Glenfiddich Anniversary Vintage, is described as one of the Speyside brand's “rarest whiskies ever released” and numbers only 286 bottles.
The whisky, which falls within the brand’s Glenfiddich Rare Collection and is priced at £699, has spent 25 years in a ex-sherry oak barrel.
It is available globally to "whisky connoisseurs and prestigious establishments".
Brian Kinsman, malt master at Glenfiddich said: “Bottled from just one European oak sherry cask and testament to the uniqueness of this exclusive whisky, Glenfiddich Anniversary Vintage has a cask-strength ABV of 55.2%.
“Glenfiddich has been family run since 1887 and with the freedom of independence and the foresight of long term planning, we have created the largest collection of single malt stock anywhere in the world. It allows to us to create exceptional and fantastic tasting whisky.”
Company director Peter Gordon said: “It was an honour to select this whisky. Born of two momentous anniversaries for our distillery, this whisky truly reflects the pioneering spirit that has underpinned our 125 year history and my great-great grandfather’s legacy of making ‘the best dram in the valley’.”
Glenfiddich is the world’s best selling single malt scotch, with 1.0m 9-litre case sales in 2012.
