What it is

Barley is an annual cool-season grass in the Poaceae family, domesticated around 9000 BC in the Fertile Crescent. It produces edible kernels and is a major global grain crop, often described as the fourth largest cereal grain worldwide.

Why it matters

Barley is a key ingredient in beer and other malt beverages, and a large share of global production goes to livestock feed. It also appears in human foods like breads, soups, and stews. Canada is one of the world's leading producers, supporting domestic food systems and the brewing industry.

Key details

Barley grows in a wide range of climates, from sub-Arctic to subtropical regions. Major producers include Russia, Canada, and Germany. It is related to wheat, both being in the grass family. Common food forms include pearled and hulled barley.
