Sour cream will keep in your fridge for quite a long time, though eventually it may spoil. Over time it may lose some texture and flavor but is still safe to consume.

Spoilage often manifests itself in an unpleasant smell. If you detect an intensely pungent or sour scent, it may be time to throw out the sour cream product in question.


Sour cream is a key staple in many households, providing delicious creamy flavor for everything from nachos and baked potatoes to dips and salad dressings. But how long will sour cream keep in the refrigerator before going bad? This depends on various factors including temperature and whether its container has been sealed tightly enough; although it should last several weeks past its “best by” date if stored correctly.

Unopened sour cream should last two weeks in the fridge after its expiration date due to being protected from bacteria by being stored coldly; however, once opened and exposed to contaminants such as bacteria or mold it should be thrown out immediately as it will spoil much more quickly and should be discarded promptly.

A great way to identify whether sour cream has gone bad is its smell: If it emits an offensive, pungent aroma, it likely has gone off and should be discarded immediately. Taste testing it may also give an indicator as to its condition; any unusually strong or off-putting flavors should also be noted here. Furthermore, beware that improper storage conditions may allow mold and fungus to flourish; mold growth should always be monitored accordingly.

Store sour cream in an airtight container at or below room temperature and keep it at or below this point. If possible, push it back towards the back of the refrigerator so as to limit its exposure to light. Using clean utensils when handling sour cream can also help extend its shelf life; avoid double dipping or spooning from its own container, and always close with a clean lid when closing it up.

Refrigerating is another effective way of keeping sour cream fresh, although many food safety experts don’t advise it, as sour cream loses texture and flavor when frozen, rendering it less useful in recipes.

Although sour cream can last in your freezer for three months, it is still important to inspect it frequently and discard any that have a foul odor or are discolored. Also remember to consume within its expiration date in order to prevent potential health risks; any strong, unpleasant odor or thickened texture indicate it has likely gone bad and should be thrown out immediately; otherwise it should still be consumed as long as precautions are taken and it remains delicious meals ahead! By following these simple guidelines you’re guaranteed scrumptious meals ahead!


Sour cream is a versatile dairy product that can be used in numerous recipes. However, it is important to understand that like all food items, sour cream has an expiration date that must be observed and properly stored sour cream can last much longer than anticipated!

Refrigerating is the key to keeping sour cream fresh. Be sure to place it near the back or bottom of your refrigerator so as to limit air exposure; additionally, ensure it is tightly sealed within an airtight container for added protection from oxidation, one of the major sources of spoilage.

Once sour cream has gone bad, its appearance and aroma may change significantly. Tasting it will often reveal any off flavors present; if sour cream tastes off to you it might be best to throw it out immediately.

If sour cream is still sealed in its packaging, it may be kept up to two weeks past its expiration date without spoilage; this only indicates when it should be sold and consumed!

Be careful when purchasing dairy products past their expiration dates, particularly if they look and smell normal despite potentially harbouring bacteria that has developed inside. Most grocery stores will not sell expired dairy products.

Another way to make sour cream last longer and freshen it up faster is to freeze it, whether that means in its original packaging or an airtight freezer-safe container. When freezing sour cream directly in its original container, take extra steps such as wrapping it in aluminum foil or using a freezer bag so as to protect from potential contaminants, while leaving 1″ headspace so as to allow expansion when it thaws out.

When freezing sour cream, it is important to label its container with its date of creation – this allows you to keep track of how long it has been frozen and when to thaw it out. Storing frozen sour cream at its optimal level for six months ensures maximum freshness!

If your sour cream is about to expire, it is crucial that it is used up quickly or it will likely spoil before you can finish it. An exception could be if a specific recipe calls for it; otherwise it would be best to buy another container and use it for something else.


Sour cream is an incredibly versatile food item, capable of being used in numerous recipes and withstanding being stored correctly for the optimal shelf life. When left to spoil, however, it can become breeding grounds for bacteria and mold – rendering it unsafe to consume.

Refrigerating is the ideal way to store sour cream, where it will last two weeks after its expiration date. Be sure to inspect it periodically, particularly if you use it often, and discard any that becomes moldy or starts spoiling.

As soon as sour cream begins to have an offensive or pungent aroma, mold or discoloration may develop and slimy or thicker-than-normal consistency emerges; another telltale sign of spoilage would be its sharp and sour taste; therefore it should be discarded promptly.

After its expiration date has passed, it may still be safe to consume sour cream; however, only in small quantities and with extreme caution. Without the presence of lactic acid bacteria which helps digest food properly, consuming expired sour cream could lead to symptoms like bloating, gas and diarrhea; occasionally even stomach irritation could occur as a result.

If you have an abundance of sour cream near its expiration date, freezing it is an option. Just bear in mind that frozen sour cream won’t taste quite the same; its texture may even change once defrosted.

To properly store sour cream in the freezer, it is crucial that an inch is left at the top of its container to accommodate for its expansion when frozen. Furthermore, cover your sour cream with plastic wrap or paper towel prior to placing it into your freezer.

Eating expired sour cream should never be done, even if stored in the fridge, because it can serve as a breeding ground for bacteria and mold, potentially leading to food poisoning. Eating expired sour cream may be particularly hazardous for children who are particularly prone to illnesses related to expired food items; always exercise extreme caution with expired foods!
