Choosing your wine

Sancerre is one of the rare appellations in the world where a single grape variety—Sauvignon Blanc—produces such radically different wines depending on the parcel. The reason lies in one word: the soil. Three main families of terroirs share our hillsides, and each leaves its signature.

This guide details the geology and style of each of Sancerre's three terroirs—Les Caillottes, Les Terres Blanches, and Le Silex—to help you understand what's truly in your glass.

Caillottes are soils of fragmented clay and limestone, often close to the surface, which drain quickly and rapidly warm the vines in spring.

• Style: fresh, round, citrusy, immediately accessible
• Wines that express themselves young, without the need for long aging
• Cuvées: Sancerre white "Grande Réserve" and "Les Côtes aux Valets" (single-parcel)

It's often the first entry point into Sancerre Sauvignon Blanc — a generous style that pleases everyone

In Sancerre, "Terres Blanches" refers to the Kimmeridgian marl – the same geological formation as in Chablis, rich in marine fossils and over 150 million years old.

• Style: taut, mineral, saline, structured, great aging potential
• Cuvées: "La Côte des Monts Damnés", "Jadis", and "Le Cotelin" (single-vineyard)

These are often our most sought-after wines by connoisseurs – those who seek tension rather than immediacy.

Flint forms layers of pebbles and siliceous nodules on a clay base, mainly to the east of the appellation. It is a poor soil, which forces the vine to root deeply.

• Style: Straightforward, intense, with saline and iodine notes, smoky, remarkably long finish
• Cuvées: "ES-56", "d'Antan", and "Les Ruchons" (single plot)

This is the most spectacular terroir in blind tastings — recognizable by its flinty, almost smoky note

Few appellations as compact (less than 3,000 hectares) bring together such geological diversity. This explains why two Sancerre whites can have such different profiles, while sharing the same grape variety and often the same winemaker.

This mosaic of soils, gathered within a few kilometers of Sancerre, is among the most studied in the entire Loire by both geologists and winemakers — a true observation ground for anyone who wants to understand the link between soil and wine style.

Approximately 100 to 150 million years ago, the Sancerre region was covered by a shallow sea. As it receded, it left successive marine deposits—limestone, marl, then flint—which today form the three main soil families of the appellation. Understanding this history means understanding why the wine changes character from one plot to another.

Understanding a terroir is not enough: it also needs to be respected in the vineyard and the cellar. We vinify each plot separately, using methods adapted to what the soil provides — not to erase its differences, but to reveal them. It is this plot-by-plot approach, more demanding than systematic blending, that allows cuvées like "Le Cotelin" or "Les Ruchons" to exist as such.

This also explains why, for an equivalent surface area, Sancerre can offer a range of styles that no other Sauvignon Blanc appellation in the world can claim with the same geological legitimacy.
