Tamari and soy sauce, often sharing shelves in pantries and grocery stores, can easily be mistaken for one another due to their similar dark colors and savory, umami-packed flavors. However, these two soybean-based sauces possess distinct characteristics that set them apart. If you’ve ever wondered “What Is Tamari?” and how it differs from soy sauce, you’ve come to the right place. This guide will delve into the world of tamari, exploring its origins, production process, nutritional profile, and culinary uses, while highlighting the key distinctions between tamari and its more common counterpart, soy sauce.
Delving into Tamari: Definition and Origins
Tamari is a type of fermented sauce crafted primarily from soybeans, celebrated for its rich umami flavor profile. Its roots are believed to trace back to China, but it gained significant popularity and refinement in Japan. Interestingly, traditional tamari emerged as a byproduct of miso production. Miso, a staple in Japanese cuisine, is a paste made by fermenting soybeans with salt and koji (a type of mold starter). As miso matures and ferments, a liquid naturally separates from the paste – this liquid is the original form of tamari. The name “tamari” itself is thought to derive from the Japanese word “tamaru,” meaning “to accumulate,” aptly describing its origin as a collected byproduct.
Tamari Production: A Detailed Look
While traditionally a byproduct of miso, modern tamari production has evolved to meet consumer demand. Today, tamari is intentionally crafted through a dedicated process that still honors its fermentation heritage. The journey begins with soybeans, which are soaked and cooked until tender. These cooked beans are then combined with a koji culture, often Aspergillus oryzae, to create nuggets known as koji. This koji is crucial for the fermentation process.
The koji nuggets are then moved to a temperature-controlled incubation chamber where the mold culture begins to work its magic, breaking down the complex carbohydrates and proteins in the soybeans. After incubation, the koji is transferred to a fermentation tank. Here, it’s mixed with salt and water to create a mash called moromi. This moromi is the heart of tamari production.
The moromi undergoes a lengthy aging process, typically spanning several months, in the fermentation tank. During this time, enzymes from the koji, along with naturally occurring yeasts and bacteria, work together to transform the mixture. This fermentation process is responsible for developing tamari’s characteristic flavor, color, and aroma. Finally, once the aging process is complete, the moromi is pressed to extract the liquid tamari, which is then pasteurized and bottled, ready to bring its umami depth to your kitchen.
Tamari vs. Soy Sauce: Key Differences Explained
Although both tamari and soy sauce are fermented soybean sauces prized for their umami flavor, several key distinctions set them apart, impacting their taste, texture, and suitability for different dietary needs. The primary differences lie in their ingredients and production methods.
Ingredients & Production Methods
Traditional soy sauce, particularly in Japanese and Chinese styles, typically includes four core ingredients: soybeans, wheat, water, and salt. The production of soy sauce also involves a koji fermentation process similar to tamari, but the inclusion of wheat is a significant differentiator. Wheat and soybeans are often cooked together before being combined with koji and a saltwater brine to form the moromi.
In contrast, traditional tamari is made with little to no wheat. Many tamari brands, especially those labeled gluten-free, are produced using only soybeans, water, salt, and sometimes a rice flour or rice koji as a starter culture. This difference in grain content is the most crucial factor distinguishing tamari and soy sauce.
Flavor Profile
Due to its higher concentration of soybeans and often the absence of wheat, tamari generally exhibits a richer, more robust, and less salty flavor compared to traditional soy sauce. Many describe tamari’s taste as smoother and more mellow, with a deeper umami presence. Soy sauce, on the other hand, often has a brighter, saltier, and slightly sharper flavor profile, partly attributed to the wheat content.
Texture
Tamari tends to be slightly thicker in consistency than soy sauce. While both are pourable liquids, tamari’s subtle thickness can be noticeable, contributing to its richer mouthfeel.
Gluten Content
Perhaps the most critical difference for many consumers is gluten content. Traditional soy sauce, because it contains wheat, is not gluten-free. This poses a problem for individuals with celiac disease, gluten sensitivity, or wheat allergies. Tamari, especially varieties specifically labeled “gluten-free,” offers a safe alternative. Because tamari is traditionally made without wheat (or with minimal wheat in some older styles), it is naturally gluten-free. However, always check the label to ensure the tamari you choose is certified gluten-free if you have dietary restrictions, as some commercial brands may add small amounts of wheat or process tamari in facilities that handle wheat.

Nutritional Comparison: Tamari and Soy Sauce Head-to-Head
Both tamari and soy sauce contribute minimal calories, fat, and carbohydrates to your diet while delivering a significant punch of umami flavor. However, there are subtle nutritional differences, primarily concerning sodium and gluten content.
Here’s a nutritional comparison based on 1 tablespoon (approximately 15ml) servings, according to USDA data:
| Nutrient | Tamari (1 tbsp) | Soy Sauce (1 tbsp) |
|---|---|---|
| Calories | 11 | 9 |
| Protein | 2g | 1g |
| Total Fat | 0g | 0g |
| Carbohydrates | 1g | 1g |
| Sugar | 0g | 0g |
| Sodium | 1010mg | 878mg |
As you can see, both sauces are high in sodium. While tamari has slightly more sodium per tablespoon in this comparison, the difference is not drastic. Excessive sodium intake can contribute to health issues like bloating and headaches. Fortunately, many brands offer reduced-sodium versions of both tamari and soy sauce. Opting for low-sodium tamari or soy sauce is a smart choice to manage sodium intake without sacrificing flavor. Low-sodium soy sauce typically contains around 511mg of sodium per tablespoon, a significant reduction.
The most significant nutritional difference, as mentioned earlier, is gluten. Tamari is inherently gluten-free (especially certified gluten-free varieties), making it suitable for gluten-free diets, while traditional soy sauce is not.
How to Use Tamari: Culinary Applications and Tips
Tamari and soy sauce can often be used interchangeably in recipes, both lending their savory umami depth to a wide array of dishes. However, tamari’s richer flavor and gluten-free nature make it a preferred choice for many, especially those with dietary restrictions or seeking a more nuanced taste.
Tamari shines in:
- Gluten-Free Cooking: It’s the go-to soy sauce alternative for anyone avoiding gluten.
- Marinades and Sauces: Its robust flavor enhances marinades for meats, poultry, tofu, and vegetables, and adds depth to stir-fry sauces, dipping sauces, and glazes.
- Soups and Stews: A splash of tamari can enrich the umami profile of soups, stews, and broths.
- Grain Bowls and Vegetarian Dishes: It’s excellent for seasoning grain bowls, roasted vegetables, and vegetarian or vegan meals, adding a savory touch.
Tips for using tamari:
- Start with less: Tamari’s flavor is more concentrated, so start with a smaller amount than you might use with soy sauce and adjust to taste.
- Gluten-Free Assurance: Always check for “gluten-free” labeling if you require it, and be mindful of cross-contamination if you have severe allergies.
- Experiment in Recipes: Don’t hesitate to substitute tamari for soy sauce in your favorite recipes to experience its unique flavor profile. Try it in dishes like noodle bowls, stir-fries, or even as a seasoning for eggs.
The Bottom Line
Tamari is a flavorful and versatile fermented soybean sauce, distinct from soy sauce primarily due to its production process and often gluten-free nature. While both sauces deliver umami richness, tamari offers a deeper, smoother flavor and is the ideal choice for those seeking a gluten-free alternative to soy sauce. Whether you’re gluten-free or simply looking to explore new flavors, understanding “what is tamari” and how to use it can elevate your cooking and add a delicious umami dimension to your meals. Consider trying tamari in your next recipe and discover the subtle yet significant difference it can make.
