Cosmonauts grow barley on board the International Space Station, so Sapporo used it to make beer. It’s a very limited edition and won’t be available to the general public. 30 couples will be able to drink it via lottery.

The barley was grown as the result of an on-going crop growing project on board ISS, with other products including wheat, lettuce and peas. In the furute [sic], potatoes could also be grown in space.

However, Boris Morukov, a cosmonaut who spent 11 days in space on board the ISS, said: “I think we would try to grow potatoes as food, not for vodka production.”
