Brewdog is hoping to hit the record books with the launch of what it claims is the world's strongest beer.
At 32% abv, the Scottish brewer's Tactical Nuclear Penguin beats the previous record held by German brand Schorschbraer by 1%.
Just 500 bottles will be available from brewdog.com and select beer specialists including UTO Beer in London and Cornelius Wines & Spirits in Edinburgh.
The brew began life as a 10% abv imperial stout 18 months ago. It was then aged for eight months in an Isle of Arran whisky cask and eight months in an Islay cask.
The final stages involved storing the beer at -20 degrees for three weeks to get it to 32% abv.
The beer comes packaged in a brown paper bag with a hand-drawn penguin on it.
A spokeswoman said: “Half the bottles will be priced at £30 with the other 250 priced at £250 – this will include a share in the brewery as part of the brand's Equity for Punks campaign.”
The campaign is looking to raise £2.3 million to build a new eco-friendly, carbon neutral brewery in Aberdeen.
