What is Barley?
June 2016 - Barley's a kind of grass, like wheat, that is a good source of carbohydrates for people. Barley is different from wheat mainly in that it will grow with less rain, so you can grow it more different places, and also in that it doesn't taste as good as wheat. So poor people usually ate more barley, and rich people ate more wheat.
In the grasslands where people liked to live, barley grew wild, and people gathered it to eat boiled or ground into flour and baked when it came ripe every spring. People first began to farm barley (instead of picking it wild) around 11,000 BC in West Asia, possibly because of a climate change that made the world hotter and drier.
People ate barley like wheat as a boiled porridge, or in soup, and they also made barley bread. Barley is also the grain that people usually used to make beer. But people didn't make noodles out of barley.
Because you only ate the seeds from the barley, you had all the rest of the plant left over. The stalks dried into straw, and you could weave the straw into mats to sleep on, or give it to animals to sleep on, or make shoes or baskets out of it, or tie it into bunches to thatch your house. The leftover straw was nearly as useful as the seeds.
Barley spreads around the world
Barley farming spread south from West Asia to Egypt and North Africa around 8500 BC and to Sudan by about 5000 BC. Barley also spread to Greece and Italy about 7000 BC, and reached northern Europe about 5000 BC, travelling along the Danube and Volga rivers. Barley reached India by about 6000 BC, and got to China about 3000 BC. (People didn't eat much barley in China, where they ate millet or rice instead, but they seem to have used barley to make beer.) By about 1000 BC, people were farming barley in Korea, and by 500 AD Tibetan people were also eating a lot of barley. Barley reached Ethiopia about 500 BC, and West Africa in the Middle Ages. The Dutch brought barley to South Africa in the late 1650s.
Under Roman and Parthian rule, ordinary people lived mainly on barley bread and barley porridge and soup, while rich people ate wheat. But by the Middle Ages, poor people in Northern Europe and Eastern Europe switched to rye bread (not very happily). British settlers brought barley to the Americas in the 1600s AD in order to make beer, but they ate mostly wheat and oats. Spanish traders brought barley to South America, Mexico, and California, but it didn't really catch on. Their bigger contribution was to bring potatoes in the other direction, from South America to Europe, so that gradually poor people in Europe switched from barley to potatoes as their main food. Today Europeans and Americans mainly use barley for beer, but in North Africa and Tibet, barley porridge and barley bread are still ordinary food.
