malt, while pressed beer was a weaker, more watery brew that contained less grain. Mesopotamian brewers could also control the taste and color of their beer by adding different amounts of bappir, or beer-bread. To make bappir, sprouted barley was shaped into lumps, like small loaves, which were baked twice to produce a dark-brown, crunchy, unleavened bread that could be stored for years before being crumbled into the brewer's vat. Records indicate that bappir was kept in government storehouses and was only eaten during food shortages; it was not so much a foodstuff as a convenient way to store the raw material for making beer..
The Mesopotamian use of bread in brewing has led to much debate among archaeologists, some of whom have suggested that bread must therefore be an offshoot of beer making, while others have argued that bread came first and was subsequently used as an ingredient in beer. It seems most likely, however, that both bread and beer were derived from gruel. A thick gruel could be baked in the sun or on a hot stone to make flatbread; a thin gruel could be left to ferment into beer. The two were different sides of the same coin: Bread was solid beer, and beer was liquid bread.
Under the Influence of Beer?
Since writing had not been invented at the time, there are no written records to attest to the social and ritual importance of beer in the Fertile Crescent during the new stone age, or Neolithic period, between 9000 BCE and 4000 BCE. But much can be inferred from later records of the way beer was used by the first literate civilizations, the Sumerians of Mesojpotamia and the ancient Egyptians. Indeed, so enduring are the cultural traditions associated with beer that some of them survive to this day.
From the start, it seems that beer had an important function as a social drink. Sumerian depictions of beer from the third millennium BCE generally show two people drinking through straws from a shared vessel. By the Sumerian period, however, it was possible to filter the grains, chaff, and other debris from beer, and the advent of pottery meant it could just as easily have been served in individual cups. That beer drinkers are, nonetheless, so widely depicted using straws suggests that it was a ritual that persisted even when straws were no longer necessary.
The most likely explanation for this preference is that, unlike food, beverages can genuinely be shared. When several people drink beer from the same vessel, they are all consuming the same liquid; when cutting up a piece of meat, in contrast, some parts are usually deemed to be more desirable than others. As a result, sharing a drink with someone is a universal symbol of hospitality and friendship. It signals that the person offering the drink can be trusted, by demonstrating that it is not poisoned or otherwise unsuitable for consumption. The earliest beer, brewed in a primitive vessel in an era that predated the use of individual cups, would have to have been shared. Although it is no longer customary to offer visitors a straw through which to drink from a communal vat of beer, today tea or coffee may be offered from a shared pot, or a glass of wine or spirits from a shared bottle. And when drinking alcohol in a social setting, the clinking of glasses symbolically reunites the glasses into a single vessel of shared liquid. These are traditions with very ancient origins.
Just as ancient is the notion that drinks, and alcoholic drinks in particular, have supernatural properties. To Neolithic drinkers, beer's ability to intoxicate and induce a state of altered consciousness seemed magical. So, too, did the mysterious process of fermentation, which transformed ordinary gruel into beer. The obvious conclusion was that beer was a gift from the gods; accordingly, many cultures have myths that explain how the gods invented beer and then showed humankind how to make it. The Egyptians, for example, believed that beer was accidentally discovered by Osiris, the god
