What is head of barley?

The head of barley refers to the flowering part of the barley plant, specifically the spike that contains the grains. Each spike is made up of multiple spikelets, which house the individual grains or seeds. Barley heads are harvested for various uses, including animal feed, brewing beer, and producing food products.
