The 8 Best Soy Sauces of 2023

What to Look for in Soy Sauce

Type

Soy sauce, like barbecue sauce, comes in a wide range of styles. While it’s unlikely you’ll be able to sample the soy sauce at the local market, paying attention to the type of soy sauce will help you choose the one you like.

Typical soy sauces are made in either Japan or China, although some are made in other countries, including the United States. Styles range from light to dark, with plenty of variations. The good news is that soy sauce is an inexpensive condiment (until you move on to the artisan styles) so it’s simple to pick up a few different bottles at the grocery store to hone in on the ones you like the best.

Aging

Like wine or fine liquors, soy sauce may be aged. Longer aging creates deeper more complex flavors, but also adds to the cost. When the soy sauce will be mixed with other ingredients, used in a small quantity, or used primarily for the salty flavor, just about any sauce will suffice, whether it has been aged or not.

If the soy sauce will be used as a dipping sauce or its flavor is a major part of the recipe, it might be worth splurging on a sauce that was aged longer. Traditional soy sauces are aged for 5-8 months and are suitable for most uses, but for a real splurge, there are a number of soy sauces that are aged for up to 4 years.

Sodium Content

Soy sauce is very salty, but there are some that are lower in sodium or that have a much richer flavor so less can be used. It's a good idea to check the label.

FAQs

Does soy sauce go bad? 

Eventually, it might. While it’s unlikely, it could develop mold. The good news is that an unopened bottle of soy sauce is good for 2-3 years, and possibly longer. Most opened bottles of soy sauce are safe for at least a year thanks to the high salt content. However, the flavor may change over time, so if the soy sauce doesn’t seem as good as it used to be, it may be time to splurge on a fresh bottle.

Does soy sauce need to be refrigerated? 

Soy sauce is perfectly happy to hang out in a dark, cool cabinet. However, once the bottle is open, it’s fine to stash it in the fridge, particularly if it takes you longer than a year to finish the bottle.

How is soy sauce made? 

While the exact ingredients and process differ depending on who is making it, traditional soy sauce is made from soybeans, wheat, and a fermenting agent—typically a mold—along with salt and water. The sauce is aged for 5-8 months, although some artisan sauces are aged much longer. There are also very inexpensive soy sauces that are made using a chemical process, while others are fermented for just three weeks instead of the more traditional several months.

What is a good substitute for soy sauce?

Depending on the role of soy sauce, there are a number of substitutes. If the goal is the salty flavor, plain salt can be added. Coconut aminos, miso paste, or even fish sauce can add umami flavor. In some cases where a tangy flavor is a plus, Chinese black vinegar, balsamic vinegar, or Worcestershire sauce may also work well.

What's the difference between dark and light soy sauce?

Most soy sauces you may encounter are types of light soy sauce—takeout packets and the soy sauce at restaurants are usually this versatile type. It is thin and brown, may contain things like sugar and wheat flour, and takes a few months to make. Dark soy sauce is, of course, darker, but also thicker, sweeter, and less salty than light soy sauce. Swapping one for the other in recipes isn't recommended, as they do have vastly different flavors and textures.
