Barley is a grain that's related to the grass family and is used in many foods and drinks. Barley is used all over the world and is most commonly found in breads, breakfast cereals, soups, and stews.
Barley is the fourth largest crop grown in the world. It's used to feed grazing livestock, eaten as a whole grain, milled into flour for baking, and dried to make malt, an ingredient in both beer and whisky. The Old English root of barley is bærlic, most likely from a Proto-Indo-European source that means "bristle, point, or projection."
