A wine grape is a type of grape specifically cultivated for winemaking. These grapes are typically smaller and have thicker skins compared to table grapes, which are meant for eating. Wine grapes contain higher sugar levels and more complex flavors, making them ideal for fermentation. Common varieties include Cabernet Sauvignon, Chardonnay, and Merlot. The process of turning wine grapes into wine involves harvesting, crushing, and fermenting the fruit. During fermentation, yeast converts the sugars in the grapes into alcohol, resulting in the diverse range of wines enjoyed worldwide. Factors like climate, soil, and grape variety significantly influence the final taste of the wine.
