How Long Does Yogurt Last?

How Long Does Yogurt Last?

How Long Does Yogurt Last? Yogurt is a dairy product produced by the bacterial fermentation of milk. Because of this, many people ask "does yogurt go bad?" and the answer is yes - but not as quickly as you might think. Yogurt comes in numerous flavors and varieties such as low-fat yogurt, frozen yogurt, Greek 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 it is stored.

So how long does yogurt (yoghurt) last past its sell by date?

When properly stored, yogurt lasts past its printed date for the time periods indicated below:

Yogurt Expiration Date

(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. But remember, like a lot of other dairy products, it 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 it to compliment your favorite meals even after its printed date has lapsed.

How to tell if Yogurt is bad, rotten or spoiled?

Practicing proper hygiene and food safety techniques will help prevent food born 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 at that point you must throw the entire container away, no matter what. Live bacterial cultures in yogurt act as a preservative, but once those cultures start to die off then mold can start to form. Never consume mold in any shape or form!

There are, of course, certain health risks associated with spoiled foods, so always remember to practice food safety and enjoy your foods before their shelf life has expired!

How to store Yogurt to extend its shelf life?

You can help all dairy products stay fresh longer by storing them in your refrigerator immediately after purchase. Once the package has been opened, yogurt can be kept for a few days if it is stored with the foil seal re-sealed (or in a tightly closed container) to keep out moisture and other contaminants. For a long-term option, you can freeze your yogurt for a month or two while preserving its taste (but at the same time killing off a small number of the multitudes of bacteria), if you use a freezer safe container.

Some benefits of proper food storage include eating healthier, cutting food costs and helping the environment by avoiding waste.
