Plus, we’ll highlight a few of the best soy sauce and gluten-free soy sauce alternatives to add to your cooking routine. From traditional Chinese soy sauce to kelp-based vegan stand-ins, these delicious condiments will satisfy all your stir-frying, sushi rolling, marinading, and dumpling dunking needs. 

What is Soy Sauce?

As the name suggests, soy sauce is a flavorful liquid condiment made from fermented soybeans, wheat, water, and salt. It’s a common ingredient in Asian cooking, making it one of the most popular soy products worldwide. The condiment is typically bottled but also comes in small plastic packets at takeaway restaurants. 

Soy sauce is best known for its delicious umami taste and deep brown color. The thin, dark-colored liquid has a salty, savory flavor that compliments rice, noodles, sushi, sashimi, and other Asian dishes. 

Because wheat is used in the fermentation process, conventional soy sauce is not gluten-free. Those with gluten sensitivities should look for soy sauce products labeled gluten-free or wheat-free. The most popular soy sauce alternatives are Japanese tamari and coconut aminos. While they don’t provide an identical flavor, they’re the closest alternative to the real thing. 

How Is Soy Sauce Made? 

The vast number of soy sauces available today comes in various colors and flavors, and from dark to light, thanks to different production methods and regional variations. While authentic varieties stick to the original combination of simple ingredients, lower-quality soy sauces often contain artificial flavoring and caramel color. 

To make traditional soy sauce, soybeans are first soaked in water. Then, the drained beans are mixed with wheat flour and a culturing mold before being left to ferment for a few days. Once the mixture has developed, water and salt are added. This mixture is then placed in a fermenting tank, where it will age for upwards of five to eight months. Once the fermentation process is complete, the mixture is mashed, drained, pasteurized, and bottled. 

To reduce costs and speed up the production process, lower-quality soy sauces often rely on chemical processes and production, where the soybeans are heated and mixed with wheat and hydrochloric acid to break down the proteins quickly. Because the resulting soy sauces don’t have the same flavor or aroma, companies often add artificial coloring, flavors, and extra salt to compensate. 

High-quality soy sauce will be labeled as “naturally brewed,” meaning that only natural fermentation was used. The ingredient list will show “hydrolyzed soy protein” or “hydrolyzed vegetable protein” if chemical production methods were used. 

Types Of Soy Sauce

Dark Soy Sauce vs. Light Soy Sauce

Light soy sauce or known as sheng chou in Chinese cooking, is usually reddish-brown with a thin consistency. Dark soy sauce or known as Lao chou in Chinese cooking is usually darker and thicker. It also offers a more intense and full-bodied flavor but less salty compares to the light version. This type of sauce is often used to give the dish a dark caramel color.

Chinese Soy Sauce Vs. Japanese Soy Sauce

Chinese-style soy sauce is made with 100 percent soy, while Japanese soy sauce is made with a mixture of soy and wheat. This gives Japanese soy sauce a sweeter, rounder flavor than Chinese soy sauce, which is saltier and bolder in flavor. This makes Japanese soy sauce a better dipping sauce while making Chinese soy sauce better for making stir fry.

Soy Sauces FAQ

Why you should pick organic soy sauce:

Did you know that nearly all soybeans grown in America are genetically modified? That’s right. The FDA reports that GMO soybeans make up 94% of all soybeans planted in 2018. Though studies have drawn a number of contradicting conclusions, the true health effects of genetically modified crops are still relatively unknown. 

Additionally, soy is one of the most common allergens, especially among children, where rates have increased substantially over the past two decades. Food scientists have recently begun to find evidence of a correlation between the prevalence of GMO foods and the increase in children with food allergies.

To find the best soy sauces, it’s best to stick to high-quality, organic, naturally-brewed products from reputable companies. If you’re worried about the potential adverse health effects of soy sauce, use a soy sauce alternative like tamari or liquid coconut aminos instead. 

Is soy sauce bad for you? 

As you just learned, not all soy sauce is created equal. While naturally brewed organic soy sauce has been shown to be beneficial for your health, steer clear from cheap, chemically-produced products with low-quality ingredients and artificial additives. These low-end soy sauces are often made using GMO soy and may contain carcinogens. Not to mention, they can also be loaded with sodium. If you are watching your sodium intake, low sodium options are available.

Though naturally-brewed soy sauce gets a bad reputation for its high sodium content, it contains high levels of antioxidants that may support heart health. A study by the National University of Singapore reported that dark soy sauce has ten times the antioxidant activity of red wine. 

2001 study by the United Kingdom Food Standards Agency found that over 22% of tested samples of chemically-produced soy sauce contain a carcinogen called ethyl carbamate, which has been linked to multiple types of cancer. As long as you stick to naturally-brewed organic products, soy sauce can be part of a healthy diet.
