Sémillon is a golden-skinned grape used to make dry and sweet white wines, mostly in France and Australia.

The Sémillon grape is native to the Bordeaux region,France. Sémillon wines are rather heavy, with low acidity and an almost oily texture. It has a high yield and wines based on it can age a long time. Along with Sauvignon blanc and Muscadelle,

Sémillon is one of only three approved white wine varieties in the Bordeaux region. It was once considered to be the most planted grape in the world, although this is no longer the case. In the 1950s, Chile's vineyards were made up of over 75% Sémillon.

The grape is also key to the production of sweet wines such as Sauternes. For the grapes to be used for sweet wine production, they need to have been affected by Botrytis (also known as "noble rot"). This fungus dries out the grapes, thus concentrating the sugar and flavours in the grape berry.
