Sunk Punk is a 7.1% abv brew containing maritime-themed ingredients such as buckweed, distilled sea salt and rum.
The beer was produced in a fermentation tank lowered to the sea floor off the Scottish coast earlier in the summer.
Brewdog co-founder James Watt said the beer had been produced in an attempt to lift an ancient witch’s curse on a fisherman said to be the cause of storms on the Scottish shoreline.
Watt said: “This is history in a glass. This is human achievement. This is science meets superstition. This is the latest marketing gimmick from Brewdog.”
The beer is a limited edition of 960 bottles which are selling on the brewery’s website for £9.99 each.
