Brewgooder has partnered up with Bruichladdich and Vault City to create a whisky sour beer which will be auctioned for charity.
The collaborative brew is hoped to become one of the most expensive bottles of beer sold at auction - and it is hoped the lot will fetch more than £1,000.
Proceeds will go towards supporting clean water charity projects with Charity Water.
The first four bottles from the project, which were hand sampled, labelled and signed by Vault City's head brewer Ravi Bos, will be auctioned by Whisky Auctioneer.
The 11% alcohol by volume (ABV) brew has been aged for nine months in Bruichladdich casks prior to bottling.
This collaboration also marks the first time that the classic Laddie casks have left Islay, to be used for beer maturation as part of a joint project directly between distillery and brewery.
Brewgooder's Billion Pint Pledge is on track to deliver 150 million litres of clean water by the end of 2022.
The auction will take place from 28 January to 7 February and along with securing the whisky sour beer, the highest bidder will gain exclusive access to the Vault City brewery and taproom, as well as other extras, including a tour and tank tasting session led by the company’s co-founder and head brewer.
Alan Mahon, founder at Brewgooder, said: "This beer is not only innovative, unique and delicious, it also has the potential at auction to be the most impactful beer ever made for a good cause, producing literally thousands of litres of water for those who need it."
Joe Wilson, head curator at Whisky Auctioneer, said: “This is the first time that Bruichladdich casks have been used in a direct partnership with a brewery, making this not only an unprecedented collaboration for the distillery, but an exciting opportunity for Islay whisky fans and beer enthusiasts to support a huge number of people who do not have access to clean and safe water.”
