The sweet whites of Bordeaux owe their existence to one of Natures bizarre gifts. The climate of the area promotes the development of a particular form of mould – Botrytis cinerea, more commonly known as “noble rot”. This effects the grapes, especially the Semillon, and has the effect of splitting the skins of the grape which allows evaporation of a portion of the water content thereby increasing the sugar concentration of the juice. The resulting wines are rich, sweet and wonderfully textured. Whilst noble rot is not unique to Bordeaux, it is here that the very finest of these styles of wine are found, in the communes of Sauternes and Barsac.
