Frequent Asked Questions

Q: Are any San-J products certified FODMAP Friendly?

Q: What is Tamari? What is the difference between Tamari and regular soy sauce?


Tamari is a premium Japanese soy sauce. 

The major difference between Tamari and regular soy sauce is the proportion of ingredients between soybeans and wheat. While regular soy sauce contains 40-60% wheat, San-J Gluten Free Tamari Soy Sauce is made with 100% soybeans and no wheat. While the sodium level of San-J Tamari and regular soy sauce is the same, the higher concentration of soybeans in San-J Tamari gives a richer, smoother, more complex taste than ordinary soy sauce.

Q: How is San-J Tamari brewed?


San-J Tamari is brewed and aged for up to six months using Japanese brewing methods handed down through eight generations.

Q: Is San-J soy sauce fermented?


Yes. San-J Tamari and Shoyu are fermented for up to six months. Only San-J’s fermentation process can create its rich, complex taste.

Q: Is San-J soy sauce pasteurized?


All San-J Tamari and Shoyu soy sauces are pasteurized. We do so to stop the fermentation process from continuing inside of each bottle of Tamari or Shoyu - otherwise, it could lead to off-flavors and harsh aromas and also create gases. We use the pasteurization method to maintain the best quality of our sauce as long as possible.

Q: Does San-J Tamari contain MSG?


We do not add MSG, but there could be some naturally occurring during the fermentation.

During fermentation, the protein in the soybeans is broken down to polypeptide chains and amino acids. The main amino acid we obtain is glutamic acid. Since the soybeans are fermented in a high salt brine solution, there could be some interaction of glutamic acid with sodium, creating some naturally occurring MSG (monosodium glutamate). Naturally occurring MSG can be found in many natural foods that have a rich flavor, such as cheese, mushrooms and tomatoes.
