What is the ruling on preserving grape and fruit juice for a long period, whether by refrigeration or storage?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: The means of preserving juices, including grape and fruit juice, for a long period, whether by refrigeration or storage, and it may exceed three days, so what is the ruling on that?

Answer:
These matters have changed the situation now. If they are preserved in cans and things are added to them that prevent their fermentation, there is no harm in their remaining, even if the period is long, because substances that preserve them from fermentation and spoilage have been added to them.
So there is nothing wrong with that. And nowadays, juices that are drunk often have a duration, and they have a year or a month, or it is written on them when their use expires, the duration of use is written. These are preserved from fermentation by these preservatives that are added to them. But this is for three days, or if the day was not intense, there was nothing in it, there were no means of manufacturing and education regarding the current situation.
