Wheat 'Durum Wheat' Overview
Durum wheat is similar to bread wheat except that the grains are larger and harder, it has a lower gluten content. Durum Wheat probably originated by natural mutation from Emmer wheat, which was the first wheat used by man. It is the hardest wheat, making it difficult to use for flour and rather it is milled into semolina and used for pastas and to make couscous. Red durum is mostly used for livestock feed.
