How Long Does Sour Cream Last in the Refrigerator?

Sour cream is a versatile and delicious dairy product that can enhance the flavor and texture of many dishes. Whether you use it as a topping for baked potatoes, a key ingredient in dips and sauces, or as a component of baked goods, sour cream adds a rich and tangy flavor to your favorite recipes. But, like all dairy products, sour cream has a limited shelf life, and it's important to store it properly to ensure its quality and safety. In this blog post, we will discuss how long sour cream lasts in the refrigerator, as well as provide tips on storage and safety.

Factors Affecting the Shelf Life of Sour Cream

Several factors can influence how long sour cream will last in the refrigerator:

1. Packaging

The type of packaging can impact the shelf life of sour cream. Sour cream that comes in a resealable container or tub will generally last longer than sour cream in a foil or paper container.

2. Temperature

Maintaining the proper temperature in your refrigerator is crucial to extending the shelf life of sour cream. The ideal temperature for storing sour cream is between 35-40°F (1.6-4.4°C).

3. Contamination

Cross-contamination can introduce harmful bacteria to sour cream, reducing its shelf life. Always use clean utensils when scooping out sour cream and avoid double-dipping to prevent contamination.

4. Freshness

The fresher the sour cream when you purchase it, the longer it is likely to last in the refrigerator. Check the expiration date on the packaging before buying sour cream.

How Long Does Sour Cream Last in the Refrigerator?

On average, sour cream can last in the refrigerator for about 2-3 weeks after opening, if stored properly. Unopened sour cream can last for 1-2 weeks past the sell-by date. However, these are just general guidelines, and the actual shelf life of sour cream can vary based on the factors mentioned above.

Signs that Sour Cream Has Gone Bad

It's important to be able to recognize the signs that sour cream has gone bad. Some indicators that sour cream is no longer safe to eat include:
