Introducing the new San-J Tamari Gluten Free Soy Sauce. Previously San-J Premium Tamari Soy Sauce (Black Label), which used to contain a very small amount of wheat, has been reformulated to be completely gluten-free while maintaining the same rich, robust taste people have enjoyed for years. Look for the certified gluten-free logo on the label. Our natural fermentation process gives San-J Tamari great flavor enhancing properties. Add tamari to soups, gravies, sauces, and casseroles. Use it as a marinade and in stir-fry dishes.
