Altitude and pressure have always been two things stopping airline staff from providing the best food and drink on board. Now, however, KLM and Heineken have found a way to serve cold beer on tap while high in the sky.

As a result of reduced cabin air pressure, airlines have long struggled to serve draught beer on their flights. Lucikly for enthusiasts everywhere, KLM and Heineken have finally come together to engineer a very practical solution to the problem.

Although it is not the first time draught beer has been served on board, traditional drums and carbon dioxide cylinders cannot be used at high altitude since the low air pressure in the cabin creates excessive foam - not to anyone's liking!

To get around this problem, Heineken created a trolley to be pushed down the aisle, containing an air compressor and a container for the storage of beer.

Dutch airline KLM wants to install four kegs of beer that will stay cold for up to eight hours. Some tweaks have also been made to the diameter of the tap, with engineers promising beer just like that of your local watering hole.

The company is hoping to introduce the invention this July on long-haul, direct flights to Curaçao (the nation remains part of the Netherlands, positioned off the coast of Venezuela). The plan is to roll out the system across a series of KLM's flights.
