The refrigerator is a staple in every household, providing a cool and safe environment for our food to stay fresh for a longer period. Among the numerous items we store in our fridge, sour cream is a popular condiment that adds a tangy and creamy flavor to various dishes. However, when it comes to the shelf life of sour cream, many of us are left wondering how long it can be stored in the refrigerator. In this article, we will delve into the world of sour cream and explore the answer to this pressing question.
The Importance of Proper Storage
Sour cream is a dairy product that is highly perishable, meaning it can spoil quickly if not stored properly. When you purchase sour cream, it is essential to check the expiration date or the “use by” date, which is usually printed on the packaging. However, even if the sour cream is within its expiration date, it can still go bad if it is not stored correctly.
Factors Affecting Shelf Life
Several factors can affect the shelf life of sour cream, including:
- Temperature: Sour cream should be stored at a consistent refrigerator temperature of 40°F (4°C) or below.
- Handling: Avoid exposing sour cream to heat, light, or physical stress, which can cause it to spoil faster.
- Contamination: Keep sour cream away from strong-smelling foods, as it can absorb odors easily.
- Expiration Date: Check the expiration date or “use by” date on the packaging.
How Long Does Sour Cream Last in the Refrigerator?
The shelf life of sour cream in the refrigerator depends on several factors, including the type of sour cream, storage conditions, and handling practices. Generally, sour cream can last for:
Homemade Sour Cream
Homemade sour cream, which is made by fermenting heavy cream with bacterial cultures, typically has a shorter shelf life than store-bought sour cream. It can last for:
| Storage Conditions | Shelf Life |
|---|---|
| Refrigerated at 40°F (4°C) | 3-5 days |
| Refrigerated at 50°F (10°C) | 2-3 days |
Store-Bought Sour Cream
Store-bought sour cream, which is pasteurized and packaged in airtight containers, typically has a longer shelf life than homemade sour cream. It can last for:
| Storage Conditions | Shelf Life |

| Refrigerated at 50°F (10°C) | 5-7 days |
Signs of Spoilage
Even if sour cream is stored properly, it can still spoil if not checked regularly. Here are some signs of spoilage to look out for:
- Off smell: Sour cream that has gone bad often emits a strong, unpleasant odor.
- Slime or mold: Check for any visible signs of slime or mold on the surface of the sour cream.
- Sluggish texture: Fresh sour cream should have a smooth and creamy texture. If it has become watery or grainy, it may be spoiled.
- Expiration date: Check the expiration date or “use by” date on the packaging.
What to Do with Expired Sour Cream
If you notice any signs of spoilage or the sour cream has exceeded its expiration date, it is best to discard it. Here are some tips on what to do with expired sour cream:
- Discard it: If the sour cream has gone bad, it is best to discard it to avoid foodborne illness.
- Use it in cooking: Expired sour cream can still be used in cooking, but it may not have the same flavor and texture as fresh sour cream.
- Freeze it: You can freeze sour cream for up to 3 months, but it is best to use it within a month for optimal flavor and texture.
