FoodKeeper-based refrigerated planning reference
How long does half and half last in the fridge?
Well Stockd’s curated reference uses about 7 days refrigerated for half and half, 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 half and half turn on whether the package has been opened, so those windows are listed separately here.
- Unopened
- Up to the printed date, typically 1 to 2 weeks
- Opened or cut
- 7 to 10 days once opened
- Freezer
- Not recommended — freezing damages the texture beyond use.
- How to store it
- On a shelf, not the door. Freezing separates it, so it is not recommended.
How to tell if half and half 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.
- Curdling in hot coffee
- Sour smell
- Thickened or lumpy pour
How to use this window
A weekly kitchen review is frequent enough to surface this item before the catalog window passes.
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.
