The difference between brewed and non-brewed soy sauce go far beyond production methods. Brewed soy sauce has almost 300 identifiable constituents amongst ingredients in food products.

These work together to create flavour and aroma (a few listed in the accompanying table). They are the direct result of several reactions that take place concurrently during fermentation.

Kikkoman has over three centuries of experience brewing soy sauce the natural way, with only water, soybeans, wheat and salt. With that expertise comes a rich heritage of uncompromising dedication to quality and tradition.
