Bordeaux grapes white

In Bordeaux dry white wines are made, particularly in Entre Deux Mers.
And there the famous dark-yellow sweet wines are made, from by botritus (pourriture noble) affected, dried grapes, particularly in Sauternes.

Sauternes is a bulky, full-sweet wine with high acidity. The acidity provides the balance in flavour. The most expensive Sauternes is the Chateaux d’Yquem, of which half a bottle usually costs over €100,-.

The three grapes for white Bordeaux are:
Sauvignon blanc
Muscadelle
