'The World's Strongest Coffee' Is Not For The Faint-Hearted

It contains 80 times the caffeine in an average cup.

If you love nothing more than a strong cup of coffee, it may be time to book a holiday to Australia.

Viscous Cafe in Adelaide is serving a brew that’s been dubbed ‘the world’s strongest coffee’, which contains around 80 times the amount of caffeine found in a regular, single shot cup, according to The Adviser. 

The ‘Asskicker’ contains four espresso shots, 120ml of 10-day brewed coffee and eight 48-hour cold brew ice cubes.

Each ice cube is thought to contain the equivalent of two shots of espresso in caffeine. 

The café’s owner Steve Benington has advised that the drink should be consumed gradually over three to four hours, adding that it provides 12 to 18 hours of “sustained up-time”.

“Some people love it and some are broken by it but it’s all in the name of fun,” he told The Adviser. 

Benington said he originally created the drink for a tired nurse, who needed to stay awake for an impromptu 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 said.

Today, the beverage is served to customers with a clear health warning: “Persons with high blood pressure and/or heart conditions, drink at your own risk.” 

Commenting on the drink, Dr Helen Webberley, the dedicated GP for oxfordonlinepharmacy.co.uk, says it’s important to limit caffeine consumption.

“Caffeine is a stimulant and its effects vary from person to person,” she tells The Huffington Post UK.

“The main concerns with consuming higher and higher doses of caffeine, from a doctor’s perspective, would be in relation to the negative impact it would have on sleeplessness, nervousness, restlessness and irritability, all of which can affect mental health.”

She adds that caffeine also increases the heart rate and muscle tremors associated with this could be damaging.

“Our advice would always be to consume caffeine in moderation, and to question the reason why you need that stronger and stronger dose.”

Iced Coffee Around The World

Greece proves that there is a time and a place for instant coffee, and that it can in fact be absolutely delicious. The Greek frappe is traditionally made with instant coffee, water and milk, shaken and served over ice with sugar to taste. It's the perfect answer to sultry afternoons.

To make Japanese iced coffee, the coffee is brewed directly onto ice which means you can get it from cup to mouth even faster because there's no need to cool it first. Not only is this super efficient, it also creates a complex flavor that can't be achieved with cold brew.

Oliang, Thailand(03 of08)

Traditional Thai iced coffee is brewed with soybeans, sesame and corn. That's what gives it a special kick. (Though you'll commonly see it just brewed with cardamom, too.) It's served over iced with sweetened condensed milk -- another nice touch -- or evaporated milk with simple syrup. It basically tastes like heaven.

Vietnamese iced coffee is famous for its use of sweetened condensed milk, but that's not the only thing that makes it so memorable. Just like with Oliang from Thailand, Vietnamese coffee is interesting right from the start with the brewing process. Sometimes it is brewed with chicory and other times it's a mixture of Arabica and Robusta beans, which are notably harsh but blend well with the sweetness of the condensed milk.

This is not your every day iced coffee. Brazil's take on this beverage is... unique. There is coffee in it. And chocolate, lots of chocolate. But there's also cola -- which means double the caffeine -- served over ice with whipped cream.

This isn't exactly an iced coffee, but it is a beautiful, strong shot of espresso served on top of a scoop of vanilla ice cream. That's good enough for us. (And, ahem, that's Italian espresso and Italian ice cream, so... )

Italy might have the affogato, but Germany has the Eiskaffee. And if ordered at the right place, that eiskaffee will come in a tall glass full of strong, cold German coffee with a scoop of ice cream, grated chocolate, whipped cream AND a fancy wafer cookie. If you're really lucky, you get a party streamer too.
