Sémillon grape bunch

🍇 Sémillon

Pronunciation: seh-MEE-yohn /se.mi.jɔ̃/
White Origin: Bordeaux, France

About Sémillon

Sémillon is a golden-skinned grape that produces rich, waxy wines with low acidity. While rarely vinified alone outside Australia, it's an essential component in Bordeaux's white wines and the primary grape in Sauternes, the world's most famous sweet wine.

The grape's thin skin makes it highly susceptible to botrytis (noble rot), which concentrates sugars and adds complex honey and marmalade flavors. In Sauternes and Barsac, botrytized Sémillon creates some of the world's most luscious and long-lived dessert wines.

Australia's Hunter Valley produces unique, age-worthy dry Sémillon – picked early, unoaked, and apparently simple when young, these wines transform with age into complex, toasty masterpieces. It's one of the wine world's hidden gems.

Vidal

Why confused: Both can make sweet wines with apricot/honey character

How to distinguish: Vidal: Sémillon (Sauternes) has more botrytis complexity; Vidal icewine is cleaner, more direct fruit
Compare side by side →

Blind Tasting Tips

Colour: Deep gold, especially with age or botrytis.

Key markers: Waxy, lanolin texture is distinctive. Lemon and fig fruit. Low acidity. Toast and honey develop with age. Marmalade indicates botrytis.

Structure: Full body with LOW acidity. Rich and weighty. Can feel oily or waxy in texture.
