Unopened yogurt usually lasts 1 to 2 weeks past its printed date when kept refrigerated, and about a week once opened. The date is a quality guide rather than a strict cutoff. Some liquid on top is normal whey and can be stirred in, but discard yogurt that smells sour and sharp, looks moldy, or is bloated.
Yogurt: 1 to 2 weeks past its date unopened, about a week opened, kept cold. Toss it if moldy or off-smelling.
How Long It Keeps
- Unopened: often 1 to 2 weeks beyond the printed date, refrigerated.
- Opened: about one week, sealed and cold.
- A little watery whey on top is normal, just stir it in.
- Discard yogurt that is moldy, bloated, or smells unusually sour.
Signs It Has Gone Bad
Yogurt is already fermented, so it lasts a while, but off signs include mold, a puffy container, a curdled or lumpy texture beyond normal, and a sharp, unpleasant smell. Keep it in the coldest part of the fridge. Store opened tubs sealed in a container, and note you can also use yogurt as a sour cream substitute.
Frequently Asked Questions
Can you eat yogurt past its expiration date?
Often yes. Unopened yogurt is usually good for 1 to 2 weeks past its date if refrigerated. Check for mold, off smells or a bloated container first.
Is the liquid on top of yogurt bad?
No. That liquid is whey, a normal part of yogurt. Just stir it back in; it is a sign of separation, not spoilage.
