An unopened bottle of oyster sauce lasts for 18-24 months. But once you open the bottle it doesn’t go for too long. It can be consumed within a week or two.

Can You Freeze Oyster Sauce?

I am sorry to say that oyster sauce is not the right one for freezing. Because it has high salt content which is a chemical compound made of sodium and chlorine. Once these two dissolve with water, they never freeze again and in this way, the salt of oyster sauce prevents freezing leaving the whole sauce a mess. This is the reason why the oyster sauce is not recommended for freezing.

However, some of the users prefer freezing oyster sauce as they have found that this can extend its shelf life despite its texture, flavour, and colour change. But you cannot defrost frozen oyster sauce at room temperature as it tends to develop some harmful bacteria that can ruin the whole sauce. Even you cannot even eat raw frozen oyster sauce for the same bacteria issue.
