Questions About This Product
The things people actually want to know before they cook with it.
What is the difference between the red-cap Kikkoman and the green-cap Less Sodium version?
They are separate products, not different packaging of the same sauce. The standard bottle is Kikkoman's traditionally brewed soy sauce, while the green-label version is brewed the same way and then has a substantial portion of its salt removed. Kikkoman also treats them differently after opening, specifically directing that the Less Sodium sauce be refrigerated with the cap kept tight, since it is more sensitive once the seal is broken.
Is Kikkoman soy sauce the same thing as tamari?
No. Kikkoman's standard soy sauce is a Japanese-style shoyu brewed from water, soybeans, wheat and salt, so wheat is an intentional part of the recipe and contributes to its rounder, slightly sweeter flavor. Tamari is brewed without wheat, and Kikkoman sells separate gluten-free tamari products certified to under 10 parts per million by the Gluten Free Certification Organization. If you need gluten-free, the standard bottle is not the one to reach for.
Is this soy sauce made in Japan or in the United States?
Kikkoman soy sauce sold in the US market is brewed in the United States. The company opened its Walworth, Wisconsin plant in 1973, the first Japanese food manufacturing facility built in America, and later added West Coast production. The brewing method itself is the traditional Japanese process, carried out on US soil, and the bottle states where it was made.
What does naturally brewed actually mean on the label?
It means the sauce is fermented over a period of months, with soybeans and wheat inoculated and left to develop, rather than produced by rapidly hydrolyzing soy protein with acid. Chemically produced soy sauces can be made in days and typically list hydrolyzed vegetable protein and added flavorings. The four-ingredient list on a naturally brewed bottle, water, soybeans, wheat and salt, is the practical tell.
Does Kikkoman soy sauce contain alcohol?
Yes. Kikkoman states that its soy sauces contain greater than two percent alcohol by volume, produced as a natural result of fermentation rather than added. This matters for anyone observing halal guidelines, and Islamic scholars are not unanimous on whether fermentation-derived alcohol in soy sauce is acceptable, so opinions differ by ruling and by school. Anyone following that guidance should consult the authority they normally rely on rather than assume a single answer.
Can I use Kikkoman where a recipe calls for Chinese light or dark soy sauce?
For light soy sauce it usually works, though Japanese shoyu is somewhat less salty and more aromatic, so taste and adjust rather than pouring the full amount. For dark soy sauce it is a poor substitute, because dark soy is thicker, less salty and used largely for the deep mahogany color it lends to braises. Substituting Kikkoman for dark soy will give you the seasoning but not the color or body.
Why does the label say All Purpose Seasoning instead of just soy sauce?
That wording appears on Kikkoman's US retail bottles and reflects how the company positions the product, as a general seasoning rather than a strictly table-side dipping sauce. It causes regular confusion for shoppers who think they have picked up a different or blended product. The sauce inside is Kikkoman's standard naturally brewed soy sauce.
Where is the date code on a Kikkoman bottle?
Kikkoman prints its dates on the bottle neck, on the cap, or on the top of the package depending on the format. The company frames it as a Best If Used By date and says it cannot vouch for quality past that point. It is a quality date rather than a safety cliff, but Kikkoman's own guidance is to use the product before it.
Is Kikkoman soy sauce vegan?
Yes, Kikkoman lists its soy sauce, less sodium soy sauce, gluten-free varieties, tamari and umami joy sauce among its certified vegan products. The brewing process uses only water, soybeans, wheat, salt and microbial cultures. This is a formal certification rather than an inference from the ingredient list.
What is the difference between Kikkoman soy sauce and Kikkoman teriyaki sauce?
Teriyaki sauce is a finished, sweetened glaze built on top of brewed soy sauce, with additional sweeteners and often wine or mirin. Soy sauce is the base seasoning and has no added sugar. Because teriyaki contains those extra components, it burns more readily over high heat, which is why the two are not used the same way in a pan.
How many bottle sizes does Kikkoman soy sauce come in?
Kikkoman offers this soy sauce across a wide range of formats, including 5 fl oz in both bottle and tabletop dispenser, 10 fl oz, 15 fl oz, 20 fl oz, 40 fl oz and 2 quart. The sauce is the same in each; the size determines how long a bottle stays open in your kitchen. Since Kikkoman recommends using an opened bottle within about a month for peak flavor, a smaller size is often the better choice for occasional cooks.
Is Kikkoman soy sauce non-GMO?
Kikkoman sells its US retail soy sauce and less sodium soy sauce under a non-GMO designation, which appears on the product naming and labeling. Not every product in the wider Kikkoman range carries that designation, and foodservice bottles can differ from the retail line. The bottle in front of you is the authority, so check the label if the designation is the deciding factor for you.
