What that means
This keeps longer, but cold storage and clean handling still matter.
Use this as a planning window, then check the real-world spoilage signs below before eating.
Make Bacon Grease 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 in a sealed, airtight container or freezer bag. USDA FoodKeeper gives roughly 360 days at best quality; it stays safe longer but the texture drops off.
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.

Storage note
US mode uses the conservative end of the USDA FoodKeeper record (180 days, refrigerated). UK mode applies FSA chilling and label-first rules to the same record. The product label always wins when it gives a shorter period.
