Alternatively, it may be exposed to contaminants that compromise the integrity of the oyster sauce, altering its consistency or allowing the development of bacterial activity in its interior, necessitating the need to discard the product.

Avoid the heat

You may notice that oyster sauce bottles indicate that you refrigerate them to maintain the greatest taste possible.

Exact dates are difficult to predict since they rely on the quality of the products and the recipes used to prepare them. In general, the typical shelf life of all oyster sauces available on the market is one and a half to two years.
