Shelf Life Of Sour Cream. When it comes to shelf life of source cream, there are many different opinions. Letâs start with the safest estimates. Most sour creams have a âsell-byâ date. As long as the package stays unopened, the dairy product should be fine for about 2 weeks after that date. If it has an expiration date (instead of a âsell-byâ date), add a week to the expiration date. Once the package is opened, its contents should be fine for 1 to 2 weeks. Of course shelf life of sour milk depends on how and how long (if weâre talking about opened container of sour milk) it has been stored.
