Its parentage has not been established by DNA analysis; Robinson, Harding & Vouillamoz (*Wine Grapes*, 2012, ISBN 978-1-846-14446-2) report the parents as unknown. Widely planted historically in South America (Argentina, Chile) and Australia; at its peak it was among the most planted white grapes in the world by surface area, but acreage has contracted significantly as Chardonnay and Sauvignon Blanc expanded globally. Current global plantings are approximately 18,000 hectares (approximate; verify against current OIV data). Registered in the OIV VIVC (Wikidata: Q275). #### Viticultural Characteristics Thin skins and moderate-to-high yields make Semillon highly susceptible to *Botrytis cinerea*. In Sauternes and Barsac, morning mist from the Ciron river creates humidity, and afternoon sun dries the clusters, enabling noble rot rather than grey rot, concentrating sugars and acids for botrytized sweet wines. In dry years the same sites produce dry whites. Hunter Valley, Australia operates in cooler and more humid conditions; early harvesting at relatively low sugar levels preserves high natural acidity. #### Winemaking Style Three principal expressions: dry blend (Pessac-Leognan, Bordeaux: barrel-aged blend with Sauvignon Blanc for structure and longevity); dry varietal (Hunter Valley: unoaked, stainless steel, requiring 5 to 20 years bottle age for the classic toast, beeswax, and lanolin profile to emerge from what appears thin and austere when young); botrytized sweet (Sauternes and Barsac: noble-rot concentration produces wines of extraordinary richness and 20-plus-year longevity, Chateau d'Yquem the global benchmark). #### Food Pairing - Young dry Hunter Valley: plain grilled white fish, oysters on the shell - Aged Hunter Valley (10-plus years): lobster, rich seafood bisque, roast chicken - Pessac-Leognan dry blend: sole meuniere, sea bass, white asparagus - Sauternes: foie gras (the canonical match), Roquefort, creme brulee, fresh peaches #### Sources *Claims marked (✓) were cross-referenced against publicly accessible documents at time of authorship (2026-09-02)* - (✓) Robinson, J., Harding, J., & Vouillamoz, J.

Semillon is a white grape from Bordeaux that produces three principal styles: dry blended whites (Pessac-Leognan), dry varietal whites (Hunter Valley, Australia) that require years of bottle age, and botrytized sweet wines (Sauternes, Barsac) that are among the world's most age-worthy. ### What makes Sauternes wine so sweet? Sauternes is made primarily from Semillon affected by noble rot (Botrytis cinerea). In optimal autumn conditions, morning mist from the Ciron river creates humidity for fungal growth, and afternoon sun dries the berries. Noble rot concentrates sugars, acids, and flavor compounds to extraordinary levels. ### Why does Hunter Valley Semillon taste so different when aged? Young Hunter Valley Semillon is lean, high-acid, and austere. With 5 to 15-plus years of bottle age, it develops toast, beeswax, lanolin, and dried citrus peel complexity through non-oxidative bottle aging processes. This transformation is a uniquely regional style not replicated elsewhere. ### What food pairs with Semillon? Young Hunter Valley Semillon pairs with oysters and grilled white fish. Aged Hunter Semillon suits lobster and rich seafood. Pessac-Leognan dry blend suits sole meuniere and sea bass. Sauternes is the canonical pairing for foie gras and matches Roquefort and creme brulee.
