An ancient hexaploid species of hulled wheat possibly formed by the hybridisation of a tetraploid wheat such as emmer wheat and the wild goat-grass Aegilops tauschii or with bread wheat. It has less gluten than modern wheats and is popular for specialty bread making. It can be grown like bread wheat and is bst sown in autumn. The hulls can be threshed off in a garden shredder, although this damages the grain slightly.
