How Long Does Oyster Sauce Last? Does Oyster Sauce Go Bad?

Many people believe that the best-by date mentioned on the bottle is tits expiry period.

However, that is incorrect because this is just an estimated date provided by the manufacturers until they believe the sauce gives its peak quality.

After this date, one can indeed have the sauce, but they will not get a similar taste as before.

It will begin to decline over time; therefore, one must keep their sauce intact from all the outer elements.

The usual shelf life of an opened bottle of oyster sauce can be stored for 3 to 6 months in the pantry.

When you are storing sauces, then keeping them at room temperature is fine; however, for entire protection, one can put them in the fridge.

The sauce can be kept in the refrigerator and retain its quality for 18 to 24 months.

Unopened oyster sauces last longer because they are unaffected by air, moisture, and other bacterial infections as they are sealed.

So it would be best to keep the lid of the oyster sauce bottle closed until you are sure to use the sauce.

After opening the sauce, it is advisable to use the sauce within six months instead of prolonging its storage.

How to Tell if Oyster Sauce Have Gone Bad?

• Mold Growth

Some people think the sauce is a liquid; thus, it will not grow any mold.

But if it gets exposed to moisture, then it will develop molds in no time.

Be sure to discard the sauce bottle once you find mold growth.

• Foul Odor

When you are unsure how long you have stored the oyster sauce, do not consume it immediately, as it can be harmful.
