Short answer: keep milk, paneer and dahi in the fridge at 4°C or colder, and don't leave them out for more than two hours (one hour on a very hot day). Refrigerate pouch milk as soon as it arrives and use it by the date on the pack. Store paneer in an airtight container or submerged in water you change daily, and keep dahi covered. Paneer can be frozen, though its texture changes.
Dairy is some of the most perishable food in an Indian kitchen, and Pune and Mumbai summers, monsoon humidity and the occasional power cut don't help. This guide covers how to store each product, how long it keeps, and the signs that it's time to throw it out.
One rule applies throughout: the use-by date on the pack comes first. The timings in this guide are general, and your product's pack is the authority.
What Temperature Should Your Fridge Be?
The US Food and Drug Administration recommends keeping your fridge at or below 4°C and your freezer at minus 18°C (FDA). Bacteria multiply much faster above that.
A few habits make a real difference:
- Store dairy on a shelf, not in the door. The door is the warmest part of the fridge and warms up every time it opens.
- Don't overfill the fridge. Cold air needs to circulate.
- Use a fridge thermometer if you're not sure your fridge is cold enough. Many dials aren't marked in degrees.
How Should You Store Pouch Milk?
Refrigerate it immediately. If milk is delivered early in the morning, put it in the fridge as soon as you bring it in. The FDA's guidance is not to leave foods that need refrigeration at room temperature for more than two hours, or one hour when it's above 32°C.
Use it by the date on the pack. Pasteurised milk is heat-treated to make it safe, but it still needs to stay cold, and its shelf life depends on how it's been kept. Our milk is pasteurised and homogenised and packed in sealed pouches: follow the use-by date printed on the pouch.
Keep pouches sealed until you need them. An unopened, chilled pouch keeps better than an opened one.
How Do You Store Milk After Opening It?
- Transfer it to a clean, covered container or clip the pouch shut. Open milk absorbs fridge smells and spoils faster.
- Pour out what you need and put the rest back straight away. Don't leave the jug on the counter through breakfast.
- Never pour used milk back into the container of fresh milk.
- Use opened milk within a day or two, and always within the pack's date. Opened milk keeps for less time than sealed milk.
Should You Boil Milk Before Storing It?
Many Indian households boil milk as soon as it arrives. With pasteurised pouch milk, boiling isn't needed to make it safe, because pasteurisation has already done that. Some people still prefer to boil it for taste, or to make malai.
If you do boil it:
- Cool it quickly and refrigerate it in a covered container. Don't leave boiled milk out for hours to cool.
- Boiling doesn't extend the use-by date of milk that's already close to it, and it won't rescue milk that has started to turn.

How Long Does Paneer Last, and How Should You Store It?
Packaged paneer: keep it sealed in the fridge and use it by the date on the pack. Once opened, use it within a couple of days.
Keep it soft: paneer dries out and hardens in the fridge. Two ways to prevent that:
- In water: put it in a container, cover it with clean drinking water, close the lid, and change the water every day.
- Airtight: wrap it closely or keep it in an airtight box so it doesn't dry out or absorb smells.
Revive hard paneer: soak cubes in warm water for 10 to 15 minutes before cooking. It softens noticeably.
Buy real paneer: storage can't fix paneer that wasn't real to begin with. See our guide on how to check if paneer is real.
Can You Freeze Paneer?
Yes. Freezing keeps paneer much longer, but it changes the texture: thawed paneer tends to be more crumbly and less soft.
To freeze it well:
1. Cut it into cubes.
2. Spread them on a plate so they freeze separately, then move them to an airtight bag or box.
3. Freeze at minus 18°C.
To use it: thaw it in the fridge, then soak the cubes in warm water for a few minutes to soften them. Frozen paneer works best in gravies and bhurji, where a slightly crumbly texture doesn't matter.
How Long Does Dahi Keep in the Fridge?
Store-bought dahi: keep it covered in the fridge and use it by the date on the pack.
Homemade dahi: refrigerate it as soon as it sets, keep it covered, and use it within a few days. It gets steadily sourer as it ages.
A few habits help:
- Use a clean, dry spoon every time. A used spoon introduces other bacteria.
- Keep it covered so it doesn't absorb fridge smells.
- Whey on top is normal. Stir it back in or pour it off.
Sourer dahi isn't necessarily spoiled: it's good for kadhi or marinades. But see the spoilage signs below. (For making your own, see how to set thick dahi at home.)
How Can You Tell if Milk, Paneer or Dahi Has Gone Off?
Milk: a sour or unpleasant smell, a sour taste, lumps, or curdling when you heat it. If milk splits as it warms, it has turned.
Paneer: a sour or off smell, a slimy surface, yellowing, or any mould.
Dahi: mould of any colour, a pink or orange tinge, a yeasty or fizzy smell or taste, or a bitter flavour. Sourness alone isn't a sign of spoilage, but these are.
When in doubt, throw it out. Smelling and tasting help, but they won't detect every harmful bacterium.
What Should You Do in a Power Cut?
Power cuts are common in some areas, especially in the monsoon. The FDA's guidance:
- Keep the fridge door closed. An unopened fridge keeps food cold for about four hours.
- Throw out perishable food, including milk, that has been above 4°C for four hours or more.
Practical steps for longer cuts:
- Use the dairy first and plan meals around what's in the fridge.
- Move milk and paneer to the freezer compartment, which stays cold longer.
- Buy smaller quantities more often during the monsoon if cuts are frequent. Daily delivery helps here: fresh milk arrives each morning instead of sitting in the fridge for days.
Why Does Fresh Delivery Make Storage Easier?
The simplest way to keep dairy fresh is not to store it for long. With a daily subscription, fresh milk arrives between 5 and 8 AM every morning in Pune and Mumbai, so you're rarely keeping milk for more than a day.
Everything we sell, from milk to paneer and dahi, comes from our own farm's milk. Doodh & Co is single-origin: we never buy in milk from other farms or mix it. Our milk is pasteurised, homogenised and packed in sealed pouches, and we're an FSSAI-licensed dairy manufacturer (Lic. No. 11526088000179).
Conclusion
Storing dairy well comes down to a few rules: keep your fridge at 4°C or colder, refrigerate milk as soon as it arrives, don't leave dairy out for more than two hours, keep paneer and dahi covered, and follow the date on the pack. Paneer freezes, with some change in texture, and when anything smells or looks off, throw it out.
