A controversial brewery has claimed to have snatched the world's strongest beer title from its German rivals - with a 41% volume ale.
Scottish firm BrewDog said its new creation, named Sink The Bismarck!, "takes beer to a whole new level".
The launch of the record-strength IPA comes weeks after German brewer Schorschbrau appeared to take the strongest beer title with its 40% strength Schorschbock.
BrewDog, of Fraserburgh, Aberdeenshire, said its newly-unveiled Sink The Bismarck! costs £40 for a 330ml bottle and will only be sold via its website.
The company said the beer, which is stronger than whisky and vodka, should be consumed in spirit-sized measures.
Managing director James Watt said: "In true BrewDog fashion we've torn up convention, blurred distinctions and pushed brewing to its limits with this audacious amplified ale."
The firm drew criticism from industry watchdog the Portman Group last year when it unveiled a 32% beer, Tactical Nuclear Penguin.
It has also faced claims that its 18.2% Tokyo beer promoted excess.
But Mr Watt said the brewery was doing all it could to promote a "new and responsible approach" to beer drinking.
He said: "We want the public to learn to understand, appreciate and respect beer. At BrewDog we want to highlight a different approach to beer - one which focuses on quality ingredients and craftsmanship, and not marketing budgets and volume sales and binge consumption."
