This underground beer bunker keeps your beer cool without ice or electricity

Maybe you're sick of your Esky. Maybe you need a hiding place sticky fingers don't know about. Maybe you need to prepare for nuclear… never mind.

Maybe you don't need a reason at all to use the Biersafe Underground Beer Cooler – a nifty German invention that ensures 16 of your treasured brews are always chilled, without the use of ice or electricity.

All you need to do to enter this new-world utopia? Dig a hole. (Darryl Kerrigan would be proud.)

Made of cast iron, the beer cooler holds up to 16 bottles, which, after insertion in the cast iron tube, is insulated by the earth and kept cool.

And with an inbuilt bottle opener and zero-dollar electricity bill? It might be time to say goodbye to the beer fridge for good.
