Soy sauce is NATURALLY BREWED from the basic ingredients of soybean, wheat, salt and water.
Wheat is roasted and grounded while the soy beans are steamed.
Mold starter is then mixed with the wheat and soybeans.

Matured Moromi is filtered to extract raw soy sauce.
The moromi residue or soy sauce cake is used for animal feed.
Raw soy sauce is heated to pasteurize.
Soy Sauce is then packaged.
That is all there is to it.
