Beer in space: A short but frothy history

Beer has been a part of human history since the beginning, so it's no surprise that it will be coming with us across the final frontier.




Graduate student Kirsten Sterrett at the University of Colorado in the US wrote a thesis on fermentation in space, with support from US beer behemoth Coors. She sent a miniature brewing kit into orbit aboard a space shuttle several years ago and produced a few sips of beer. She later sampled the space brew, but because of chemicals in and near it from her analysis, it didn't taste great by the time she tried it.


Beyond the challenge of producing beer in space is the problem of serving it, says Jonathan Clark, a former flight surgeon and now the space medicine liaison for the National Space Biomedical Research Institute in Houston, Texas, US.


Without gravity, bubbles don't rise, so "obviously the foam isn't going to come to a head", Clark told New Scientist.


The answer, Dutch researchers suggested in 2000, is to store beer in a flexible membrane inside a barrel. Air can be pumped between the barrel and the membrane, forcing the beer out of a tap. Astronauts could then use straws to suck up blobs of beer.
