How long does milk last?

Updated 3 July 2026 · 3 min read

Opened milk keeps about 4–7 days in the fridge. Unopened, go by the use-by date on the bottle — and you can freeze milk for around a month.

How to make milk last longer

Store it on a shelf near the back — the coldest part — not in the door, where it’s warmest and the temperature swings every time you open the fridge. Keep the lid on tight and put it straight back after use.

How to tell if milk has gone off

“Use by” is a safety date — if it smells sour, don’t risk it.

Use it up before it turns

Close to the date? Use it in porridge, pancakes, a white sauce, or a smoothie — or freeze it. Not sure what to make? Ask What’s in my Fridge and it’ll suggest dinners from what you’ve got. See also: the full fridge storage chart.
