The process of making wine is called fermentation. This involves the conversion of sugars present in grapes into alcohol and carbon dioxide, primarily facilitated by yeast. The fermentation process typically begins once the grapes are crushed, allowing the yeast to access the sugars. Depending on the type of wine being made—red, white, or sparkling—the fermentation conditions (like temperature and time) will vary. After fermentation, the wine is usually aged in barrels or tanks before being filtered and bottled. This intricate process not only produces alcoholic beverages but also contributes to the distinctive flavors and characteristics associated with different wines.
