The Macallan 1926 60-year-old single malt was expected to sell for between £350000 and £450000.
The previous auction record for a single bottle of Scotch was £1.2m, set by another Macallan bottle from the same cask in November last year. Sotheby’s described The Macallan 1926 from Cask Number 263 as the “holy grail” of whisky.
The Macallan distillery is in Craigellachie, Moray, in Scotland. It is reputed to be the world’s third largest-selling single malt, behind Glenfiddich and Glenlivet.
