Notice the phrase ‘intervention’ in the naturally occurring fermentation process is kept to a minimum. There's no wine without fermentation, which occurs when sugar converts to alcohol and carbon dioxide through the aid of microorganisms. Yeasts.Many winemakers (and brewers and other artisans) will inoculate their product with a chosen strain of cultured yeast that offers particularly desirable and consistent qualities. This is a highly common process and many of the wines in the world have some sort of inoculation, as deemed appropriate by the winemaker.But, strictly speaking, inoculation isn't entirely necessary. In fact, if fruit were left to its own devices — say, grapes that have fallen to the ground — it can often partner up with wild yeast (and bacteria, which provide acids that yeasts love) and be transformed. There are even stories of wild animals eating naturally fermented fruit and showing signs of intoxication.Wild yeasts (also called native, indigenous, natural or ambient) hitch into the cellar on the grapes, or cling to cellar and vineyard equipment and follow their hunger to the vats. Wild yeast is responsible for spontaneous fermentation because it is present in the grape juice or must and while it's there, it does its thing.
