"White varietals" refer to types of grapes used to produce white wine. Common examples include Chardonnay, Sauvignon Blanc, and Riesling. These grapes are typically green or yellow in color and are known for their ability to create a wide range of flavors, from crisp and fruity to rich and creamy. The production of white wine generally involves pressing the grapes to extract their juice, which is then fermented without the skins. This process helps to maintain the light color and fresh taste associated with white varietals. Each varietal has unique characteristics influenced by factors like climate, soil, and winemaking techniques.
