The Kikkoman Standard: Naturally Brewed
Kikkoman's traditional, naturally brewed soy sauce is famously made with a simple and transparent list of ingredients: water, soybeans, wheat, and salt. This core product is crafted using a centuries-old fermentation process that takes several months, resulting in its complex flavor profile. Unlike some other soy sauce brands that rely on artificial enhancements to speed up production, Kikkoman’s standard variety eschews additives like artificial colors, flavors, and preservatives. The natural fermentation creates a rich umami flavor, appealing color, and complex aroma without any shortcuts.
The brewing process itself is an art form. The soybeans and wheat are combined with a special fungus, Aspergillus, to create a fermented mash called koji. Over several months, the enzymes from the koji and other microorganisms break down the proteins and starches into amino acids, sugars, and organic acids. This biological transformation is responsible for the deep, savory umami taste, the reddish-brown color, and the aromatic properties that characterize quality, naturally brewed soy sauce. It is a stark contrast to chemically produced soy sauces, which are made in a matter of days by hydrolyzing soybeans with strong acids, and which often require additional additives to mimic the flavor and color of naturally brewed sauce.
The Role of Each Ingredient
- Water: The base for all the other ingredients, crucial for the fermentation process.
- Soybeans: The protein-rich element that is fermented to produce amino acids, which are the source of the umami taste. Kikkoman guarantees its soybeans are non-GMO.
- Wheat: Provides carbohydrates that are broken down into sugars, contributing to the soy sauce's sweetness and aroma. The roasting of the wheat also plays a part in the overall flavor profile.
- Salt: Controls the fermentation by preventing unwanted bacterial growth and acts as a preservative, extending the shelf life naturally.
Variations and the Additive Question
While the classic Kikkoman Naturally Brewed Soy Sauce contains no artificial additives, it's essential to check the labels for other products in their lineup, as some specific variations do include a preservative. For example, Kikkoman's foodservice-specific regular soy sauce sold in the US market lists "sodium benzoate: less than 1/10 of 1% as a preservative". Similarly, other specialty products might have specific ingredients added to achieve a desired flavor profile, such as the sweet soy sauce which includes sugar and vinegar.
Comparison of Kikkoman Varieties

| Organic Soy Sauce | Water, Organic Soybeans, Organic Wheat, Salt | No artificial additives | Retail (Organic) | Certified organic, GMO-free |
| Less Salt Soy Sauce | Water, Soybeans, Wheat, Salt, etc. | No artificial additives mentioned | Retail (Health-Conscious) | 43% less salt than standard |
| Sweet Soy Sauce | Water, Sugar, Soybeans, Wheat, Salt, etc. | Sugar, spirit vinegar | Specific Cuisine | Mild, sweet flavor |
| Regular Soy Sauce (Foodservice) | Water, Soybeans, Wheat, Salt, Sodium Benzoate | Sodium Benzoate | Foodservice/Institutional | Stabilized for bulk use |
Natural vs. Chemically Produced Soy Sauce
Understanding the distinction between naturally brewed and chemically produced soy sauce is key to discerning the quality of your product. Naturally brewed sauce, like Kikkoman's standard offering, undergoes a lengthy fermentation process that creates flavor components naturally. Chemically produced soy sauce, sometimes labeled as 'hydrolyzed soy protein,' is a cheaper alternative made by breaking down soy protein with hydrochloric acid. These products are not aged and often require the addition of artificial colors, flavors, and other additives to replicate the taste of true soy sauce. For a more authentic and cleaner-tasting experience, naturally brewed is the superior choice.
A Note on Sodium Benzoate
Sodium benzoate is a common food preservative used to prevent the growth of mold, yeast, and bacteria, especially in acidic foods like soy sauce. Its presence in some Kikkoman products, particularly those designed for foodservice, is typically for extended shelf life and stability, as these versions may be handled differently than retail products. While it is a common food additive and generally recognized as safe (GRAS) by regulatory bodies, its inclusion is a departure from the strict no-additive claim of the core naturally brewed product.
Conclusion: Does Kikkoman Soy Sauce Have Additives?
In conclusion, the answer depends entirely on the specific Kikkoman product. The flagship "Naturally Brewed Soy Sauce" is indeed free of artificial additives, relying on a traditional fermentation process with just water, soybeans, wheat, and salt. However, some of Kikkoman's other products, such as certain foodservice varieties, include preservatives like sodium benzoate for extended shelf life. For the consumer, this means the most reliable way to know if your Kikkoman soy sauce has additives is to check the ingredient list on the bottle. If you're seeking a pure, unadulterated product, stick to the naturally brewed and organic versions.
The Brewing Process: A Traditional Art
- Kikkoman soy sauce is naturally brewed: Kikkoman uses a traditional fermentation process, similar to making wine or beer, which can take several months.
- Four core ingredients: The base for their naturally brewed sauce is water, soybeans, wheat, and salt.
- No artificial additives: Kikkoman's standard product contains no artificial colors, flavors, preservatives, or added MSG.
- Sodium benzoate in some products: Specific foodservice or bulk versions may include sodium benzoate for preservation, so checking the label is essential.
- Rich umami flavor: The long fermentation process naturally develops the complex, savory taste known as umami.
Kikkoman and Quality
Kikkoman's reputation for quality stems from their adherence to the traditional brewing method and their use of high-quality, often non-GMO, ingredients. The company has been producing soy sauce for over 300 years, with the classic recipe and process being a core part of its identity. This commitment is what distinguishes its naturally brewed product from many chemically processed alternatives on the market.
A Global Product with Local Variations
Kikkoman products are produced in various locations around the world, including the US and Europe, to ensure consistent supply. While the core recipe and process are generally maintained, there can be minor ingredient differences or additions to suit local regulations or market needs, such as the use of a preservative in some commercial-sized containers. Therefore, consumers should always consult the specific product label for the most accurate information.
Conclusion: A Clear Ingredient List is Your Best Guide
When the question is "Does Kikkoman soy sauce have additives?", the clearest answer is found by looking at the label. For the pure, naturally brewed experience, look for the standard or organic versions with just the four essential ingredients. If you see additional ingredients, such as sodium benzoate, it’s likely a specialty product designed for a specific purpose. Always read the label to ensure the product meets your preferences.
