Once you open the bottle, the juice should stay fresh for 10 days and even 3 weeks. As always, it depends as much on the quality of the juice as it is on how you store it. Juices that aren't made from fresh fruit usually have a lot of added sugar, which acts as a preservative. While fresh apple cider will only stay good for about a week after the expiration date, bottled apple juice can be kept in good condition for up to three months.
Juice that has been spoiled will usually have a sour smell or mold will grow. Opened orange juice lasts up to a week in the fridge. However, we recommend that you consume it right away. Since it's already open, it can easily be damaged, as it can be prone to mold and bacteria.
Frozen and thawed apple juice may not be the tastiest drink on its own, but adding a few cubes of frozen juice to a glass of water on a hot day can work wonders. So how long does the juice last? When properly stored, the shelf life of fruit juice after its expiration date is approximately. When microorganisms in the air enter the juice container, they begin to ferment the fruit, which changes the taste and aroma of the juice. Similar guidelines apply to other juices, such as orange juice (here's how long orange juice lasts), etc.
Juices that are all fruit juices spoil sooner than juices with added sugar and preservatives, since the natural sugars in the fruit will begin to ferment over time.
