When you’re over 35,000 feet above ground level there is a high probability of running out of things to do. While this doesn’t apply to those who love snatching 40 winks while they fly, others could do with something to occupy themselves with. How about some cool beer for starters? Unfortunately, serving beer at a high altitude is impossible for many airlines but Dutch cruiser, KLM, has found a great way to get around this problem. They have partnered with Heineken to serve beer on tap.
This has been made possible with a special ‘brew lock’ keg that doesn’t affect the taste or form of the beer when served at an altitude. The special keg is the fruit of years of research and leverages cabin pressure instead of carbon dioxide. Edwin Griffioen from Heineken said, “Because the air pressure is so much lower in an airplane than at sea level, a traditional beer tap will not work as it will only dispense a huge amount of foam.” The contraption is said to be 3D-printed and is rolled around on a trolley.
All the draught beer made available through this novel technique will be brewed at the Zoeterwoude brewery in Holland. The servings will commence on selected airlines at first and will be executed from August.
