"Common barley" refers to Hordeum vulgare, the most widely cultivated species of barley. It's used for food, animal feed, and brewing. Think of it as the 'workhorse' of the barley family. Unlike other grains like rice, barley is more tolerant of harsh conditions. It's a staple crop in many parts of the world, especially in regions with cooler climates. Common barley is a versatile and important agricultural product.
