When it comes to an unopened bottle of teriyaki sauce, it really depends on the quality of the sauce. The best quality Teriyaki sauce will last much longer than a lower quality sauce.

Generally speaking, an unopened bottle of teriyaki sauce can last anywhere from 1 to 3 years. However, it is always best to check the expiration date on the bottle before using it.

Also, a store bought Teriyaki sauce lasts much longer (2+ years) than homemade Teriyaki sauce because of the way they’re made (fermentation). The sugar content of bottled Teriyaki sauce also aids in the sauce’s preservation.

But keep in mind that it won’t taste the same as a new bottle and will have different colors, textures, and flavors.

How Long Does Opened Teriyaki Sauce Last?

When it comes to opened teriyaki sauce, it really depends on how you store it.

The shelf life is much shorter when opened. It will only last for about a week if stored in an unsealed container or at room temperature.

However, if stored properly in a container in the fridge, an opened bottle can last up to 3 months. The Teriyaki sauce can also be frozen for up to 6 months in a clean, airtight container.

After that, most sauces will start to deteriorate and not be as good. So, if you have an opened bottle of teriyaki sauce that you are not using, be sure to finish it as early as possible.

Homemade teriyaki sauce will last for 3–4 weeks in the fridge. Store it in a clean, airtight container. If you notice the sauce starting to change color or develop mold, it’s time to toss it.

When it comes to homemade Teriyaki sauce, fresh is always best. Because ingredients are all preservative-free, the sauce won’t last forever in the fridge.

But if you have some leftover sauce, it’s still worth saving. Here’s how to tell if your sauce has gone bad and make it last as long as possible.

How To Tell If the Teriyaki Sauce Has Gone Bad?

The first thing you will want to do is check the expiration date on the bottle. If the sauce is past its expiration date, it is more likely to be spoiled.

However, other than that, there are a few telltale signs that it has gone bad. Utilize all three of your senses—sight, smell, and taste—to determine whether or not your teriyaki sauce is bad.

First and foremost, check the color of your stored sauce.

If your Teriyaki has changed colors and turned from a rich brown to a dull gray, it’s probably time to toss it; it is likely no longer safe to eat. If the sauce has become watery or has chunks floating in it, it is also time to say goodbye.

If everything looks good from the outside, do a sniff test.

Open up the bottle and take a deep breath through your nose. If the sauce has also developed a sour or off smell, it is also best to discard it.

If you’re still unsure, taste it.

Stir the bottle and place a small amount of sauce on your finger. If the sauce is no longer smooth and flavorful, or if it has an off-putting taste, it’s probably time to toss it out.

Anything that was airtightly sealed in a bottle or jar can still be consumed without risk years beyond the expiry date. The same thing also applies to Teriyaki.

Sure, it won’t be the same, and the ingredients will degrade over time, but it’s very unlikely that they can “grow” something that may be harmful to you. If your Teriyaki sauce is bad, you will quickly notice or smell anything unsafe about that product!

However, in this case, it’s best to trust your gut feeling (literary!). Remember, it’s always better to be safe than sorry when in doubt!

How To Store Teriyaki Sauce to Make It Last for Longer?

When storing your teriyaki sauce, you can do a few things to make it last for longer. Here are a few tips to increase your Teriyaki sauce shelf life:

  • Store in an Airtight Glass Container

First, if you have any leftovers, you can store them in an airtight container in the fridge. Teriyaki sauce is best when stored in a cool, dark place out of direct sunlight, like a kitchen cabinet. This will help keep the sauce from drying out, getting oxidized, and the flavors from going bad.

Also, you should always store teriyaki sauce in a glass container. This will help to keep the sauce from absorbing any flavors from the container.

  • Freeze the Sauce

Another tip is to freeze Teriyaki sauce. This is a great way to extend the shelf life of the sauce. Simply pour the sauce into an ice cube tray and freeze. Once frozen, you can store the sauce cubes in a freezer bag for future use.

When you’re ready to use the sauce, simply thaw the desired amount and use it as normal. When reheating, be sure not to overcook the sauce, making it thick and sticky. If your sauce has become too thick, add a little water or chicken broth to thin it out.

This is a great way to always have fresh-tasting sauce on hand!

A free tip: Label your sauce with the date it was made/used. This will help you remember how long it has been in the fridge or freezer.

Following these tips, your teriyaki sauce should last for quite some time. You may also want to know Does Soy Sauce Go Bad?
