naturally fermented wine is made from grape juice from squeezed grapes. There is a substance in the skin of the grapes that causes the fermentation. using it with flour would create fermentation in the mix which will be used to have the bread rise. Raisins would have more concentrated sugar which is food for the natural yeast. It might go bad sometimes because you might have some other wild strain of bacteria that if used in winemaking would make pretty horrible wine. Occasional bad batches are a hazard of natural winemaking also. Supposedly, the ancient Egyptians discovered beer as a probably accidental byproduct of breadmaking. As for the raisins, perhaps water was added? Perhaps they were late harvest grapes which are sweeter, perhaps only partially dried to concentrate the grape sugar.
