Kernza® grain is harvested from intermediate wheatgrass (Thinopyrum intermedium). This (cousin) of annual wheat has been grown throughout the USA to provide fodder for livestock. Now intermediate wheatgrass is being domesticated as a grain for human food.
Intermediate wheatgrass can be grown as a “multi-functional” crop, yielding various commodities as well as ecosystem services. Kernza® grain is a perennial substitute for annual wheat in foods like baked goods and beer or can be used as a whole grain like barley or rice.
