Understanding Sour Cream’s Shelf Life

The shelf life of sour cream can vary depending on several factors, including its quality, storage conditions, and whether it has been opened or unopened.

How Long Does Unopened Sour Cream Last?

Unopened sour cream typically has a longer shelf life compared to opened containers. It can last for about two to three weeks past the printed expiration date if stored properly in the refrigerator.

However, it’s crucial to rely on your senses to determine its freshness. If you notice any signs of spoilage, such as an unpleasant odor, mold, or separation, it’s best to discard the sour cream.

Proper Storage of Sour Cream

To maximize the shelf life of sour cream and maintain its quality, consider the following storage tips:

Refrigeration: Sour cream should always be stored in the refrigerator, ideally at a temperature below 40°F (4°C). Make sure to keep the container tightly sealed to prevent air and moisture from entering, which can accelerate spoilage.

Avoid Temperature Fluctuations: Fluctuations in temperature can negatively impact sour cream’s freshness. Avoid placing it near the refrigerator door or in areas where the temperature varies, such as near the stove or oven.

Signs of Spoiled Sour Cream

Before consuming sour cream, it’s important to check for any signs of spoilage. Some common indicators of spoiled sour cream include:

Mold: If you notice any green, black, or fuzzy mold growth on the surface, discard the entire container.

Off Smell: Sour cream should have a mild, tangy aroma. If it smells rancid, sour, or foul, it is an indication that it has gone bad.

Texture Changes: Sour cream that has separated or developed a watery consistency is no longer suitable for consumption.

Freezing Sour Cream

While sour cream can be frozen, its texture may change once thawed, resulting in a grainy or watery consistency. It is generally not recommended to freeze sour cream unless you plan to use it as an ingredient in cooked dishes, such as sauces or casseroles. When freezing sour cream, transfer it to an airtight container, leaving some room for expansion, and use it within three months for the best quality.


In conclusion, if your question is how long does sour cream last then its answer is, the shelf life of sour cream depends on whether it is unopened or opened.
