Domaine Pascal Cotat is a small family producer in Chavignol, a village within the Sancerre appellation in the Loire Valley. The domaine focuses exclusively on white wine production, working with the Sauvignon Blanc grape that defines the region.

Chavignol sits on distinctive terroir marked by three soil types: terre blanche (limestone and clay), caillottes (small limestone pebbles), and calcaire (hard limestone). These soil compositions shape the character of Sancerre wines, typically producing mineral, crisp expressions with citrus and herbaceous notes. The Loire Valley's cool climate and continental influences further emphasize freshness and acidity in the finished wines.

The domaine's current range includes La Grande Cote, a Sauvignon Blanc from Chavignol that reflects the specific character of the vineyard site. This wine represents the producer's commitment to expressing the limestone-based terroir of the region through Sauvignon Blanc.

The Loire Valley stretches approximately 1,000 kilometers along France's longest river, from the Atlantic coast inland to the central highlands. This extensive wine region encompasses diverse terroirs across four main sub-regions: Muscadet near the Atlantic, Anjou-Saumur in the west, Touraine in the center, and the Upper Loire including Sancerre and Pouilly-Fumé in the east. The Loire ranks among France's most significant wine regions by volume, producing around 4 million hectoliters annually across more than 70 appellations.

The region's continental climate gradually transitions to maritime influence near the coast, with the Loire River providing crucial temperature moderation. Soils vary dramatically from the schist and granite of Muscadet to the limestone and clay of Sancerre, with tuffeau limestone prevalent in Touraine and Saumur. Key appellations include Sancerre and Pouilly-Fumé for Sauvignon Blanc, Vouvray and Savennières for Chenin Blanc, and Chinon and Bourgueil for Cabernet Franc-based reds.

Sauvignon Blanc dominates the eastern Loire, producing mineral-driven wines in Sancerre and Pouilly-Fumé that express their limestone and flint soils. Chenin Blanc creates the region's most versatile wines, from bone-dry Savennières to sweet Coteaux du Layon and sparkling Vouvray. Cabernet Franc achieves particular distinction here, crafting elegant reds in Chinon and Saumur-Champigny with characteristic herbaceous notes and bright acidity. The Loire's cool climate preserves natural acidity across all styles, creating wines known for their freshness, food-friendliness, and ability to express specific terroir characteristics.

Sancerre is an appellation d'origine contrôlée located in the eastern Loire Valley of France, centered around the hilltop town of Sancerre in the Cher department. The appellation was established in 1936 and encompasses 14 communes across approximately 2,800 hectares of vineyards. The region sits on the left bank of the Loire River, about 200 kilometers southeast of Paris.

The Sancerre appellation is built on three distinct soil types: terres blanches (white marl and limestone), caillottes (limestone-rich soils with small stones), and silex (flint-based soils). Only two grape varieties are permitted: Sauvignon Blanc for white wines and Pinot Noir for red and rosé wines. The continental climate features warm summers and cold winters, with the Loire River providing a moderating influence. White wines dominate production, representing roughly 85% of total output.

Sancerre Sauvignon Blanc typically displays mineral-driven characteristics with citrus and herbaceous notes, often showing a distinctive flinty quality attributed to the silex soils. The wines are known for their crisp acidity and ability to express terroir differences between villages and vineyard sites. Sancerre Rouge, made from Pinot Noir, tends to be lighter in style with red fruit flavors and earthy undertones, though production remains limited compared to the white wines.
