Sauternes and Barsac 1999
A very fine vintage of classic quality
There was rain during the second half of September, and October was fine. The Sauvignon Blanc matured very rapidly, and could be picked in early September. The vintage was swift, as sugar levels were high and botrytis was widespread. There was little variation in quality between early and late pickings. Quality is homogeneous, and seems slightly better than 1998.
