Sémillon is one of the wine world’s unsung heroes. The gold-skinned grape produces France’s most famous and revered sweet wines, notably Sauternes, and some of the greatest dry white wines of Australia.  And yet, few Sémillons between these two extremes attract much attention. The thick-skinned grape is characterized by its autumnal colors in the vineyard. Sémillon is vigorous and easy to cultivate, and buds later (but ripens earlier) than its most common blending partner, Sauvignon Blanc. Although the fruit is usually bright golden-green, it is not uncommon to find pink- and copper-colored berries around harvest time. Certainly, when the grapes are affected by the noble rot, Botrytis cinerea, they take on darker hues and gnarled textures; viticulturists view the sight with anticipation and excitement.
