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 Lemon Juice 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 — Pour into airtight containers or ice cube trays and freeze until solid.
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 Lemon Juice 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
The US generally allows a slightly longer window for fresh lemon juice compared to UK guidelines, though refrigeration is critical in both regions.

Windows are conservative planning ranges built from public UK FSA and US FDA/USDA guidance, then tightened when typical manufacturer labels run shorter.
Cold storage, clean utensils, and label-first handling win over memory or social-media myths.
