If you’ve ever eaten Vietnamese food or perused through an Asian supermarket, chances are you’ve come across fish sauce. Maybe you have a bottle at home and are unsure whether it’s still safe for consumption.
Quick Answer
Fish Sauce does lose its flavor and spoils over time, but its shelf life is significantly longer than other condiments and sauces. Unopened fish sauce has a shelf life of 3-5 years when kept out. Refrigeration will keep fish sauce fresh for 3 years after it’s been opened. Freezing is not advisable as your freezer is not cold enough to freeze fish sauce.
