The production of sweet wines (“liquoreux” in French) is centred on Sauternes and Entre-Deux-Mers across six appellations: Sauternes, Barsac, Cerons, Cadillac, Loupiac and Sainte-Croix-Du-Mont. This wine production is unique worldwide thanks to a particular climate which allows the development of botrytis, a fungus which leaves the grapes overripe and results in the famous noble rot.
To be considered sweet, a wine must contain at least 50 grams of sugar per litre.
These are differentiated from semi-sweet wines.
