Grape juice can stay fresh or not so fresh for a while. Here’s why:

When you get grape juice from the store, it’s usually in a tight container, like a glass bottle or plastic jug. This helps keep it fresh. If you don’t open it, it can be good for up to 8 to 12 months

But it depends on how it’s stored, like the temperature and the container it’s in.

Keep grape juice in a cool, dry place, not too hot or cold. A fridge is best because it stays fresh longer there.

Once you open grape juice, it doesn’t last as long. Air, light, and changes in temperature make it go bad faster. To keep it fresh, put it in the fridge and drink it in a week or so. Some grape juices have lids you can close to help them stay fresh.

Some grape juices have stuff in them to make them last longer, like citric acid or vitamin C. But still, follow the storage rules to keep it yummy and safe.

How to Store Grape Juice

Keeping grape juice fresh is super important. No matter if you made it or bought it, you must do a few things to keep it yummy and healthy.

First, keep everything clean. Wash your stuff and your hands. This stops bad stuff from growing in the juice.

Use good containers. Glass or safe plastic bottles with tight lids are best. They won’t change the juice’s taste. Make sure they are clean and dry.

Leave some space in the container for freezing or if it’s in the fridge. Close it tight to keep the juice fresh.

How you keep the juice depends on how long you want it to last:

Short Time (Fridge)

If you’ll drink it soon, keep it in the fridge at 32°F to 40°F. Don’t put it near smelly food.

Long Time (Freezer)

For a long time, freeze it. Leave space in the container and write the date. Put it in the freezer at less than 0°F. When you want it, thaw it in the fridge or at room temp. Use it in a few days and don’t freeze it again.

Canning (Preserving)

If you can, can it! This can make it last a year or more. Follow the rules to seal it right.

Lastly, check it sometimes. If it smells bad, changes color, or gets moldy, throw it away.


To wrap it up, grape juice can go bad. How long it lasts depends on where you put it, how it’s packed, and if you’ve opened it. If it’s unopened and stays in a cool, dark place, it can be good for months to a year. 

But once you crack it open, pop it in the fridge, and finish it within a week. Look, sniff, and taste it to make sure it’s still good. If it smells funny or has weird stuff growing in it, throw it away to stay safe. Just remember to store your grape juice right to enjoy it at its best!
