White blends can include any number of different varietals and often refers to any white wine that contains more than one white grape varietal in the final product, though certain white blends can have their own designations as recognized wines despite comprising multiple grapes. However there are common complements especially in French and Italian wine making. The classic white bordeaux blend is a mixture of Semillon and Sauvignon Blanc, and occasionally includes Muscadelle and Sauvignon Gris.
