Koji is fermented rice grain used to produce sake, rice wine, soy sauce and miso. It is made by inoculating steamed rice with Koji culture (Aspergillus Oryzae) and fermenting for a period of time.

Koji culture is considered a living food as it contains over 100 enzymes some of which breakdown starch and proteins, turning them into digestible glucose and amino acids which keep the culture alive.
