markets such as Vietnam and Cambodia.
