No. Barley is not wheat at all. Barley and wheat are two different species of cereal grasses belonging to the family Triticeae. Barley does belong in the wheat family, which is, as mentioned, Triticeae, but is of an entirely different species from wheat. The species name for barley is Hordeum vulgare, and the species name for wheat is Triticum aestivum. No doubt either look similar, but both are quite different from the other.
Forms of Barley Nutrition. Barley Grass is the seedling of the barley plant. This grass is usually harvested about 200 days after germination, while the shoots are not even a foot tall. People consume it in this form because the young leaves are rich in minerals, vitamins, antioxidants and amino acids.
