Life in space is about to get a little tastier for Russia's cosmonauts.

The Russian Academy of Agricultural Science is developing a non-alcoholic beer, especially adapted for consumption in space, with added vitamins and minerals.

The scientists who developed the new drink had initially been asked to find a way of keeping up the spirits of those working in extreme conditions.

The non-alcoholic beer was originally devised for rescue workers who wanted a drink that would not impair their performance.

Tackling stress

Now, the science academy is working on an improved version to cheer up the cosmonauts.

The scientists claim beer is the ideal refreshment, as it is not only healthy but has been found to alleviate stress, even when it does not contain alcohol.

They are adding herbs and vitamins to the mix, to make it even healthier.

The beer will be served in special plastic cartons, to ensure that not a drop escapes.

However, it is unlikely that the American space agency (Nasa) will allow the cosmonauts to recreate that authentic pub atmosphere on the International Space Station.
