What that means
Plan to finish it this week.
Use this as a planning window, then check the real-world spoilage signs below before eating.
Make Yogurt last the full window
Do
- Refrigerate promptly after each use, at 5°C / 40°F or below.
- Use a clean utensil every time you take a portion.
- Keep it sealed — the original lid or an airtight container.
- Skip the freezer for this one — Not suitable for freezing as texture and flavor quality will be significantly compromised.
Don't
- Leave it out on the counter while cooking or serving.
- Double-dip or return unused portions to the container.
- Store it in the fridge door if you open the fridge often — it is the warmest spot.
- Taste it to "test" safety. If in doubt, throw it out.

Where this guidance comes from
The Yogurt window blends official US food-safety guidance with typical manufacturer opened-storage instructions. The label on your specific product always wins if it is stricter.
Storage note
Both the UK and US generally recommend consuming opened yogurt within a week, though refrigeration is critical for both regions.
Check before eating
Look
Mold growth (fuzzy patches) or visible separation of whey from the cultured solids are common signs of spoilage.
Smell
A sour, yeasty, or distinctly acidic odor that is stronger than the normal yogurt tang indicates bacterial overgrowth.
Texture
The yogurt may become overly liquid, grainy, or develop a slimy, curdled consistency.
Freezing
No. Not suitable for freezing as texture and flavor quality will be significantly compromised.

How long does Yogurt last after opening?
When stored correctly according to guidelines, it generally lasts around 7 days. Always rely on your senses if it looks or smells off.
How can I tell if Yogurt has gone bad?
