Grape wine is an alcoholic beverage made from fermented grapes. The fermentation process involves converting the sugars in the grapes into alcohol and carbon dioxide, primarily through the action of yeast. Different grape varieties, such as Cabernet Sauvignon or Chardonnay, contribute unique flavors and characteristics to the wine. There are various types of grape wine, including red, white, and rosé, each produced using different methods. Red wine is made with the grape skins, while white wine is typically produced without them. Wine regions around the world, like Bordeaux in France or Napa Valley in the United States, are known for their distinct grape wines.
