KLM now serves Heineken draught beer on board planes
Heineken has become the first brewery to offer draught beer at 35,000 feet. The brewing company has partnered with KLM to offer the so-called "mile high pub", which is set to be trialled on intercontinental services in August. Heineken and KLM claim to have spent years developing a beer keg and dispenser that works at high altitude. "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," said Heineken. "We do have dispensers that work on air pressure, but these were too big to fit in a plane. It was one big jigsaw puzzle." That jigsaw puzzle isn't exactly complete: the cooling system that makes most pints icy cold had to be left behind because it was too big to fit inside the trolleys. <br/>
