Is it necessary to add yeast to grape juice in order to make wine?
The vast majority of grape juice will not spontaneously ferment on its own. This is because the naturally occurring yeast on the grape skin is not usually sufficient in quantity to start fermentation. This is why adding yeast is generally considered necessary in order to make wine.
There are a few exceptions to this rule. If you are using very ripe grapes or if you are using wild yeast, it is possible that grape juice will ferment on its own. However, these are relatively rare circumstances. In most cases, adding yeast is the best way to ensure that grape juice will ferment and turn into wine.
