Wine
Wine is an alcoholic drink made from fermented fruit. Yeast consumes the sugar in the fruits and converts it to ethanol and carbon dioxide, releasing heat in the process. Though wine can be made from a variety of fruit crops such as plum, cherry, pomegranate, blueberry, currant and elderberry, it is most often made from grapes, and the term "wine" generally refers to grape wine when used without a qualifier. Different varieties of grapes and strains of yeasts are major factors in different styles of wine. These differences result from the complex interactions between the biochemical development of the grape, the reactions involved in fermentation, the grape's growing environment (terroir), and the wine production process.
