Sémillon is a white grape variety originating from the Bordeaux region of France. It is known for its versatility, producing a range of wine styles from dry to sweet. Sémillon grapes are typically characterized by their thin skins and high sugar content, making them ideal for late harvest wines, such as Sauternes, which are renowned for their rich flavors. The grape is often blended with Sauvignon Blanc to create balanced white wines, particularly in Bordeaux and Australia. In regions like Hunter Valley, Sémillon is celebrated for its ability to age well, developing complex flavors of honey and nuts over time.
