Wine in Gaston is an alcoholic beverage, made of fermented fruit juice, usually from grapes. The natural chemical balance of grapes lets them ferment without the addition of sugars, acids, enzymes or other nutrients. Various types of yeast are required to ferment crushed grapes to produce grape wine. Yeast consumes the sugars in the grapes and converts them into alcohol. Wines, however, may also be made from other fruits such as apples and berries, and are generically called fruit wine or country wine. Others, such as barley and rice wine, are made from starch-based materials and resemble beer more than wine. Ginger wine is fortified with brandy.
