Shelf life of yogurt at a glance
| Storage | Unopened | Opened |
|---|---|---|
| Fridge | 1 week | – |
| Freezer | 1 month | – |
Keep the container closed on the middle shelf of the fridge and only use a clean spoon. Watery whey on top can be stirred back in; throw it out if there is mold, a domed lid or a fizzy, yeasty taste. Yogurt that has been frozen turns slightly grainy and is best used in smoothies or baking.
Does yogurt go bad?
Food past its date has not necessarily gone bad. The times on this page are guideline values for food stored properly. In the US, date labels are not required by federal law (infant formula is the exception), and most of them describe quality, not safety. A "Best if Used By" date is not an expiration date, and many products are still fine after it. A "Sell By" date is meant for the store, not for you. Look at the food and smell it before you taste a little. Mold, an off smell or a bulging can or lid means it goes in the trash. Take a "Use By" date on perishables such as meat, fish, deli meats and dairy seriously: eat or freeze them by that date.
