The humble tub of sour cream, a staple in many a kitchen, is often taken for granted. We use it to add a tangy zip to our baked goods, soups, and sauces, but how often do we stop to think about its shelf life? The answer is crucial, as sour cream can spoil quickly if not stored properly, leading to a batch of spoiled food and a ruined recipe. In this article, we’ll delve into the world of sour cream storage, exploring how long it will last in the refrigerator and what factors can affect its longevity.
Understanding Sour Cream’s Shelf Life
Sour cream is a dairy product made from cream that has been fermented with lactic acid bacteria. This fermentation process gives sour cream its characteristic tangy flavor and thick, creamy texture. However, it also makes it more prone to spoilage than other dairy products.
The shelf life of sour cream is influenced by several factors, including its storage conditions, handling, and the type of sour cream being used. Generally, sour cream can last anywhere from a few days to several weeks when stored in the refrigerator. But how can you be sure it’s still good to use?
Factors Affecting Sour Cream’s Shelf Life
Several factors can impact the shelf life of sour cream, including:
| Factor | Description |
|---|---|
| Storage Temperature | Sour cream should be stored in the refrigerator at a temperature of 40°F (4°C) or below. |
| Handling | Sour cream should be handled carefully to prevent contamination and spoilage. |
| Type of Sour Cream | Homemade sour cream may have a shorter shelf life than store-bought sour cream, which has been pasteurized and has a longer shelf life. |
| Expiration Date | Sour cream should be consumed before the expiration date printed on the container. |
How Long Will Sour Cream Last in the Refrigerator?
The shelf life of sour cream in the refrigerator can vary depending on the factors mentioned above. Generally, sour cream can last:
- Homemade sour cream: 3 to 5 days
- Store-bought sour cream: 7 to 10 days
- Urgent care sour cream: 1 to 3 days
It’s essential to check the sour cream regularly for signs of spoilage, such as an off smell, slimy texture, or mold growth. If you notice any of these signs, it’s best to err on the side of caution and discard the sour cream.

To ensure your sour cream lasts as long as possible, follow these storage tips:
