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.
