How Long Does Sour Cream Last in the Refrigerator?
Sour cream is a staple ingredient in many kitchens, known for its creamy texture and tangy flavor. Whether used as a topping, in baking, or in savory dishes, sour cream elevates meals with its unique profile. However, like all perishable items, it has a limited shelf life. Understanding how long sour cream lasts in the refrigerator can prevent food waste and ensure safety in consumption.
Factors Affecting Sour Cream's Shelf Life
Storage Conditions
The shelf life of sour cream depends largely on how it is stored. It should always be kept refrigerated at a temperature of 40°F (4°C) or below. Keeping it in the coldest part of the refrigerator, away from the door where temperatures fluctuate, will help extend its usability.
Packaging Integrity
The original packaging plays a significant role in preserving sour cream's freshness. Ensure the lid is tightly sealed after each use. This prevents contamination and exposure to air, which can lead to spoilage.
Shelf Life of Sour Cream
Unopened Sour Cream
Unopened sour cream typically lasts about 1 to 2 weeks past its printed expiration date, provided it has been stored properly. Here is a quick guide:
| Sour Cream State | Refrigerator Life (Past Expiration Date) |
|---|---|
| Unopened | 1 to 2 Weeks |
Opened Sour Cream
Once opened, sour cream generally lasts about 7 to 10 days. To maintain freshness, avoid double-dipping with utensils and close the lid tightly after each use.

Signs of Spoiled Sour Cream
Visual Cues
Indicators of spoilage include the presence of mold, discoloration, or separation of liquid. If the sour cream appears yellowish or has mold, it should be discarded immediately.
Smell and Taste
Sour cream should have a mild tangy aroma. A strong, off smell or a bitter taste indicates that the product is spoiled and should not be consumed.
Best Practices for Prolonging Shelf Life
Refrigeration Tips
- Store Properly: Always store sour cream in its original container. If transferring to another container, ensure it is airtight.
- Avoid Cross-Contamination: Use a clean spoon or utensil each time you scoop out sour cream to prevent bacteria from spoiling the entire container.
Smart Usage
- First In, First Out: Adopt the FIFO method by consuming older products before opening a new container.
- Check Dates Regularly: Regularly monitor expiration dates and consume the oldest sour cream first.
Conclusion
Knowing how long sour cream lasts in the refrigerator helps in planning meal preparations, reducing food waste, and ensuring that your recipes are both delightful and safe. By storing sour cream correctly and being aware of the signs of spoilage, you can keep it fresh for as long as possible. Whether unopened or opened, maintaining the right conditions will ensure your sour cream remains a staple in your culinary endeavors.
