According to reports in The Sun the "trendy hipster pub" is serving Speedway Stout for five times the national average for a pint of beer.
The pub in Old Street, London, is part of the Craft Beer Co chain.
It more usually serves the stout in a third of a pint measure for £7.50 due to its hefty alcohol content of 12 per cent ABV.
The beer is made by the Californian-based Alesmith Brewing Company, which defends the high cost of the beer due its expensive ingredients such as Blue Mountain Coffee from Hawaii.
"When we import into the UK and showcase some extremely rare and unusual beers that tend to be incredibly high in ABV - they do come at a premium prices," Craft Beer Co MD Martin Hayes told the newspaper.
The beer is described by its brewer as, "ominous, pitch-black in appearance...Chocolate and roasted malts dominate the flavour, supported by notes of dark fruit, toffee, and caramel. A healthy dose of locally-roasted coffee from Ryan Bros. Coffee, Inc. added to each batch brings out the beer's dark chocolate flavours and enhances its drinkability. Despite its intensity, Speedway Stout's fine carbonation and creamy mouthfeel make it very smooth and surprisingly easy to drink. This beer ages very well and will continue to mature for many years to come."
Earlier this year it was reported that the average price of a pint of beer in London was £5.20 or £4.40 nationwide and a recent CAMRA survey confirmed that the majority of people think a pint in a pub is "unaffordable".
