In this article, we’ll be looking at all these factors so you can understand how long your specific brand of sour cream will last in the refrigerator.
If you’re like most people, you’ve probably had a container of sour cream in your refrigerator for a while now, and you’re unsure whether it’s still good or not. Well, fret not! We’ll be answering all your questions to put your mind at ease. Knowing how long your sour cream lasts and how to store it correctly can save you a lot of money and time in the long-run, so let’s jump right into it!
What is sour cream and how is it made?
Sour cream is a dairy product that is commonly used as a topping for various dishes, such as baked potato, nachos, and tacos. It is made by fermenting cream with lactic acid bacteria, which gives it its distinctive tangy flavor and thicker texture compared to regular cream.
To make sour cream, manufacturers usually use heavy cream or a mixture of light cream and milk. The cream is pasteurized to kill any harmful bacteria and then cooled down to room temperature. Afterwards, a starter culture of lactic acid bacteria, such as Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus, is added to the cream.
The mixture is then left to ferment for several hours, allowing the bacteria to convert the lactose in the cream into lactic acid. This process thickens the cream and gives it its characteristic tangy taste. Once the desired thickness and flavor are achieved, the sour cream is refrigerated to stop the fermentation process and maintain its freshness.
What are the Ingredients of Sour Cream?
Before we dive into the question of how long sour cream lasts in the refrigerator, let’s take a closer look at what it’s made of. Sour cream is a dairy product that is made by fermenting regular cream with lactic acid bacteria. The bacteria convert the lactose in the cream into lactic acid, which thickens and sours the cream.
- Regular cream – the main ingredient in sour cream, which is high in fat content.
- Lactic acid bacteria – the type of bacteria used to ferment the cream, which creates the sour taste and thick texture.
- Stabilizers – some manufacturers add stabilizers like gelatin or carrageenan to thicken the sour cream and prevent it from separating.
Many types of sour cream are available in the market today, so be sure to read the label carefully and check for any additives or preservatives that may affect the shelf life of the product.
How long is the shelf life of unopened sour cream?
As a dairy product, sour cream has a relatively short shelf life. However, unopened sour cream can last longer than opened ones since it is protected from outside factors that can promote spoilage.
- The average shelf life of unopened sour cream is two to three weeks past the expiration date printed on the container. This estimation is assuming that the container is properly sealed, stored in optimal conditions, and has not been opened.
- It is crucial to check the sell-by or use-by date of the sour cream before purchasing it. The closer it is to the expiration date, the shorter the shelf life it will have once you bring it home.
- If you are unsure about the freshness of the unopened sour cream, you can perform the smell and taste test. If it smells or tastes sour, bitter, or rancid, it means that the sour cream has gone bad and should not be consumed.
Factors Affecting the Shelf Life of Unopened Sour Cream
Several factors can affect the shelf life of unopened sour cream:
- Storage temperature: Sour cream should be stored at a temperature between 34 and 40 degrees Fahrenheit, which is the ideal temperature range for dairy products. The higher the temperature, the faster sour cream will spoil.
- Light: Exposure to light can cause the dairy product to break down. It is best to store unopened sour cream in a dark and cool place, away from direct sunlight.
- Microbial activity: Microbes can thrive in the container of sour cream, which can promote spoilage. For this reason, it is important to ensure that the container is properly sealed to minimize the microbial growth.
How to Store Unopened Sour Cream
Following these guidelines will help to extend the shelf life of unopened sour cream:
- Store unopened sour cream in the fridge, preferably on the middle shelf where the temperature is more consistent and lower than the door shelf.
- Ensure the container is properly sealed and that the lid is tight to prevent air, light, and moisture from entering the container.
- Keep sour cream away from food with strong odors; sour cream can easily absorb flavors from its surroundings, and this can affect its taste and quality.
In conclusion, unopened sour cream can last up to three weeks past the expiration date on the container if it is properly stored and unopened. When you open the container, it is essential to consume the sour cream within a week to prevent spoilage and avoid foodborne illnesses.
Should you check the expiration date of sour cream before buying it?
When grocery shopping, checking the expiration date of the products we buy has become a habit. But do we really need to check the expiration date of sour cream before buying it? The answer is yes.
- The freshness of the sour cream affects its overall quality. When it starts to spoil, the sour cream will start to produce bacteria and yeast that will cause it to have a sour taste and a thick texture.
- Checking the expiration date is also essential to ensure that you are getting your money’s worth. Imagine buying sour cream that will expire in a day or two, you would need to consume it quickly, and it might turn bad before you get the chance to use it again.
- Expired sour cream can cause foodborne illnesses. Eating expired sour cream may cause symptoms such as vomiting, diarrhea, and stomach ache. Thus, knowing how long it lasts in the fridge is essential to prevent any potential health risks.
Now, how long does sour cream last in the refrigerator?
| Refrigerator storage (40°F or below) | Sour cream type | Duration |
|---|---|---|
| Unopened container | Regular sour cream | Two weeks after the expiration date |
| Unopened container | Low-fat sour cream | Two weeks after the expiration date |
| Opened container | Regular sour cream | One to two weeks after opening |
| Opened container | Low-fat sour cream | One to two weeks after opening |
The table shows the estimated duration of sour cream in the refrigerator. It is essential to note that proper storage is also necessary to ensure the freshness and quality of the sour cream. Make sure to place it in an airtight container or resealable bag to prevent air from entering. Store it in the coldest part of the fridge, typically at the back of the lower shelf.
Checking the expiration date of sour cream before purchasing is a vital practice to ensure that you get to enjoy your favorite dips, sauces, and desserts. It is also best to take note of the storage instructions to keep its freshness and quality.
What are the signs of spoiled sour cream?
If you’re not sure whether your sour cream has gone bad or not, here are some signs to look out for:
- An off smell – sour cream should have a mild, slightly tangy scent. If it smells funky or unpleasant in any way, it may have gone bad.
- Mold – if you see any mold growth on the surface of your sour cream, it’s definitely time to throw it out.
- Discoloration – if your sour cream has turned a yellowish or grayish color, it’s probably spoiled.
- Texture – fresh sour cream should be smooth and creamy, with no lumps or curdling. If you notice any separation or graininess, it’s a sign that the sour cream has spoiled.
- Sour taste – while sour cream is supposed to be slightly tangy, really sour or bitter-tasting sour cream is a clear sign that it’s gone bad.
If your sour cream shows any of the above signs, it’s time to toss it and buy a fresh container.
Can Sour Cream be Frozen for Storage?
Sour cream is a versatile dairy product that is commonly used in cooking and baking to add creaminess, tartness, and richness to dishes. Like most dairy products, sour cream has a limited shelf life and needs to be stored properly to maintain its quality and freshness.
One of the questions that many people often ask about sour cream is whether it can be frozen for storage. The answer is yes. Sour cream can be frozen for storage, but it is important to follow some simple guidelines to ensure that the sour cream retains its flavor and texture.
- The first step in freezing sour cream is to make sure that it is fresh. Sour cream that is close to its expiration date or has exceeded it should not be frozen.
- Before freezing, transfer the sour cream to a freezer-safe container with an airtight lid. This will help to prevent freezer burn and ice crystals from forming on the sour cream.
- Label the container with the date and use within six months.
- To thaw, remove the container from the freezer and let it sit in the refrigerator overnight.
- Alternatively, you can thaw sour cream quickly by placing the container in a bowl of cold water. Change the water every 30 minutes until the sour cream is thawed.
- Do not try to hasten the thawing process by microwaving the sour cream or leaving it at room temperature as this can affect its texture and flavor.
It is important to note that sour cream that has been frozen may separate and become watery upon thawing. However, this does not necessarily mean that the sour cream has gone bad. To restore the texture, simply stir the sour cream vigorously until it becomes smooth and creamy again.
Overall, freezing sour cream is a great way to extend its shelf life and reduce food waste. By following these simple guidelines, you can freeze sour cream safely and ensure that it remains fresh and usable for up to six months.
| Freezing Guidelines for Sour Cream |
|---|
| Make sure that the sour cream is fresh and not close to its expiration date |
| Transfer sour cream to a freezer-safe container with an airtight lid |
| Label the container with the date and use within six months |
| To thaw, remove from freezer and let it sit in the refrigerator overnight, or place in a bowl of cold water |

It is important to note that the shelf life of sour cream may vary depending on several factors such as storage conditions, packaging, and brand. Always use your best judgment and inspect the sour cream’s texture, color, and smell before consuming.
Can you use expired sour cream in cooking or baking?
Now that we know how long sour cream lasts in the refrigerator, the next question is can you use expired sour cream in cooking or baking? The answer is not straightforward as it depends on how expired the sour cream is and the type of recipe you’re making.
First, let’s define what we mean by expired sour cream. Generally, sour cream is safe to eat up to a week after its sell-by date if it has been stored properly, as discussed earlier. However, after a week or if it has been stored improperly (left out at room temperature for more than two hours), the sour cream will spoil, and the moldy or rancid odor and flavor will appear. Using such sour cream in cooking or baking is not recommended, as it can make your dish taste and smell unpleasant, or even make you sick.
If the sour cream is just slightly past its sell-by date (1-2 days), you can still use it in cooking or baking. The acidity in the sour cream acts as a natural preservative, which means it can still be safe to consume. However, it’s essential to check for any signs of spoilage, such as mold growth, a sour or rancid smell, or changes in texture. If the sour cream looks or smells suspicious, discard it immediately.
- If you’re making a dish that requires baking or cooking the sour cream, such as sour cream cake, biscuits, or casserole, using slightly expired sour cream should not pose any health risks as the cooking process will kill any harmful bacteria that may be present. However, keep in mind that the taste and texture of the dish may be affected.
- If you’re making a dish that requires uncooked sour cream, such as dips, dressings, or sauces, it’s best to use fresh sour cream to avoid any risk of food poisoning. Alternatively, you can use Greek yogurt or buttermilk as a substitute for sour cream, which has a similar tangy flavor and texture.
- It’s always better to err on the side of caution when it comes to using expired sour cream. If you’re unsure of its freshness or if it looks and smells off, it’s best to discard it and use fresh sour cream instead.
In summary, using expired sour cream in cooking or baking depends on how far past its sell-by date it is and the recipe you’re making. While using slightly expired sour cream may be safe and does not pose any health risks, it’s always better to use fresh sour cream to ensure the best taste and quality of your dish.
How long does homemade sour cream last?
In general, homemade sour cream lasts for about two weeks in the refrigerator. However, this can vary depending on factors such as the freshness of the cream and the temperature of your refrigerator. Here are some more details to keep in mind:
- When making sour cream at home, be sure to use fresh cream that has not yet reached its expiration date. Using old cream can lead to sour cream that spoils faster.
- It’s also important to keep the sour cream refrigerated at all times. Leaving it out for extended periods of time can cause harmful bacteria to grow.
- If you notice any signs of spoilage, such as an unusual smell or mold growth, it’s best to discard the entire batch of sour cream.
If you’re concerned about the longevity of your homemade sour cream, try making smaller batches. This can help ensure that you’re using the freshest cream and that it’s eaten before it spoils.
Here is a table outlining the general shelf life of sour cream:
| Type of Sour Cream | Refrigerator Shelf Life |
|---|---|
| Store-bought, unopened | 2-3 weeks past printed date |
| Store-bought, opened | Up to 2 weeks |
| Homemade | About 2 weeks |
Remember to always use your best judgement when consuming food. If you’re unsure about the safety or freshness of your sour cream, it’s better to err on the side of caution and throw it out.
Is it safe to eat sour cream past its expiration date if it looks and smells okay?
It is not recommended to consume sour cream past its expiration date, even if it looks and smells okay. The expiration date is put on the package to ensure food safety and quality. After the expiration date, the sour cream may contain harmful bacteria that can cause foodborne illnesses.
- Always check the expiration date before consuming sour cream.
- If the expiration date has passed, it is better to throw the sour cream away.
- If the sour cream has been stored properly and does not show any signs of spoilage, it may still be safe to consume within a few days after the expiration date, but the risk of consuming harmful bacteria increases.
It is important to note that the “sniff test” is not an accurate indicator of whether or not sour cream is safe to eat. Harmful bacteria that cause foodborne illnesses do not always produce a noticeable odor or flavor. Therefore, it is best to err on the side of caution and dispose of sour cream that has passed its expiration date.
If you are unsure about the safety of sour cream, always consult with a healthcare professional.
| Signs of spoiled sour cream: | Signs of safe sour cream: |
|---|---|
| Off-color or yellowing | Bright white color |
| Off-smell or rancid odor | Faint tangy smell |
| Mold or discoloration | Smooth and even consistency |
| Curdling or separation | Creamy texture with no lumps |
If your sour cream shows any of the signs of spoilage listed in the table above, it is best to discard it immediately.
