Wine is an alcoholic drink typically made from fermented gapes. Yeast consumes the sugar in the gapes and converts it to ethanol, carbon dioxide, and heat. Different varieties of gapes and strains of yeasts produce different styles of wine. These variations result from the complex interactions between the biochemical development of the gape, the reactions involved in fermentation, the gape's growing environment (terroir), and the production process. Many countries enact legal appellations intended to define styles and qualities of wine. These typically restrict the geographical origin and permitted varieties of gapes, as well as other aspects of wine production. Wines not made from gapes involve fermentation of additional crops including, rice wine and other fruit wines such as plum, cherry, pomegranate, currant and elderberry.
