Marc Newson, speaking to Dezeen:

The obvious and easy analogy would be Nespresso.

It looks just like a Mac Pro turned on its side with a tap on the end. I need one of these.

Dezeen explains how the unit works:

It can be filled with pressurised modules that hold two litres of beer, called Torps, that can be ordered to contain a number of different types of brew from Heineken's collection of brands. These are inserted horizontally into a circular compartment in the centre of the machine. A handle on the front twists to open and re-seal the device.
