Sauvignon became the main grape variety in the twentieth century. It has a different expression on our terroirs to anywhere else and thus enabled Sancerre to receive the Appellation d'Origine Contrôlée classification in 1936. The reds and rosés received the classification in 1956. The white Sancerre wines, made exclusively from Sauvignon Blanc grapes, now account for 80% of production. Pinot noir grapes are reserved for the production of red and rosé Sancerre wines. By taking advantage of the advances in transportation methods, Sancerre wines quickly became very popular in Parisian bars and bistros. They were then exported worldwide. Today, 70% of our produce is exported across the world.
