This is my hands-down favorite Sancerre.  I say it again and again a Silex Sancerre is well worth the few extra $$ you pay over a village-level Sancerre. 

Tasting Notes :

Pale gold in colour, the Silex Blanc is an elegant embodiment of sauvignon blanc characteristic of the Sancerre region, with a nose of little white flowers. In the mouth it is silky, round and delicate, with a pleasing richness and complexity on the back palate. It has a good balance between alcohol and acidity levels in the mouth, marked with mellow notes of wood (acacia, well-ripened exotic fruits, with minerals in the background). Balance and refinement are the underpinnings of the Cuvée Silex.

Food Paring: The Cuvée Silex is better suited to refined dishes, such as:

• Firm-textured saltwater fish with traditional French sauces
  
• Coquilles Saint-Jacques
  
• Lightly seared foie gras
  
• Poultry or veal escalope in cream sauce
  
• With various cheeses.
