There are all kinds of soy sauces

Soy sauce comes in many different varieties and there are many differences between soy sauces. For instance, the aroma, colour, consistency and flavour of the sauce shows whether it has been fermented or whether it is a non-brewed chemical synthetic. Kikkoman naturally brewed soy sauce is wonderfully aromatic, delicately savoury and enhances the primary flavours of all kinds of food without masking them. Non-brewed soy sauces have an artificial aroma and flavour, and overwhelm the dish if you add too many drops.
