The short answer: Yogurt keeps about 1 to 2 weeks in the fridge, and up to the date on the pot if unopened.
How long yogurt lasts
- Fridge: About 1 to 2 weeks
- Freezer: 1 to 2 months; the texture changes, so use it in smoothies and baking
How to tell yogurt has gone off
- Mold of any colour
- A strongly sour smell beyond its normal tang
- A lot of watery liquid with an off smell (a little clear liquid on top is normal)
How to make it last longer
- Use a clean spoon each time.
- Store it upside down to stop liquid pooling, if the pot allows.
- Freeze in an ice-cube tray for smoothies.
Common questions
Is the liquid on top of yogurt bad?
A little clear liquid is whey and is normal. Stir it back in. Throw the pot away if it also smells off or has mold.
General guidance only. These times are for food bought fresh and kept at 40°F (4°C) in the fridge or 0°F (-18°C) in the freezer. Your own fridge, the packaging and the state of the food always come first, and when in doubt, throw it out. The official US chart is on FoodSafety.gov.
