If you have white grapes, you'll be straining the skins and pulp off and only using the juice. Otherwise the process is the same for both. Orange, apple, and grape juice, for example, are all high in ethanol (up to 0.77 g/L), making them feel drunk. Fermenting grape must, in addition to being cloudy, fizzy, sugary, sweet, and unstable, has an alcohol content that can range from 2 to 10%, though it is most commonly consumed with a beer – say, 4 or 5%.

Despite the fact that there are over 1,500 yeast species, we are primarily concerned with one type, S.C. Yeast. Other yeasts can be used to turn grape juice into wine, but they often taste off or spoiled. If the yeast have consumed all of the sugar in the must, or if the alcohol level has reached too high, the yeast will stop fermentation. You can use yeast from a variety of sources to begin fermenting your grape juice before adding your own yeast. If you want to ferment your grapes, you must first determine the sugar content.
