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: Are any artificial preservatives, flavors, or colors added to San-J products?

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.

Q: Are any San-J products certified Organic?

Q: Where do you get your soybeans from?

We will keep trying to use soybeans from United States or Canada whenever available but due to sourcing issues such as drought, soybeans from other countries may be used. Any soybeans used by San-J must meet our quality standards. These include testing for GMOs, heavy metals, protein content, size, moisture, as well as other testing. Documentation regarding the organic and non-gmo status of the soybeans must be obtained, and approved by our organic certifier and our non-gmo verifier.

Q: What is gluten?


Gluten refers to the proteins found in wheat, rye and barley. The consumption of gluten in these products adversely affects the health of those with celiac disease and gluten intolerance.

Q: What is celiac disease?


Celiac disease is a digestive and autoimmune disorder that is triggered by eating gluten. When gluten containing foods are consumed, damage occurs to the lining of the small intestine, making it difficult for the body to absorb nutrients. It is estimated that around 3 million or 1 out of every 133 people in the United States have celiac disease. There is no cure for celiac disease, but the condition can be managed with diet by removing all gluten containing foods.

Q: Who follows gluten free diets and what are the benefits?


For people with celiac disease, the only way to manage the condition is to follow a gluten-free diet. Through adherence to a gluten-free diet, the small intestine will begin to heal and the overall health of the affected individual should improve.

Gluten-free diets may also be followed by those who feel their overall health improves when avoiding gluten laden foods.

Q: How do San-J products fit into a gluten free diet?


Since most ordinary soy sauces contain around 50% wheat, they are typically off-limits for those following a gluten free diet. However, San-J Tamari Gluten Free Soy Sauce is naturally gluten free because it is made with 100% soybeans and no wheat, giving it a rich, smooth taste and making it ideal for those following a gluten free diet.
