• Shelf Life Expiration Date: How Long Does Yogurt Really Last?


    How Long Does Yogurt Last? Yogurt is a dairy product produced by the bacterial fermentation of milk.  It comes in numerous flavors and varieties such as low-fat yogurtfrozen yogurtGreek yogurt, yogurt with fruit and drinkable yogurt.  The beneficial active cultures it contains promote a healthy intestinal environment.  It is no wonder why yogurt (yoghurt) is one of the most popular dairy products in the world!  The shelf life of yogurt (yoghurt) and its ultimate expiration date depends on a variety of factors, such as its sell by date, its preparation method and how the yogurt is stored.  So how long does yogurt (yoghurt) last past its sell by date?

    When properly stored, yogurt (yoghurt) lasts for the time periods indicated below:

    (Unopened) Refrigerator Freezer
    Past Printed Date  Past Printed Date
    Frozen Yogurt lasts for 2-3 Months
    Drinkable Yogurt lasts for 7-10 Days 1-2 Months
    Greek Yogurt lasts for 1-2 Weeks 1-2 Months
    Reduced Fat Yogurt lasts for 1-2 Weeks 1-2 Months
    Yogurt lasts for 2-3 Weeks 1-2 Months
    Yogurt With Fruit lasts for 7-10 Days 1-2 Months
    (Opened) Refrigerator Freezer
    Past Printed Date  Past Printed Date
    All Opened Yogurt lasts for 1 Week 1 Month

    Of course, yogurt lasts for a shorter period of time if it is not stored properly (check out EatByDate’s recommended storage products).  But remember, yogurt, like a lot of other dairy products, usually has a sell by date which is simply the last date until which a manufacturer will vouch for a product’s quality, not its safety. All yogurt manufactures that we checked guarantee their product quality for 7 days beyond the printed sell by date, but do not state a timeframe for safety (although they agree yogurt can be eaten beyond the 7 days). Because of this distinction, you may safely use yogurt to compliment your favorite meals even after its printed date has lapsed.

    How to tell if yogurt (yoghurt) is bad, rotten or spoiled?

    Practicing proper hygiene and food safety techniques will help prevent food borne illness. Although not a perfect test, your senses are usually the most reliable instruments to tell if your yogurt has gone bad. A small amount of liquid is ok in most yogurts, it is called whey and actually contains several nutrients that should be mixed into the yogurt before eating. But an increased amount of surface liquid (or, in the case of Yoplait yogurt and a few others that do not have any excess liquid to begin with, it’s when a puddle begins to form) and a curdling texture near the bottom of the container are the first signs of yogurt going bad. The final sign is the formation of mold and you must then throw it out. Live bacterial cultures in yogurt act as a preservative, but once those cultures start to die off mold can start to form. There are, of course, certain health risks associated with spoiled yogurt, so always remember to practice proper food safety and enjoy your yogurt prior to its eat by date.
