Milk is one of the most-wasted items in the fridge — partly because it's bought often, and partly because half a carton hides behind everything else until it turns. The short answer: opened milk keeps about 3-4 days, and unopened milk lasts to its date and sometimes a touch beyond if it's been kept properly cold. But how you store it makes a real difference, and your nose is the final word. Here's the detail.
- Opened milk: about 3-4 days in the fridge.
- Unopened: until its date, sometimes slightly past if kept cold — go by smell.
- Store it on a cold shelf, not the door — the door is the warmest part.
- Freeze it for up to ~3 months if you won't use it in time.
How long milk keeps
Once opened, milk is best used within 3-4 days, kept in the fridge at 0-5°C as the UK Food Standards Agency recommends. Unopened, it lasts until its printed date, and if it's been kept consistently cold it can be fine a little beyond — depending on whether that date is a use-by or best-before. A quick reference:
Whole, semi-skimmed and skimmed milk behave similarly. Lactose-free and plant milks vary, so check the carton — many last a few days once opened too.
Date labels: use-by vs best-before
Whether you can use milk past its date depends entirely on which label it carries. A use-by date is about safety — follow it. A best-before date is about quality, so milk is often fine for a short time afterward if it's been kept cold and smells and tastes normal. The difference between best-before and use-by is worth knowing, because confusing the two is a major cause of perfectly good milk going down the sink.
How to make milk last longer
Small storage tweaks buy you days. The biggest one: keep milk on a cold middle or lower shelf, never in the door — the door warms up every time you open the fridge, which is exactly why door-stored milk turns first. A few more:
- Put it back promptly. Don't leave milk out on the counter while you have breakfast; the warmth shortens its life.
- Keep the fridge at 0-5°C. Warmer than that and milk sours faster — check with a thermometer.
- Freeze the surplus. If you've over-bought, freeze it before the date for up to ~3 months (pour a little out first for expansion). See can you freeze milk.
How to tell if milk has gone off
Milk is one of the easiest foods to judge — your senses beat the date every time:
- Smell: a sour, sharp smell is the clearest sign it's turned.
- Texture: lumps, curdling or thickening mean it's off.
- Taste: if it smells fine but you're unsure, a tiny sip tells you — sour is unmistakable.
Scan your receipt and Fango adds your milk with an estimated date, then reminds you before it's due. The widget shows what's expiring next — so the half-used carton gets used, not poured away.

Milk waste is almost always a timing problem, not a storage one — the carton was fine, you just forgot it was open. A reminder a day before it's due closes that gap. For more, see how long food lasts in the fridge and how long yogurt lasts.
Frequently Asked Questions
How long does milk last in the fridge?
Opened milk generally keeps about 3-4 days in the fridge, and unopened milk lasts until its date and sometimes a little beyond if kept properly cold. Storage matters a lot: milk lasts longer on a cold middle shelf than in the door. Always go by smell and taste as well as the date — sour milk is obvious.
Can you drink milk after its date?
It depends on the date type. If it's a use-by date, follow it for safety. If it's a best-before date, milk is often fine for a short time after if it's been kept cold and smells and tastes normal. When in doubt, smell it — milk that's turned has an unmistakable sour smell.
Can you freeze milk?
Yes. Milk freezes well for up to about three months. Pour a little out first to leave room for expansion, freeze it before the date, and thaw it in the fridge. It may separate slightly — just shake it well. Frozen-then-thawed milk is best for cooking, tea or coffee rather than drinking straight.
How does Fango help you use milk in time?
Scan your receipt and Fango adds your milk with an estimated date, then reminds you before it's due so it doesn't turn at the back of the fridge. The home-screen widget shows what's expiring next, so the half-used carton gets used rather than poured away.
