Soy sauce, a cornerstone of Asian cuisine and increasingly popular globally, comes in myriad forms. Among the leading brands, Kikkoman enjoys widespread recognition. A common question that arises is whether Kikkoman soy sauce is truly naturally brewed, a process that significantly impacts flavor, aroma, and overall quality. Let’s delve into the intricacies of soy sauce production and uncover the truth behind Kikkoman’s brewing process.
Understanding Soy Sauce Brewing Methods
There are several methods to produce soy sauce, each yielding distinct characteristics. Understanding these methods is crucial to evaluating whether Kikkoman aligns with the traditional, naturally brewed approach.
The Traditional Brewing Process: A Time-Honored Tradition
The traditional, or naturally brewed, method of soy sauce production is a labor-intensive, time-consuming process that has been refined over centuries. It involves the careful cultivation of koji, a mold culture, and its interaction with soybeans, wheat, salt, and water.
The process typically begins with the mixing of cooked soybeans and roasted, crushed wheat. This mixture provides the base for koji to thrive. Next, the koji spores are introduced, and the mixture is carefully incubated, allowing the koji mold to grow and break down the complex carbohydrates and proteins into simpler sugars and amino acids. This process can take several days.
Once the koji fermentation is complete, the mixture, now called koji, is combined with a saltwater brine. This creates a mash called moromi, which is then transferred to large fermentation tanks. Here, the magic happens. Over several months, or even years, the enzymes from the koji continue to break down the soybeans and wheat, resulting in the complex flavors and aromas characteristic of naturally brewed soy sauce.
Throughout the fermentation period, the moromi is carefully monitored and stirred to ensure even fermentation. This meticulous process allows for the development of hundreds of flavor compounds, contributing to the rich, umami-packed taste.
After fermentation, the moromi is pressed to separate the liquid soy sauce from the solids. The raw soy sauce is then pasteurized to stop further fermentation and stabilize the flavor. Finally, it is filtered and bottled.
Acid-Hydrolyzed Soy Sauce: A Chemical Shortcut
In contrast to the traditional method, acid-hydrolyzed soy sauce production is a much faster and cheaper process. It involves using hydrochloric acid to break down soybeans into amino acids. This method bypasses the natural fermentation process altogether.
The acid hydrolysis process typically takes only a few hours. The soybeans are heated with hydrochloric acid, which breaks down the proteins into amino acids. The acid is then neutralized with an alkaline substance, and the resulting liquid is filtered and processed.
While this method is significantly faster and less expensive than natural brewing, it results in a soy sauce that lacks the complexity and depth of flavor found in naturally brewed varieties. Acid-hydrolyzed soy sauce often has a harsher, more chemical taste. Coloring and flavor enhancers are frequently added to improve its palatability.
Blended Soy Sauces: A Combination of Methods
Some soy sauces are produced using a combination of both the naturally brewed and acid-hydrolyzed methods. This allows manufacturers to create a product that is less expensive than purely naturally brewed soy sauce but still offers some of the flavor characteristics associated with fermentation.
The proportions of naturally brewed and acid-hydrolyzed soy sauce can vary widely, depending on the desired flavor profile and cost. Blended soy sauces may also contain added coloring, flavoring, and preservatives.
Kikkoman’s Brewing Process: A Closer Look
Now, let’s examine Kikkoman’s soy sauce production methods. Kikkoman proudly states that its traditionally brewed soy sauce is naturally fermented using a centuries-old process.
The Kikkoman Tradition: Natural Fermentation
Kikkoman uses a traditional brewing process for its flagship soy sauce. This involves carefully selecting high-quality soybeans, wheat, salt, and water. The company cultivates its own koji cultures, ensuring the consistent quality and flavor of its soy sauce.
The soybeans and wheat are prepared and mixed with koji, and the mixture is fermented in large tanks for several months. During this time, the enzymes from the koji break down the proteins and carbohydrates, developing the characteristic umami flavor and aroma.
Kikkoman meticulously monitors the fermentation process, ensuring that the temperature and humidity are optimal for the koji to thrive. This attention to detail is crucial for producing a high-quality, naturally brewed soy sauce.
Kikkoman’s Product Range: Different Options
While Kikkoman is renowned for its traditionally brewed soy sauce, it is important to note that the company also offers other types of soy sauce. Some of these may be produced using different methods or may contain additives.
For example, Kikkoman offers a less sodium version of its soy sauce, which is made through a slightly different process. It’s always essential to check the product label to understand the specific ingredients and brewing method used.
Identifying Naturally Brewed Kikkoman Soy Sauce
Identifying whether a Kikkoman soy sauce is naturally brewed is usually straightforward. Look for the words “naturally brewed” on the label. This indicates that the soy sauce was produced using the traditional fermentation process. The ingredient list should also be relatively simple, consisting primarily of water, soybeans, wheat, and salt.
If the label does not explicitly state “naturally brewed,” or if the ingredient list includes additives such as caramel coloring or hydrolyzed vegetable protein, it is likely that the soy sauce is not purely naturally brewed.
The Impact of Brewing Method on Flavor and Quality
The brewing method significantly impacts the flavor, aroma, and overall quality of soy sauce. Naturally brewed soy sauce boasts a complex and nuanced flavor profile that is difficult to replicate using other methods.
The Superior Flavor of Natural Brewing
Naturally brewed soy sauce has a rich, savory, and umami-packed flavor. The long fermentation process allows for the development of hundreds of different flavor compounds, creating a depth and complexity that is unmatched by acid-hydrolyzed or blended soy sauces. The taste is balanced, with subtle notes of sweetness and acidity.
Acid-hydrolyzed soy sauce, on the other hand, tends to have a harsher, more chemical taste. It lacks the subtle nuances and complexity of naturally brewed soy sauce. Additives are often used to mask the unpleasant flavors and improve its palatability.
Aroma and Color Differences
The aroma of naturally brewed soy sauce is also distinct. It has a pleasant, savory fragrance that is indicative of the fermentation process. Acid-hydrolyzed soy sauce often has a less appealing, more chemical odor.
In terms of color, naturally brewed soy sauce typically has a rich, reddish-brown hue. Acid-hydrolyzed soy sauce may be darker in color, often due to the addition of caramel coloring.
Nutritional Considerations
While soy sauce is primarily used for flavor, it also contains some nutrients. Naturally brewed soy sauce may contain beneficial compounds produced during fermentation, such as antioxidants. Acid-hydrolyzed soy sauce may contain fewer of these beneficial compounds.

Is all Kikkoman Soy Sauce naturally brewed?
No, not all Kikkoman soy sauce is naturally brewed. While Kikkoman is widely known for its naturally brewed soy sauce, they also produce variations that use different production methods. It’s crucial to check the label carefully to determine the specific brewing process used for the particular Kikkoman soy sauce you’re considering.
Specifically, look for terms like “naturally brewed” or “fermented” on the label, which indicates that the soy sauce has been produced using the traditional fermentation process involving soybeans, wheat, salt, and water. Some Kikkoman products may utilize a chemically hydrolyzed process, which results in a soy sauce with a different flavor profile and potentially different nutritional characteristics compared to naturally brewed varieties.
How can I tell if my Kikkoman Soy Sauce is naturally brewed?
The most reliable way to determine if your Kikkoman soy sauce is naturally brewed is by carefully examining the ingredients list and the front label. Look for the phrase “naturally brewed” or similar wording prominently displayed on the packaging. The ingredients list should include soybeans, wheat, salt, and water. These are the four essential ingredients in naturally brewed soy sauce.
If the label mentions hydrolyzed vegetable protein, caramel coloring, or other additives that aren’t typically found in traditional soy sauce recipes, it’s likely not naturally brewed. Also, note the price point; naturally brewed soy sauces are often slightly more expensive due to the longer and more labor-intensive production process.
What are the benefits of naturally brewed Kikkoman Soy Sauce?
Naturally brewed Kikkoman soy sauce offers a more complex and nuanced flavor profile compared to chemically produced soy sauces. The traditional fermentation process creates hundreds of different flavor compounds, resulting in a richer, smoother, and more balanced taste with subtle notes of sweetness, saltiness, umami, and acidity. This complex flavor enhances the overall culinary experience.
Additionally, naturally brewed soy sauce retains more of the natural amino acids and other beneficial compounds present in soybeans and wheat. While soy sauce should be used in moderation due to its sodium content, the natural fermentation process can contribute to a more wholesome and authentic flavor experience. It is often preferred by chefs and home cooks seeking superior taste and quality.
What is the difference between naturally brewed and chemically produced soy sauce?
The primary difference lies in the production method. Naturally brewed soy sauce is created through a slow fermentation process using soybeans, wheat, salt, and water. This fermentation, which can take several months, relies on natural enzymes and microorganisms to break down the proteins and carbohydrates, resulting in a complex flavor development.
Chemically produced soy sauce, on the other hand, is made using a process called acid hydrolysis. This process involves boiling soybeans in hydrochloric acid to break down the proteins and sugars. This is a much faster and cheaper method, but it results in a harsher, less complex flavor. Additives like caramel coloring and corn syrup are often added to mimic the color and sweetness of naturally brewed soy sauce.
Does naturally brewed Kikkoman Soy Sauce contain gluten?
Yes, naturally brewed Kikkoman Soy Sauce does contain gluten because it includes wheat as one of its primary ingredients. During the fermentation process, some of the gluten is broken down, but it is not completely eliminated. Therefore, it is not suitable for individuals with celiac disease or gluten sensitivity.
For those avoiding gluten, Kikkoman offers a Tamari Soy Sauce, which is traditionally made without wheat and is often considered a gluten-free alternative. However, it’s important to always check the label to ensure that the specific Tamari product is certified gluten-free, as some brands may still contain trace amounts of wheat or be processed in facilities that handle wheat.
How long does naturally brewed Kikkoman Soy Sauce last?
Unopened, naturally brewed Kikkoman Soy Sauce has a very long shelf life, often several years, and will typically retain its quality well past the “best by” date printed on the bottle. The high salt content acts as a preservative, inhibiting the growth of harmful bacteria.
Once opened, it’s best to store Kikkoman Soy Sauce in the refrigerator to maintain its optimal flavor and color. While it’s still safe to consume at room temperature, refrigeration helps to prevent the soy sauce from darkening and losing its subtle flavors over time. Properly refrigerated, opened Kikkoman Soy Sauce can last for a year or more without significant degradation in quality.
Why is naturally brewed Kikkoman Soy Sauce more expensive?
The higher cost of naturally brewed Kikkoman Soy Sauce is primarily due to the more complex and time-consuming production process. Traditional fermentation requires a significant investment in time, resources, and skilled labor to carefully manage the fermentation process and ensure consistent quality.
The acid-hydrolyzed method, used for chemically produced soy sauce, is significantly faster and cheaper, resulting in a lower production cost. This difference in production cost is reflected in the price consumers pay at the store. Consumers who prioritize quality, flavor, and a more authentic soy sauce experience are generally willing to pay the premium for naturally brewed varieties.
