Both barley (jau) and millet (jowar) are consumed in parts of India, but they are different grains with distinct characteristics. Barley is often used in brewing beer, making bread, and as animal feed. It is also highly nutritious, containing vitamins, minerals, and fiber.

Jowar is often ground into flour and used to make rotis (flatbreads), dosas, or porridge. It is also used as animal feed and in the production of ethanol.
In summary, jau (barley) and jowar (millet) are two different types of grains with distinct characteristics and culinary uses.
