“Asskicker” Coffee Contains 80 Times More Caffeine Than Regular Brew, Comes with a Health Warning

Viscous Coffee, a café in Adelaide, Australia, sells a cup of super-coffee that contains five grams of caffeine – 80 times more than a normal cup of java and half the dose considered to be lethal. Called the “Asskicker”, the strong beverage comes with a health warning for people with heart problems and blood pressure issues.

A cup of espresso has about 60mg of caffeine, while a serving of standard filtered coffee has about 150mg of it, depending on how it is prepared. The Asskicker contains five full grams of caffeine, which Viscous Coffee owner Steve Benington says is enough to provide 12 to 18 hours of “sustained up-time”. But the high caffeine content means it shouldn’t be consumed in one go, but slowly, over a period of four hours.

Benington says he came up with the idea for the Asskicker when an emergency department nurse asked him for something that would keep her awake and alert for an unexpected night shift. “She consumed her drink over two days and it kept her up for almost three days — I toned it down a little after that and the Asskicker was born,” he recalls. Nowadays, the complex concoction is made with four espresso shots, four 48-hour brewed cold drip ice cubes, 120ml of 10-day brewed cold drip and is finished with four more 48-hour brewed cold drip ice cubes. “Each cold drip ice cube is approximately equivalent of a bit more than two shots of espresso in caffeine,” Benington explains.
