Kikkoman Soy Sauce Dispenser in 5fl oz (148ml) bottle. Kikkoman is naturally brewed and aged for full flavor, just like a great wine. We start with the finest soybeans and wheat. We blend them with a starter culture, water and salt. And then we add the most important ingredient of all: time. Despite the advances of technology, our fermentation process simply cant be hurried. It takes several months for the rich, mellow flavor and the complex bouquet of Kikkoman Soy Sauce to develop.
