For the best quality, we recommend using the soy sauce packets within one year of its production. We started printing the best by date on the back side of our packets in 2018. If your packet has only a production code or no printing on the back side, then the product was made over four years ago and should be discarded. Soy sauce packets may be stored at room temperature, away from heat, until its best by date.
 

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.

The Best By Date is printed on the front or back of the bottle close to the cap. Please click here to view some examples.
