Wikipedia Article About Sémillon on Wikipedia Sémillon is a golden-skinned grape used to make dry and sweet white wines, most notably in France and Australia. In France, the Sémillon grape is grown mostly in Bordeaux. There, it is blended with Sauvignon blanc and Muscadelle. When dry, it is referred to as Bordeaux blanc and is permitted to be made in the appellations of Pessac-Léognan, Entre-deux-mers and other less renown regions. In this form, Sémillon is generally a minor constituent in the blend.
