Sauternes - Barsac
At the opposite of what you might think, Sauternes and Barsac are not "easy" wines to taste. Whether young or very old, Sauternes have such a great aromatic depth that it is almost impossible to fathom it, even for great tasters.
There is a classification established in Sauternes since 1855 (as much to say yesterday). To put it simply, Yquem is above the rest in front of Rieussec, Coutet, Guiraud, La Tour Blanche and many others. Each of these Château has its own style, more or less powerful, more or less spicy etc. Also it is important to select a Sauternes according to what you like, without taking into account the classification.
For the Sweet wines and perhaps even more than elsewhere, the quality of the vintage is capital, because it is the climatic conditions that determine the presence, or not, of the famous Botrytis or noble rot.
