The barley grain is the seed of the barley plant. It is a member of the grass family and is considered a cereal grain. There are two main classifications of domesticated barley, two-row and six-row. Two-row barley has a lower protein content but higher fermentable sugar content then six-row barley, but both are commonly used in brewing.
