The Ideal Way To Store Oyster Sauce Once It's Opened
A new bottle of oyster sauce should be stored in a cool environment away from direct sunlight, but once opened, it should always be stored in your refrigerator.
Ensure the lid or cap of your oyster sauce is sealed and airtight to limit air exposure, which can cause flavor deterioration and create an environment for bacteria to thrive.
If your oyster sauce comes in a shelf-stable can, transfer the sauce to an airtight plastic or glass storage container after opening, then refrigerate it.
If the sauce is in a glass bottle, keep it stored there, since glass helps maintain the sauce's integrity. The sauce should last up to two years if stored properly in the fridge.
