How long is chocolate milk good after the sell by date?

The sell-by date on chocolate milk is not an indicator of how long it is safe to drink. It is simply the date by which the manufacturer recommends selling the product for peak quality and flavor. Chocolate milk can safely be consumed after the sell-by date, but it may begin to lose its flavor and freshness over time. It is important to store chocolate milk properly in a cool, dark place to extend its shelf life.
