How long does Greek yogurt last? And why the watery liquid on top is a good sign.
Yogurt is one of the longer-lasting dairy products in your fridge. The watery layer that gathers on top is not spoilage. It is whey, and it means your yogurt is doing exactly what it should.

Shelf life
How long does greek yogurt last?
Concrete numbers by storage condition. Use the longest viable option you have time for.
| Condition | Time | Note |
|---|---|---|
| Counter, room temperature | Under 2 hours | Live cultures notwithstanding, leaving yogurt out invites unwanted bacteria. |
| Fridge, unopened, on a shelf | Sell-by + 1-2 weeks | Sealed yogurt holds well past the printed date. |
| Fridge, opened | 5-7 days | Sealed tightly, on a shelf (not the door). |
| Freezer, sealed | 1-2 months | Texture turns grainy on thaw. Use for smoothies or baking. |
Storage
How to store greek yogurt for maximum freshness.
- 1
Store yogurt on a fridge shelf, not in the door. Like milk, yogurt keeps longer at stable, cold temperatures away from the door's temperature swings.
- 2
Keep yogurt in its original container. Decanting introduces air and bacteria. Seal tightly after each use.
- 3
The watery liquid on top is whey, a natural part of yogurt. You can stir it in for more creaminess, or pour it off if you prefer a thicker texture. It is not a sign of spoilage.
- 4
Sell-by dates are for retailers. Sealed Greek yogurt typically stays fresh one to two weeks past the sell-by date. Trust your senses over the printed date.
- 5
To freeze, leave the container sealed (with a little room for expansion if it is full) and use within two months. Texture grains on thaw, so frozen-then-thawed yogurt is best for smoothies, baking, or marinades.
Spoilage
How to tell if greek yogurt has gone bad.
Mold on the surface or under the lid (any color, fuzzy or otherwise).
Pink, yellow, or green discoloration in the yogurt itself.
A strong sour, rancid, or off smell beyond the normal tang.
Bloated container or popping seal when opened (indicates fermentation by unwanted bacteria).
A slimy or stringy texture when stirred.
