Semillon is a white grape variety that is widely grown in many wine regions around the world, including France, Australia, South Africa, and Argentina. It is often blended with other varieties, most notably Sauvignon Blanc, to create white wines with excellent aging potential and complex flavors. Semillon wines are typically medium to full-bodied with moderate acidity and flavors of lemon, honey, and sometimes oak. The grape is also used to make sweet wines, such as Sauternes from Bordeaux, which are known for their luscious, honeyed flavors and aromas. Overall, Semillon is a versatile grape that produces a range of styles of white wines.
