Wine is fermented grape juice. Add yeast to grape juice and the yeast ferments the natural sugar into alcohol and carbon dioxide.
The word ferments is a verb. It can also be a plural noun.
The leather containers used at the time to hold wine. They could not be reused as the gas pressure from fermentation the second time would burst them. The point isn't the wine skins actually. It's old wine and new wine. New wine still has to ferment. Old wine doesn't. So, if you fully fill up a skin that has had fermented old wine in it with new un-fermented wine as the new wine ferments and produces gasses, it will burst the skin as it stretches.
