Lokwan Wheatis a major cereal grain, commonly found in bread, beverages, and various cuisines of every culture. It was one of the first cultivated grains in history and, to this day, remains one of the most widely used grain. The most important thing to know about barley is that it comes in two basic forms: hulled and pearl.
