Chablis, a village and region in northern Burgundy, is all about Chardonnay, making arguably the best unoaked versions in the world. The wines here are defined by a crisp acidity and a strong mineral backbone. The area's unique Kimmeridgian limestone soil, packed with marine fossils, gives the wines a distinctive flinty edge. One slope overlooking the village holds the seven Grand Cru vineyards, while Premier Cru sites are scattered along both sides of the Sereine River, which cuts the region in half. Chablis is the ultimate destination for highly mineral white wines.
