Depending on where it is grown and the winemaking philosophy, Sémillion may have flavours and aromas, which include citrus fruits, flowers, ripe fruits, minerals and lanolin.
Sémillon is a white grape mostly grown in France and Australia, it has a thin skin and it is susceptible to botrytis and for that reason, it is used to make sweet wine, particularly, Sauternes AOC and Barsac AOC.
