What is this? Fruits fermenting in the fridge on their own is quite rare but can happen. This could spark a fermentation process since yeast from the grapes and yeast in the air outside the fridge may have latched onto the sugar of the mashed grapes and start fermenting.
Can Fruit Juice ferment on its own?
Any fruit can ferment on its own, with the right conditions. For a natural fermentation to start there has to be a presence of yeast and bacteria. The fermentation usually happens when the fruit is smashed and the yeast is allowed to react to the sugar content in the fruit juice, which can ferment into alcohol.
