If it's been opened before, Yes. I left one in my bedroom for a week by accident. The container became pressuized and it smelled terrible...
this is a guess.. orange juice
Unrefrigerated grape juice can typically remain safe to drink for about 2 to 3 hours at room temperature. However, if the juice has been opened, it should ideally be consumed within a day to prevent spoilage or fermentation. If stored unopened in a cool, dark place, it may last longer, but refrigeration is recommended to maintain quality and safety. Always check for signs of spoilage before consuming.
Apple juice has more sugar.
Yes, grape juice can ferment in the fridge if it contains natural sugars and yeast, which can lead to the production of alcohol.
Prune juice on its own has flushing effects on the digestive system. Opened, unrefrigerated prune juice is seen as potentially dangerous to drink depending on how long it has been left out, or how old the juice is.
If the juice is within a sealed container, it may last a couple of days before beginning to spoil. If left in an open container, it can begin to ferment within hours, especially in warm weather. Storage in refrigeration or a dark closed space will help to last beyond a week.
2-3 weeks for hair products. 2-3 years for consumption

Yes, grape juice can ferment on its own due to the natural presence of yeast in the environment. Fermentation occurs when yeast consumes the sugars in the grape juice and produces alcohol as a byproduct.
Some examples of Fermentation would be in the manufacture of wine and beer. More simply, if you leave apple juice open and unrefrigerated for a period of time, bubbles will begin to form as it begins to ferment. At first, some alcohol will form, but eventually it will end up as vinegar.
you have to ferment it, and add certain ingredients
Wine. Grape juice will eventually turn to wine if allowed to ferment.
