Chablis is a renowned white wine region in northern Burgundy, France, known for producing pure, mineral-driven wines made exclusively from the Chardonnay grape. Its cool climate and Kimmeridgian limestone soils, rich in fossilized seashells, give Chablis its signature crisp acidity and flinty character, often described as “steely” or “chalky.” The region is divided into a quality-based cru system: at the top are the Grand Cru vineyards, located on a single south-facing slope and known for powerful, age-worthy expressions; below that are the Premier Cru sites, which offer excellent quality and depth; followed by village-level Chablis, offering classic, lean style; and finally Petit Chablis, made from vineyards on higher ground with lighter soils, yielding simpler, fruitier wines. This hierarchy reflects differences in sun exposure, slope, and soil, making Chablis one of the most terroir-expressive regions for Chardonnay in the world.
