Yogurt, a creamy and nutritious delight enjoyed by many, has become a staple in our refrigerators. With its numerous health benefits and versatility, it’s no wonder yogurt has gained popularity worldwide. But have you ever wondered if yogurt actually expires? How long can it be safely consumed before it’s time to bid farewell to that tub of goodness?
In this blog post, we’ll explore the topic of yogurt expiration and delve into how long yogurt typically lasts. Understanding yogurt’s shelf life can help you make informed choices about consuming and storing this beloved dairy product. So, let’s uncover the secrets behind yogurt’s lifespan and ensure we savor every spoonful without compromising our health.
Yogurt does indeed have an expiration date, typically indicated on the packaging as the “expiration date” or “best before” date. This date serves as a guideline provided by the manufacturer to guarantee the quality of the product. It’s important to note that the expiration date primarily refers to the period during which the yogurt is expected to retain its optimal taste, texture, and nutritional value, rather than being an indication of safety.
The shelf life of yogurt depends on various factors, including the type of yogurt, the manufacturing process, and the storage conditions. Generally, yogurt can last anywhere from one to three weeks beyond its printed expiration date if stored properly. However, it’s essential to remember that this is merely an estimate and individual yogurts may vary.
The Average Shelf-Life For Most Yogurt Brands
Here is a table of the average shelf-life for some famous yogurt brands:
| Brand | Type | Shelf-life (unopened) | Shelf-life (opened) |
|---|---|---|---|
| Chobani | Greek yogurt | 1 month | 5-7 days |
| Dannon Oikos | Greek yogurt | 1 month | 5-7 days |
| Yoplait | Yogurt with fruit | 2 weeks | 7 days |
| Siggis | Icelandic yogurt | 1 month | 7 days |
| Noosa | Greek yogurt | 1-2 months | 7-10 days |
It is important to note that these are just average shelf-lives and the actual shelf-life may vary depending on the specific brand and type of yogurt.
What is really meant by the expiration date of Yogurt?
The expiration date on yogurt is the date by which the manufacturer guarantees that the yogurt will be of the highest quality and safe to eat. However, it is important to note that yogurt can still be safe to eat even after the expiration date. The expiration date is simply a guideline.
How Long Does Yogurt Last in the Fridge Once Opened?
Yogurt can last for 5-7 days in the fridge once opened. However, the shelf life of yogurt can vary depending on a number of factors, including the type of yogurt, the storage conditions, and the appearance of the yogurt.
What happens when you eat expired yogurt?
Eating a slightly expired yogurt, meaning it is just a few days past its expiration date, generally poses a lower risk compared to consuming yogurt that is significantly expired. In such cases, the yogurt might still be safe to eat depending on various factors, including the specific conditions of storage and the overall quality of the product.
Here are a few possibilities when consuming slightly expired yogurt:
- No noticeable effects: If the yogurt has been stored properly and shows no signs of spoilage, you may not experience any negative effects. Some yogurt products remain safe and consumable for a few days or even weeks after the expiration date, especially if they have been refrigerated at the correct temperature.
- Mild digestive discomfort: In some cases, eating slightly expired yogurt may cause mild digestive issues such as bloating, gas, or a slightly upset stomach. These symptoms are typically temporary and should subside on their own without requiring medical intervention.
- Increased risk of foodborne illness: While the risk is relatively low, there is still a possibility of harmful bacteria present in the slightly expired yogurt. If the yogurt has been contaminated or not stored properly, it could increase the likelihood of foodborne illnesses such as food poisoning. The severity of any resulting illness would depend on the specific bacteria and the individual’s susceptibility.
- To minimize the risk of consuming expired yogurt, it is always advisable to follow storage guidelines, including keeping yogurt refrigerated at the appropriate temperature and discarding any yogurt that exhibits signs of spoilage, such as an off smell, unusual texture, or visible mold growth.
Homemade vs store-bought yogurt?
The shelf life of homemade yogurt and store-bought yogurt can vary depending on a number of factors, including the type of yogurt, the ingredients used, and the storage conditions. However, in general, homemade yogurt has a shorter shelf life than store-bought yogurt.
Here are some factors that can affect the shelf life of yogurt:
- Type of yogurt: Some types of yogurt, such as Greek yogurt, have a longer shelf life than other types of yogurt, such as yogurt with fruit.
- Ingredients used: Yogurt made with whole milk has a shorter shelf life than yogurt made with low-fat or non-fat milk. Yogurt that contains added sugar or other sweeteners also has a shorter shelf life.
- Storage conditions: Yogurt should be stored in the coldest part of the refrigerator, which is usually the back. Yogurt should also be stored in an airtight container to prevent it from drying out or picking up flavors from other foods.
Homemade yogurt typically has a shelf life of 1-2 weeks in the refrigerator, while store-bought yogurt can have a shelf life of up to 2 months. However, it is always best to check the expiration date of the yogurt before you eat it.
What does spoiled yogurt taste like?
Spoiled yogurt can have a sour, bitter, or off-taste. It may also have a moldy smell. The sour taste is caused by the fermentation of lactose, the sugar in milk, by the yogurt’s beneficial bacteria. However, if the sour taste is strong or unpleasant, it is a sign that the yogurt has gone bad. The bitter taste is caused by the growth of harmful bacteria, which can produce toxins. The off taste is a general term for any taste that is not pleasant or expected.

How to tell if yogurt goes bad?
There are a few signs that can indicate if yogurt has gone bad. These include:
- Changes in appearance: Yogurt should have a smooth, creamy texture. If it has a lumpy or curdled texture, it may be spoiled. Yogurt may also develop a layer of liquid on top, which is called whey. This is normal and does not mean the yogurt is spoiled. However, if the whey is cloudy or has a strange color, the yogurt may be bad.
- Changes in smell: Yogurt should have a slightly sour smell. If it has a strong sour smell, it may be spoiled. Yogurt may also develop a moldy smell, which is a sure sign that it is bad.
- Changes in taste: Yogurt should taste fresh and creamy. If it has a sour, bitter, or off-taste, it may be spoiled.
If you notice any of these signs, it is best to throw away the yogurt. It is not worth the risk of getting sick from eating spoiled yogurt.
Can a refrigerator extend the shelf-life of a yogurt?
A refrigerator can extend the shelf-life of yogurt by keeping it at a cold temperature, which slows down the growth of bacteria that can cause the yogurt to spoil. The ideal temperature for storing yogurt is 35-40 degrees Fahrenheit.
Yogurt should be stored in the coldest part of the refrigerator, such as the back. It should also be stored in an airtight container to prevent it from drying out or picking up flavors from other foods. Yogurt should not be stored near strong-flavored foods, as they can impart their flavors to the yogurt. Yogurt should not be stored for more than 1-2 weeks after opening. After this time, the yogurt may start to spoil and become unsafe to eat.
Can You Freeze Yogurt?
Yes, you can freeze yogurt. Yogurt can be frozen for up to 2 months. However, the texture of the yogurt may change slightly after freezing and thawing. The yogurt may become slightly grainy or watery. To minimize this, you can blend the yogurt after thawing.
Here are some tips on how to freeze yogurt:
- Freeze yogurt in airtight containers. This will help to prevent the yogurt from picking up any flavors from other foods in the freezer.
- Label the containers with the date you froze the yogurt. This will help you to keep track of how long the yogurt has been frozen.
- Freeze yogurt in small batches. This will allow you to thaw only the amount of yogurt you need at a time.
- Thaw yogurt overnight in the refrigerator. This will help to prevent the yogurt from becoming too watery.
You can use frozen yogurt in a variety of ways, such as:
- In smoothies
- In baking

If you are looking for a way to extend the shelf life of yogurt, freezing is a great option. Just be sure to thaw the yogurt properly to minimize any changes in texture.
Can you heat expired yogurt?
No, you should not heat expired yogurt. Heating expired yogurt will not kill harmful bacteria that may have developed in the yogurt. In fact, it may actually make the bacteria more potent. If you have expired yogurt, it is best to throw it away.
What makes yogurt go bad?
Yogurt can go bad due to the growth of bacteria, which can happen if yogurt is not stored properly. Here are some of the factors that can make yogurt go bad:
- Temperature: Yogurt should be stored in the refrigerator at a temperature of 35-40 degrees Fahrenheit. If yogurt is stored at room temperature or in a warmer environment, bacteria can grow more quickly and spoil the yogurt.
- Exposure to air: Yogurt should be stored in an airtight container to prevent exposure to air. Air contains bacteria that can contaminate the yogurt and cause it to spoil.
- Opening the container: Each time you open the container of yogurt, you expose it to air and bacteria. This increases the risk of spoilage.
- Type of yogurt: Some types of yogurt, such as flavored yogurts, may have a shorter shelf life than plain yogurt. This is because flavored yogurts often contain added sugars, which can provide food for bacteria.
