Sancerre AOC

Overview

Sancerre stands as the world’s benchmark for Sauvignon Blanc, producing wines of crystalline purity, mineral precision, and remarkable terroir expression from the chalky hills above the Loire River. The appellation’s diversity of soils—flint (silex), limestone (caillottes), and clay-limestone (terres blanches)—creates distinct wine styles that make Sancerre endlessly fascinating for students of terroir. While white Sauvignon Blanc dominates production and reputation, Pinot Noir has been grown here for centuries and is increasingly respected. For enologists, Sancerre offers essential study in Sauvignon Blanc at its finest, soil-driven wine expression, and the art of crafting wines where terroir speaks clearly.
