### Summary

Sémillon is a golden-skinned Bordeaux grape central to dry Graves whites and sweet Sauternes, and to long-lived Hunter Valley wines in Australia. Thin skins make it especially receptive to noble rot in humid autumns.

### Description

Sémillon (often written Semillon in New World labeling) brings body, lemon-curd fruit, and a waxy texture that ages toward toast and honey. In Bordeaux it partners with [[sauvignon-blanc]] for dry blends and dominates many Sauternes cuvées when Botrytis cinerea concentrates sugars.

Hunter Valley’s humid subtropical edge yields distinctive low-alcohol, long-lived dry Semillon bottled early and aged in bottle rather than oak. Bordeaux’s Left Bank sweet-wine communes depend on autumn mist for noble rot cycles that Sémillon’s thin skins invite.

Production for dry styles emphasizes early harvest and protective handling; sweet styles require successive tries through the vineyard as rot develops unevenly. Global plantings shrank with Bordeaux white acreage losses, yet icon estates still treat Sémillon as structural insurance beside more aromatic partners.

## Frequently asked questions

### What is Sémillon used for?

Dry white blends, bottle-aged Hunter Valley Semillon, and botrytized sweet wines such as Sauternes.

### How do you pronounce Sémillon?

Roughly “seh-mee-yon” in French; English labels often drop the accent and say “SEM-ih-lon.”

### Why is Sémillon good for dessert wine?

Thin skins and susceptibility to noble rot allow sugar concentration while retaining enough acidity for balance.
