Some researchers suggest that beer arose 11,500 years ago and drove the cultivation of grains. Because grains require so much work to produce (collecting tiny, mostly inedible parts, separating grain from chaff, and grinding into flour), making beer would have been reserved for feasts with important cultural purposes.

Those feasts — and alcohol-induced friendliness — may have enabled hunter-gatherers to bond with people in newly emerging villages, fueling the rise of civilization. At work parties, beer may have motivated people to put a little elbow grease into bigger projects such as building monuments.

“Production and consumption of alcoholic beverages is an important factor in feasts facilitating the cohesion of social groups, and in the case of [the Turkish site], in organizing collective work,” wrote Oliver Dietrich, a co-author of the Antiquity paper, in an e-mail. Dietrich is an archaeologist for the German Archaeological Institute.

The site in Cyprus includes a courtyard and hall, along with jugs, mortars, grinding tools and, crucially, several kilns that Crewe and her colleagues believe were used to toast barley for a primitive beer. To test their hypothesis, the team replicated the kilns to produce malted barley and used it in a cloudy and slightly weird-tasting beer, Crewe told LiveScience.

At the Turkish site, Neolithic hunter-gatherers worshiped deities through dancing and feasting at the temple site, which is filled with pillars carved with animal shapes and other cultic designs. The site also had what appears to be a primitive kitchen with limestone troughs that held up to 42 gallons of liquid. The troughs held traces of oxalates, which are produced during the fermentation of grain into alcohol.
