Barley Field is a Dwarfs infrastructure building in Total War: Warhammer. Dwarfen barley is a particularly hardy variety that can be grown on mountainsides and used to make beers and breads.
Background
Over time, Dwarfs have cultivated an especially tough variety of barley, the grains of which are either ground down into flour for use in baking stone bread, or malted as an essential ingredient in all manner of Dwarfish ales, beers and spirits.
