What is the Shelf-Life of Cottage Cheese

Cottage Cheese is available with a best-by date mentioned on its label. But you must not confuse it with an expiry date. It lets the users know how long the Cottage Cheese can retain its freshness and quality.

Cottage Cheese producer, Kalona, confirms that their Cottage Cheese stays qualitative and fresh after the best-by date mentioned on the container.

The quality of Cottage Cheese starts degrading after the container is opened. The unopened container of Cottage Cheese lasts longer and stays fresh and flavorsome past its best-by date.

After opening the container, the Cottage Cheese stays fresh and keeps its quality for up to two weeks, as per Daisy Brand. The unopened container of Cottage Cheese lasts for ten days after its best-by date, provided that it is continuously refrigerated or stored in a freezer to keep it good for three months.

Unfortunately, Cottage Cheese is not a shelf-stable item, and hence it won’t last or keep its quality when stored in the pantry.
