"Dr Bouby and his colleagues have now analysed the "macrobotanical" remains found at three sites during those digs: a paved floor near an oven and hearth of a home dated to the 5th Century BC, and a ceramic vessel and a pit that were near storage containers.
Ninety percent of the barley grains that were recovered from these locations had been induced to sprout.
The malted grains and the arrangement of the finds led the team to surmise a "home-brew" scenario, which they note requires no specialised equipment.
"All that is needed is an amount of grain, some water, containers (commonly pottery vessels) in which to soak the grain, a flat paved area - possibly the floor - to spread out and turn the grain during germination, an oven to dry it in order to stop germination, domestic grindstones to grind the malted grain, hearths and again containers for fermentation and storage," they wrote.
"Evidence for all of these sorts of equipment is reported from the Roquepertuse dwelling."
