One of the most baffling subjects that confronts the budding wine enthusiast is the deciphering of the myriad of information contained on the bottle label, especially that contained on wine bottles from European countries. Once the basic rules are taken on board it becomes a lot simpler. Whereas most New World countries put details of the grape varieties on the front label, a lot of European regions do not, and as this is the most basic of information for taste purposes why is this the case?
European winemakers tend to put more emphasis on the place of origin. For instance, a Bordeaux red typically wont say Cabernet or Merlot on the front label, but instead have the name of the chateau where it was made, and usually the part of Bordeaux where it was made, for example Haut-Medoc. Similarly a Sancerre is totally Sauvignon Blanc, but an in depth analysis of the label will leave you none the wiser. For the French the important factor is that the wine comes from Sancerre in the Loire valley and for them it is inbred knowledge that white Sancerre is Sauvignon Blanc.
Moving south to Spain, red Rioja declares itself as Rioja on the label, not Tempranillo the grape...
