FoodKeeper-based refrigerated planning reference
How long does sour cream last in the fridge?
Well Stockd’s curated reference uses about 14 days refrigerated for sour cream, assuming a refrigerator kept at 40°F (4°C) or below. This is a planning estimate drawn from the app’s FoodKeeper/FSIS-based catalog, not a package date or a safety guarantee.

Unopened, opened, and frozen
The single fridge number above is a planning figure. Most of the questions people actually ask about sour cream turn on whether the package has been opened, so those windows are listed separately here.
- Unopened
- Up to the printed date, typically 2 to 3 weeks
- Opened or cut
- 1 to 2 weeks once opened
- Freezer
- Not recommended — freezing damages the texture beyond use.
- How to store it
- Airtight on a shelf. Freezing splits it, so it is not recommended.
How to tell if sour cream has gone bad
Dates are estimates; these are the checks that actually decide it. When more than one of these is present, throw it out rather than tasting to find out.
- Any mould
- Sharp sour smell beyond its normal tang
- Watery separation with discolouration
- Yellowing
How to use this window
Record when the item entered your kitchen and check it during your regular weekly inventory review.
Well Stockd does not know when this food was harvested, packed, purchased, opened, prepared, or moved between storage locations. Record the relevant opened, prepared, or refrigerated date, follow package directions, keep your refrigerator at 40°F or below, and use the official item listing when food safety is in question.
Primary sources and limits
The repository catalog identifies USDA FoodKeeper and FSIS typical refrigerated storage guidance as its source. FoodKeeper explains that storage times are guidelines and that actual quality varies with growing, handling, distribution, and storage conditions.
