Once opened, the soy sauce will start to lose its freshness and the flavor will begin to change. By refrigerating the sauce, the flavor and quality will remain at their peak for a longer period. As long as no water or other ingredients have been added to the soy sauce, it would not spoil if it had not been refrigerated.

Kikkoman Soy Sauces contain greater than 2% alcohol by volume. The alcohol is a result of the fermentation process.  Like wine or beer, our soy sauces are brewed and they are made from wheat, soybeans, salt and water. During fermentation, the wheat starches are broken down to sugars and part of the sugar is changed into alcohol.

The all-purpose Kikkoman Soy Sauce and the Kikkoman Less Sodium Soy Sauce are brewed at the Kikkoman Foods, Inc. plant in Walworth, WI where there are no peanuts or tree nuts ingredients used. Please check the back of your label to see where the product was made.

Our tabletop dispenser was first introduced in Japan in 1961 and it is now recognized worldwide as an iconic symbol for Kikkoman Soy Sauce. The dispenser bottle was designed by Kenji Ekuan, a well-known industrial designer. In 2005, the dispenser was added to New York’s Museum of Modern Art Collection. To learn more about our dispenser, please click here. To open the dispenser bottle, first remove the outer plastic seal and cap from the bottle. Then, remove the plastic insert from either inside of the cap or on top of the bottle and screw the cap back on. If you have difficulty twisting off the cap, we suggest running the unopened bottle under hot water for a minute and then use a rubber gripper or a wet cloth to carefully twist off the cap.

For our sauces, the Best By Date is printed on the neck of the glass bottle or the bottle cap. Our seasoning mixes and gold-colored packaged soup mixes have a date printed across the top of the package back or embossed on the side of the packets. Please click to here view some examples.  

For the best quality, we recommend using the sauces within one month of opening.
