The whisky, billed as the world’s first single malt Scotch to be finished in IPA craft beer casks, will be available at 85 Young’s sites across the capital.
It was previously available in the off-trade only.
Glenfiddich brand manager Sarah Harding said: “Since the Glenfiddich IPA Experiment launched in September 2016 in the off-trade, we have been overwhelmed by the interest from consumers and whisky connoisseurs nationwide due to the unique qualities of this experimental liquid.”
The experimental liquor has an ABV of 43% and was created by Glenfiddich’s malt master Brian Kinsman and Speyside craft brewer Seb Jones, who provided casks that had previously been used to hold Speyside IPA.
To celebrate the launch, Young’s will hold tasting events across its London estate, including an IPA masterclass at the White Bear, Kennington, south London, this evening (18 January) and a “Glenfiddich Deconstructed” event at the Dog & Fox, Wimbledon, south-west London, on 23 February.
Young’s director of marketing Gillian McLaren added: “We hope [the whisky] will appeal to our current whisky drinkers and look forward to educating more consumers on the wonderful world of whisky through our variety of consumer tasting events.”
It is unclear as to whether the whisky will be released into the wider on-trade.
