What is the shelf life of sour cream?

Sour cream has a relatively short shelf life due to its high moisture content and the presence of bacteria. Here's an overview of its shelf life:

1. Unopened Sour Cream:

- Refrigerated: Unopened sour cream can last for about 2 to 3 weeks past its "sell-by" date if stored properly in the refrigerator at a temperature of 40°F (4°C) or below.

2. Opened Sour Cream:

- Refrigerated: Once opened, sour cream can last for about 7 to 10 days in the refrigerator. It's important to cover or reseal the container tightly after each use to prevent spoilage.

3. Freezing Sour Cream:

- Sour cream can be frozen to extend its shelf life further. It's recommended to freeze sour cream within a few days of purchase. Place it in an airtight container or a freezer-safe bag, leaving some headspace for expansion. Frozen sour cream can typically last for up to 2 to 3 months.

4. Signs of Spoilage:

- Spoiled sour cream may exhibit some noticeable changes, such as:

- Off odor: A sour or rancid smell is often a sign of spoilage.

- Texture changes: It may appear watery, grainy, or lumpy.

- Color changes: The color may become slightly yellow or gray.

It's always a good practice to check the "sell-by" or "best-before" date on the sour cream packaging and follow proper refrigeration guidelines to ensure its quality and safety.
