every single label ....

“Clos du Curé” is made solely with Pinot Noir grapes.
  “Les Echelles de Lisson” is a blend of grapes. Cabernet Sauvignon and Cabernet Franc, vinified together, account for the major part, with Merlot, Côt and Petit Verdot in lesser proportions which vary depending on the vintage.  
  a glass of Mourvèdre   “Clos de Cèdres” is 100% Mourvèdre.  

All our wines are vinified for drinking when aged. It is quite normal to find some deposits in the bottle.
