Understanding How Less Sodium Is Achieved
Many people assume that reduced sodium soy sauce is merely regular soy sauce diluted with water, leading to a weaker flavor profile. This is a common misconception. The reality is far more sophisticated and involves a specialized process that takes place after the initial fermentation and aging are complete.
The traditional brewing of soy sauce requires a significant amount of salt, which acts as a preservative and helps control the fermentation process. Instead of reducing the salt from the beginning, manufacturers like Kikkoman brew their reduced sodium varieties in the exact same manner as their regular soy sauce. Only after the rich flavor and umami have fully developed is approximately 40% of the salt carefully extracted through a desalination process. This method ensures that the final product retains the complex, savory notes of traditional soy sauce while offering a significantly lower sodium level.
The Flavor Impact: Saltiness vs. Umami
Because the umami-rich compounds are created during the fermentation phase before the salt is removed, reduced sodium soy sauce is able to deliver a satisfying depth of flavor without the aggressive saltiness of its regular counterpart. The flavor difference between the two is distinct, not just a matter of dilution. Regular soy sauce delivers a strong, salt-forward punch, whereas the reduced sodium version is more subtle and allows other flavors in a dish to shine.
Practical Usage and Considerations
Choosing between regular and reduced sodium soy sauce often depends on the specific culinary application. For recipes where you want a concentrated, salty kick, regular soy sauce is the classic choice. However, for dishes that require a larger volume of soy sauce—such as marinades, braising liquids, or sauces—the reduced sodium version offers a significant advantage. It allows you to build a deep umami base without the risk of over-salting the entire dish.
For those managing their sodium intake for health reasons, such as high blood pressure, the reduced sodium variety is a clear winner. It provides the familiar flavor profile with fewer health risks. It's important to remember that even reduced sodium soy sauce still contains salt and should be used in moderation.
Comparison Table: Regular vs. Reduced Sodium Soy Sauce
| Feature | Regular Soy Sauce | Reduced Sodium Soy Sauce |
|---|---|---|
| Sodium Content | Higher (typically ~900-1000mg per tbsp) | Lower (typically ~550-600mg per tbsp) |
| Taste Profile | More prominent and aggressive salty taste | Less overtly salty, allows other flavors to stand out |
| Production Method | Standard fermentation and aging process | Standard brewing, followed by a post-brewing salt extraction |
| Best For | Finishing dishes, small quantities for seasoning | Marinades, braising, dipping sauces, larger quantities in recipes |
| Shelf Life | Longer due to higher salt content (natural preservative) | Shorter once opened; refrigeration is recommended |
Benefits of Choosing Reduced Sodium Soy Sauce
- Healthier Alternative: Lower sodium levels support better cardiovascular health by helping to manage blood pressure.
- Greater Recipe Control: Provides more control over the final saltiness of a dish, especially when used in large quantities.
- Balanced Flavors: The reduced salt allows the naturally fermented, savory umami flavors to be more prominent, creating a more complex taste experience.
- Diet-Friendly: An excellent option for individuals on low-sodium diets or for those who simply want to reduce their daily salt intake without compromising taste.
The Final Verdict on Saltiness and Flavor
Ultimately, reduced sodium soy sauce is indeed less salty than its regular counterpart. However, this reduction in salt is not a compromise on flavor but a refinement. The unique production process that removes salt after fermentation allows the complex umami character to shine through, providing a different but equally rich taste experience. While a bolder, salt-forward flavor may be preferred for some applications, the reduced sodium version is a versatile and healthier alternative for general cooking and dipping. For those mindful of their health, the benefits are clear, making it a valuable addition to any pantry. A balanced approach to sodium is key, and this product provides an excellent tool for achieving it without sacrificing culinary satisfaction.

Conclusion
Reduced sodium soy sauce is a carefully crafted condiment that delivers less salt but preserves the essential umami flavor. It is a distinct product from its regular version, not merely a diluted imitation. By understanding its production and flavor profile, home cooks can use it strategically to manage their sodium intake while still creating delicious, well-balanced meals. The choice between regular and reduced sodium depends on the desired saltiness level and dietary needs, but for a healthier and more nuanced flavor, reduced sodium is an excellent choice.
