Semillon is the understated elegance of white wine, and Australia has a claim on it that no other country can match. In the Hunter Valley, growers pick it early, bottle it at a whisper of 10 or 11% alcohol, and produce a wine that tastes of lemon and not much else when young, then transforms over a decade into toast, honey and lanolin without ever seeing a barrel. Nobody else on Earth does this. It is our great white wine secret.
Elsewhere it plays a different role. In Bordeaux it is the backbone of Sauternes, the world’s most famous sweet wine, and in Margaret River it is Sauvignon Blanc’s best friend in the blends Western Australia does so well.

What Does Semillon Taste Like?
Young Hunter Semillon: lemon, lime, green apple, a chalky freshness and a light, almost skinny frame. Aged Hunter Semillon: buttered toast, honey, beeswax and dried straw, still with that lemony spine. Barrel-fermented versions from Margaret River add richness and nut; Sauternes adds apricot, marmalade and glorious sweetness.
| Aspect | Rating out of 5 | Characteristic |
|---|---|---|
| Sweetness | 🍷 | Dry in Australia, though in Sauternes it becomes gloriously sweet, as unpredictable as British weather |
| Body | 🍷🍷🍷 | Medium-bodied, lean and racy in the Hunter, richer with oak, a lord who can also do casual |
| Tannins | – | As noticeable as a quiet guest at a dinner party |
| Acidity | 🍷🍷🍷🍷 | Medium to high, the reason Hunter Semillon lives for decades |
| Alcohol by Volume | 🍷🍷🍷 | Generally 11–13.5%, and as low as 10% in the Hunter, as comforting as a cuppa |
Each wine glass icon is one point on a 5-point scale: one glass is low, five is high, based on the grape’s typical style.
Where It Grows
Bordeaux grows the most, for both dry white blends and the sweet wines of Sauternes and Barsac, where a friendly fungus called noble rot shrivels the grapes into honeyed concentration. Washington State and South Africa make good versions too.
But Australia is where Semillon became a legend. The Hunter Valley’s unoaked, low-alcohol, age-for-twenty-years style is unique in the world, and Tyrrell’s Vat 1 is one of the most decorated white wines in the country. Margaret River takes a different path, blending it with Sauvignon Blanc (the famous SSB) or fermenting it in oak for richer wines. The Barossa and Clare grow it too, often in a rounder, fuller style.
How to Serve It
Temperature: 8–10°C for young dry styles, a little warmer (10–12°C) for aged Hunter Semillon so the toasty complexity shows.
Glass: a medium white wine bowl; see the glasses roundup.
Decanting: not needed.
Ageing: the Hunter’s party trick. Buy young, wait five to fifteen years, and watch lemon water turn into liquid toast. Blends and oaked styles are best within a few years.
What to Eat With It
Young Semillon and seafood are inseparable: oysters, prawns, fish and chips, and it is a superb match for cod and other white fish. Aged Hunter Semillon loves roast chicken and creamy pasta. Sauternes with blue cheese or crème brûlée is one of the great pairings. More in the pairing guides.

Frequently Asked Questions
Why is Hunter Valley Semillon so special?
Because nowhere else makes it this way. Picked early, unoaked and bottled at around 10 to 11% alcohol, it is almost austere when young, then ages for decades into toasty, honeyed complexity. It is one of Australia’s genuine contributions to the wine world.
What is SSB?
Semillon Sauvignon Blanc, the white blend Margaret River made famous (SBS if Sauvignon leads). Semillon adds weight and texture, Sauvignon adds aromatics and zip. It is the ideal Australian seafood white.
Is Semillon sweet?
In Australia, almost always dry. In Bordeaux’s Sauternes and Barsac it becomes one of the world’s great sweet wines, thanks to noble rot concentrating the sugars. Same grape, opposite ends of the sweetness scale.
How long can Semillon age?
Hunter Semillon comfortably ages ten to twenty years, and the best go longer. Sauternes can last half a century. Blends and everyday bottles are best within two or three years.
What is Semillon similar to?
Young Hunter Semillon is closest to a dry Riesling in its lemony purity; aged versions resemble mature white Burgundy. Chenin Blanc is a spiritual cousin in texture and ageing ability.
