How Long Does Open Greek Yogurt Last? A Guide to Shelf Life and Storage

If you’re a fan of Greek yogurt, then you know how delicious and nutritious it is to have a bowl of it every day. Greek yogurt is a perfect breakfast or snack option that provides several health benefits, including essential probiotics to improve digestion and immunity. But what if you’ve already opened your Greek yogurt container and are wondering whether it’s still safe to eat? How long does open Greek yogurt last?

The shelf life of open Greek yogurt can be different depending on the brand and preservatives used. Generally, open Greek yogurt lasts up to ten days when stored in the fridge below 40°F. However, the flavor and texture can start to deteriorate after a week, and it won’t be as creamy and thick as fresh yogurt. Therefore, it’s always recommended to check the expiry date before buying Greek yogurt to ensure you enjoy it when it’s still at its best quality.

There are also certain signs that your open Greek yogurt has gone bad, indicating that you should immediately discard it. For example, if you notice any mold on the surface or an off smell, or taste, it’s better not to consume it. Instead, you can explore different yogurt-based recipes to use up the remaining yogurt and get creative with your cooking skills. With that being said, consuming fresh Greek yogurt is always the best option to get all the health benefits it has to offer.

What is Greek yogurt?

Greek yogurt is a popular and healthy dairy product that has been a staple in Greek cuisine for centuries. It is a thick and creamy yogurt that is made by straining regular yogurt to remove the liquid whey and lactose, resulting in a lower-carbohydrate and higher-protein product. The straining process also gives it a unique texture and tangy taste that sets it apart from regular yogurt. Greek yogurt comes in various flavors, including plain, vanilla, and fruit flavors, and is widely used in a variety of recipes, including dips, smoothies, and soups.

Different types of Greek yogurt

Greek yogurt has become a popular choice among health-conscious consumers. Known for its creamy texture and high protein content, Greek yogurt is a versatile dairy product. There are several types of Greek yogurt that offer various benefits.

  • Traditional Greek Yogurt: Made by straining the liquid whey from plain yogurt, this thick and creamy yogurt has a tangy flavor. It is high in protein, calcium, and probiotics that aid in digestion. Traditional Greek yogurt has a higher fat content than other types, with around 10g per 100g serving.
  • Low-fat Greek Yogurt: With less than 3g of fat per serving, this type of Greek yogurt is a healthier option for those watching their fat intake. It contains the same amount of protein and fewer calories than traditional Greek yogurt.
  • Non-fat Greek Yogurt: This type of Greek yogurt is fat-free and has a lower calorie count than the other types. It is an excellent option for those who need to limit their calorie intake and still get the benefits of Greek yogurt. However, non-fat Greek yogurt may not be as creamy or rich as the traditional or low-fat types.

Flavored vs. Plain Greek Yogurt

Flavored Greek yogurt has added sugars and flavors, which increase the calorie count. It also often contains fewer probiotics and a lower protein content than plain Greek yogurt. However, plain Greek yogurt might not appeal to everyone’s taste buds. A good compromise is to purchase plain Greek yogurt and add natural sweeteners, such as honey, fresh fruit, or granola.

Shelf Life of Open Greek Yogurt

Once opened, Greek yogurt should be consumed within 5-7 days. However, some brands of Greek yogurt may last longer, up to 10 days. Check the expiration date and manufacturer’s recommendations on the packaging. Proper storage can extend the shelf life of Greek yogurt. Store it in the coldest part of the refrigerator, away from strong-smelling foods, to prevent contamination of flavors.

Types of Greek Yogurt Calories per 100g serving Protein per 100g serving Fat per 100g serving
Traditional Greek Yogurt 97 10g 10g
Low-fat Greek Yogurt 76 10g 3g
Non-fat Greek Yogurt 56 10g 0g

It’s essential to choose a Greek yogurt that fits your dietary needs and preferences. Traditional Greek yogurt is a good choice for those looking for a full-fat option, while low-fat or non-fat Greek yogurt is great for those watching their fat and calorie intake. Plain Greek yogurt is the best option for controlling added sugars and getting the benefits of high protein and probiotics.

Nutritional benefits of Greek yogurt

Greek yogurt has gained popularity over the years due to its delicious taste and numerous health benefits. This yogurt is thicker, creamier and contains fewer amounts of lactose compared to other yogurts. Greek yogurt is packed with essential nutrients that are beneficial for your overall health.

  • High in protein: Greek yogurt is loaded with protein, making it an excellent choice for individuals who are physically active. A 6-ounce serving of Greek yogurt contains about 17 grams of protein, which is twice the amount found in regular yogurt.
  • Packed with probiotics: Greek yogurt contains live cultures of bacteria known as probiotics, which can help improve digestion and boost immunity. These beneficial bacteria help in the breakdown of lactose and other nutrients, making them more easily absorbed by the body.
  • Low in calories: Greek yogurt is a great snack option for people trying to lose weight. It is low in calories and high in nutrients, making it a perfect substitute for high-calorie, low-nutrient snacks.

Besides the above three benefits, Greek yogurt also provides other essential nutrients such as calcium, iodine, vitamin B12, and phosphorus. These nutrients are important for supporting good health and wellbeing.

If you are looking for a healthy, nutrient-packed snack, then Greek yogurt is a great option. Eat it plain or mix it with some fresh fruit for a tasty treat. But, like any other food, it is essential to consume it in moderation to avoid excessive intake of calories.

How long does open Greek yogurt last?

Now that we know the health benefits of Greek yogurt, how long does it actually last after opening the container?

The answer is, it depends.

If Greek yogurt is stored properly, it can last up to two weeks after opening. This means that if the yogurt has remained at a consistent temperature and has not been contaminated, it can still be consumed within two weeks.

However, it is important to note that Greek yogurt is prone to bacterial growth and contamination due to its high protein and low acidity levels. Thus, it is important to store the yogurt in a refrigerator at a consistent temperature of 40 degrees or less. Additionally, ensure that the yogurt is tightly sealed after each use to limit bacterial exposure.

Storage tips for Greek yogurt

Do not freeze Greek yogurt as it will ruin its texture.

In summary, Greek yogurt is a healthy and nutrient-packed snack that provides numerous health benefits. If stored properly, it can last up to two weeks after opening, and can be eaten plain or mixed with fresh fruit for a tasty treat.

Shelf life of open Greek yogurt

Greek yogurt has exploded in popularity in recent years due to its high protein content and smooth, creamy texture. While many people enjoy consuming it fresh from the fridge, there are times when you may open a container and not finish it all at once. This raises the question – how long does open Greek yogurt last?

  • Refrigeration: Like all dairy products, Greek yogurt needs to be stored in the refrigerator
  • Storage container: Make sure to use an airtight container to store leftover Greek yogurt. This will help prevent the growth of bacteria and mold
  • Expiration date: Check the expiration date on the container before consuming open Greek yogurt. Once the expiration date has passed, it’s time to dispose of the product

According to USDA, the shelf life of an opened container of Greek yogurt is approximately 7-10 days when stored in the refrigerator at or below 40°F. However, this is just a general guideline and the actual shelf life of your open Greek yogurt may vary depending on various factors such as the temperature of your refrigerator, the quality of the yogurt, and the level of hygiene during food handling.

If you notice any changes in the texture, odor, or taste of your open Greek yogurt, it’s best to throw it away. Signs that Greek yogurt has gone bad include the presence of mold, a sour smell, or a changed taste. Don’t take a chance on consuming spoiled yogurt as it can lead to food poisoning and other food-borne illnesses.

Storage method Shelf life (approximate)
Refrigerator, unopened container 4 weeks past the date printed on the container
Refrigerator, opened container 7-10 days
Freezer, unopened container (for long-term storage) Up to 2 months

In conclusion, while Greek yogurt is a delicious and nutritious food item, it’s important to follow proper storage guidelines to ensure that you’re consuming fresh and safe yogurt. When in doubt, always err on the side of caution and throw away any open Greek yogurt that has gone past its shelf life or shows signs of spoilage.

Factors that affect the shelf life of Greek yogurt

Greek yogurt is a popular breakfast option, used in smoothies, desserts, dips, and sauces. It is known for its thick, creamy texture and tangy taste, but it also has a limited shelf life. Proper storage and handling can help to extend the shelf life of Greek yogurt, but there are various factors that can affect its freshness and quality.

  • Ingredients: The freshness and quality of Greek yogurt depend on its ingredients. The milk used to make yogurt should be fresh, and the bacteria used to ferment milk (Lactobacillus bulgaricus and Streptococcus thermophilus) should be live and active. Preservatives and additives can also affect the shelf life of Greek yogurt, so it is important to read labels carefully.
  • Temperature: One of the most important factors that can affect the shelf life of Greek yogurt is temperature. Yogurt is a perishable food that should be kept cold at all times. When yogurt is exposed to temperatures above 40°F (4°C), the bacteria can become dormant or die, and the yogurt can spoil or develop off-flavors and odors. Therefore, it is recommended to store Greek yogurt in the refrigerator at a temperature between 32-39°F (0-4°C).
  • Exposure: Exposure to air and light can also affect the shelf life of Greek yogurt. Air can cause the yogurt to dry out and form a skin, while light can cause the yogurt to develop a sour taste and off-color. It is recommended to store Greek yogurt in airtight containers and avoid exposing it to direct sunlight or prolonged light exposure.
  • Contamination: Yogurt can be contaminated with harmful bacteria, viruses, or parasites that can cause foodborne illness. Cross-contamination can also occur when yogurt comes into contact with contaminated utensils, surfaces, or hands. It is important to practice good hygiene and food safety when handling and storing Greek yogurt.
  • Expiration date: Greek yogurt has a limited shelf life, and its freshness and quality decline over time. Therefore, it is important to check the expiration date on the container before consuming Greek yogurt. Yogurt that is past its expiration date can have a sour taste, bad smell, and mold growth, and should be discarded.


To summarize, the shelf life of Greek yogurt depends on various factors, including ingredients, temperature, exposure, contamination, and expiration date. To extend the shelf life of Greek yogurt, it is important to store it properly in the refrigerator, use airtight containers, avoid exposure to air and light, practice good hygiene and food safety, and check the expiration date before consuming it.

Signs of Spoiled Greek Yogurt

Greek yogurt is considered a healthy and delicious food product. However, like any other dairy product, Greek yogurt can spoil and go bad. It’s essential to check the freshness of the Greek yogurt before consuming it. Here are the signs to look out for:

  • Smell: Take a whiff of your Greek yogurt. If it has a sour, rancid smell, it’s a sign that the yogurt has gone bad.
  • Texture: Check the texture of the yogurt. If it appears lumpy or has a thin, watery consistency, it’s no longer fresh.
  • Mold: If you notice mold formation on the yogurt’s surface, it’s best to discard it.

If you consume Greek yogurt that has gone bad, it can cause food poisoning and unpleasant digestive symptoms. Therefore, it’s crucial to observe the yogurt’s freshness and discard it when needed.

It’s also worth mentioning that Greek yogurt can last longer than its expiry date if stored properly. The Yogurt’s shelf life depends on the storage temperature and conditions.

Factors that affect the shelf life of Greek Yogurt

Here are some of the factors that affect the lifespan of Greek Yogurt:

  • Exposure to Oxidation: When Greek yogurt is exposed to oxygen, it can lead to the growth of harmful bacteria, reducing its lifespan.
  • Storage Temperature: Greek yogurt should be stored at temperatures between 36-39°F. Higher temperatures will speed up the spoilage process.
  • Storage Conditions: Moisture, light, and heat are not suitable for storing Greek yogurt. It’s essential to keep it in a cool, dry place away from direct sunlight.

How Long Does Greek Yogurt Last?

Greek yogurt can generally last up to two weeks beyond its expiration date. However, its freshness and texture may start to deteriorate after ten days. While it’s safe to consume Greek yogurt past its expiry date, you must do a smell and texture check before consuming it. If it’s sour-smelling, watery, or lumpy, it’s best to dispose of it.

Storage Method Shelf Life
Refrigerated Greek yogurt (unopened) 2-3 weeks past the expiry date
Refrigerated Greek yogurt (opened) 7-10 days after opening
Frozen Greek yogurt 1-2 months

To maximize Greek yogurt’s lifespan, store it at the recommended temperature and conditions. Proper storage can help prolong the yogurt’s freshness and extend its shelf life.

Can you eat Greek yogurt after the expiration date?

Greek yogurt is a type of yogurt that has been strained to remove most of the whey, resulting in a thicker, creamier yogurt. Like any other food item, Greek yogurt also has a specific expiration date or ‘best by’ date mentioned on the packaging. It’s important to follow these dates to ensure the freshness and quality of the yogurt. However, there are instances where you might find an unopened container of Greek yogurt past its expiration date or might have forgotten about an opened one in the fridge. The question is, can you still eat Greek yogurt after the expiration date?

  • First and foremost, check the yogurt’s appearance and smell:
    • If the yogurt looks and smells normal, it’s most likely safe to eat even if it’s a few days past the expiration date.
    • If the yogurt looks or smells off, it’s best to discard it.
    • Moldy Greek yogurt should be discarded immediately to avoid any health issues.
  • Check the consistency of the yogurt by stirring it:
    • If the yogurt is lumpy or has any liquid separation, it’s past its prime and should be thrown away.
    • However, if the yogurt still has a smooth texture without any liquid separation, it can be consumed even if it’s past its expiration date.
  • Another factor to consider is the storage conditions of the yogurt:
    • If the yogurt has been stored at the recommended temperature (between 36-39°F or 2-4°C) throughout its shelf life, it’s more likely to be safe for consumption.
    • However, if the yogurt has been exposed to higher temperatures, it can spoil quickly.

In conclusion, consuming Greek yogurt after the expiration date depends on its appearance, smell, texture, and storage conditions. If the yogurt looks and smells normal, has a smooth texture, and has been stored properly, it’s likely still safe to eat. However, if there’s any sign of spoilage or the yogurt has been exposed to unsuitable storage conditions, it’s best to discard it to avoid any health risks.

Comparison between Greek yogurt and regular yogurt

Greek yogurt and regular yogurt may look similar, but they have distinct differences that affect their shelf life.

  • Greek yogurt is made by straining the whey from regular yogurt, resulting in a thicker and creamier texture. This process also removes some of the lactose and sugar, making it a healthier option.
  • Regular yogurt is made by fermenting milk with lactic acid bacteria, which gives it a tangy taste. It has a thinner consistency and contains more lactose and sugar than Greek yogurt.
  • When it comes to shelf life, Greek yogurt lasts longer than regular yogurt due to its lower moisture content. This makes it less prone to spoilage and bacterial growth.

However, it’s important to note that the shelf life of yogurt can also depend on the brand, storage conditions, and expiration date.

According to the USDA, open Greek yogurt can last up to two weeks in the refrigerator when stored properly. This means keeping it tightly sealed in its original container and avoiding cross-contamination with other foods.

Storage Tips for Yogurt Greek Yogurt Regular Yogurt
Refrigerate immediately after opening Up to 2 weeks Up to 1 week
Keep tightly sealed in original container
Avoid cross-contamination with other foods

Overall, both Greek yogurt and regular yogurt are nutritious and delicious options for a healthy diet. Understanding their differences and proper storage can help maximize their shelf life and prevent food waste.
