Their argument is that Stone Age farmers were domesticating cereals not so much to fill their stomachs but to lighten their heads, by turning the grains into beer. That has been their take for more than 50 years, and now one archaeologist says the evidence is getting stronger.
Signs that people went to great lengths to obtain grains despite the hard work needed to make them edible, plus the knowledge that feasts were important community-building gatherings, support the idea that cereal grains were being turned into beer, said archaeologist Brian Hayden at Simon Fraser University in Canada.
Archaeological evidence suggests that until the Neolithic, cereals such as barley and rice constituted only a minor element of diets, most likely because they require so much labor to get anything edible from them — one typically has to gather, winnow, husk and grind them, all very time-consuming tasks.
However, sites in Syria suggest that people nevertheless went to unusual lengths at times just to procure cereal grains — up to 40 to 60 miles (60 to 100 km). One might speculate, Hayden said, that the labor associated with grains could have made them attractive in feasts in which guests would be offered foods that were difficult or expensive to prepare, and beer could have been a key reason to procure the grains used to make them.
"It's not that drinking and brewing by itself helped start cultivation, it's this context of feasts that links beer and the emergence of complex societies," Hayden said.
"In traditional feasts throughout the world, there are three ingredients that are almost universally present," he said. "One is meat. The second is some kind of cereal grain, at least in the Northern Hemisphere, in the form of breads or porridge or the like. The third is alcohol, and because you need surplus grain to put into it, as well as time and effort, it's produced almost only in traditional societies for special occasions to impress guests, make them happy, and alter their attitudes favorably toward hosts."
