If you're wondering whether your oyster sauce has gone bad, there are a few things to look for.
First, check the color of the sauce.
If it's significantly darker than when you first bought it, that's a sign that it's starting to go bad.
Additionally, if the sauce has developed any mold or off-colors, it's best to discard it.
Another way to tell if oyster sauce has gone bad is by smell.
If the sauce smells sour or fishy, it's no longer good to use.

If it tastes sour or otherwise off, it's time to throw it out.

Can You Freeze Oyster Sauce?

Keeping Oyster Sauce Fresh Longer
Even though oyster sauce is a fermented product, it doesn't keep forever.
If you don't think you'll use a whole bottle within 3 to 4 months of opening it, consider buying the smaller bottles or freezing what you won't use right away in an ice cube tray.
By following these tips, you can make sure your oyster sauce stays fresh and lasts as long as possible.
