How did beer lead to the development of cities in Mesopotamia and Egypt? Grains grew widespread in the Fertile Crescent (The crescent shaped area which had an ideal climate and soil for growing plants and raising livestock, it stretches from Egypt, up the Mediterranean coast to Turkey, and then down again to the border between Iraq and Iran.) causing the unintentional discovery of beer. The Fertile Crescent’s extremely rich soil was suitable for the growth of cereal grains after the last ice age, which occurred around 10,000 BCE. Hunter-gatherers were drawn to the cereal grains and, the ability to keep the grains for long periods of time stimulated them to stay. If they hunter-gatherers could thrive of off the wild grain if they were willing to stay near it and harvest at its peak. After the hunter-gatherers had spent so much time collecting the grain they would have been reluctant to leave the grain that they had collected nor could they travel with it. For this reason hunter-gatherers began to settle on the land. These settlers soon found that the grain could be stockpiled for long periods of time without spoiling. The technology of these settlers was still in development so storage spaces were not usually watertight, and when the water got into the stockpile of the collected grains they started to sprout and acquired a sweet taste. Thus becoming malted grains. When gruel, which is made of boiled malted grains, was left to sit for a couple of days it undertakes an interesting transformation. It becomes a pleasantly intoxicating and slightly bubbly liquid, as the yeasts from the gruel turn it to alcohol. The cereal grains used to make beer was often used as an eatable currency, because everyone needed it. People traded and sold it, causing the development and expansion of cities.…
