Beer on tap at 35,000ft

KLM ROYAL DUTCH AIRLINES is to serve beer on tap at 35,000 feet from next month. 

After years of development and experimentation with high altitudes and pressure changes, Heineken has found a way to have a draft beer — served from a keg rather than a bottle or a can — in the sky.

‘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 dispense only a huge amount of foam,’ Heineken’s Edwin Griffioen says. ‘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, as the keg of beer, the cooling system, and the air pressure compressor all had to fit in an airline catering trolley. In the end we had to leave out one of those pieces to make it all fit, so with pain in our hearts we had to leave the cooling behind.’

Miriam Kartman, KLM in-flight services vice president, commented: ‘We are always looking for typical Dutch products to set us apart from other companies. Customers rate beer from draught higher than out of a can.’
