White wine grapes are a variety of grapes specifically cultivated for producing white wine. These grapes are typically green or yellow in color and have a higher acidity compared to red wine grapes. Common types include Chardonnay, Sauvignon Blanc, and Riesling, each contributing unique flavors and aromas to the wine. The process of making white wine involves pressing the grapes to extract their juice, which is then fermented without the grape skins. This method helps maintain the light color and crisp taste associated with white wines. The choice of grape variety significantly influences the final product's character and quality.
