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.
- Freeze it before the window closes if you will not finish it — Freeze promptly in a sealed freezer-safe container; thaw in the refrigerator.
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 UK food-safety guidance with typical manufacturer opened-storage instructions. The label on your specific product always wins if it is stricter.
Storage note
US mode uses the conservative end of the USDA FoodKeeper range. UK mode applies FSA chilling and label-first rules to the exact USDA FoodKeeper record; the product label wins when it is shorter.
