No, jau and jowar are not the same. Jowar, also known as sorghum, is a type of grain that belongs to the millet family. It is a white, rounded, small seed that is commonly consumed in parts of India. On the other hand, jau refers to barley, which is a different type of grain. Barley is similar in appearance to wheat before peeling off and has its own distinct characteristics and uses. While both jowar and jau are commonly consumed in India, they are distinct grains with different physical characteristics and culinary uses.
