Sauvignon Blanc

Overview

Sauvignon Blanc is the defining white grape of the eastern Loire Valley (Sancerre, Pouilly-Fumé) and the Bordeaux white appellations (Graves, Pessac-Léognan). In the Loire, it reaches its most mineral, terroir-transparent expression: fresh-cut grass, gooseberry, lime, citrus, and (in the best Chavignol sites) an array of distinctive botanicals over a chalky Kimmeridgian limestone foundation. New World Sauvignon Blanc (Marlborough, California) is a stylistically different category — tropical, herbaceous, less structured.

Key Regions

• Sancerre — benchmark; Chavignol sub-village (Cotat, Vatan); Monts Damnés, la Grande Côte, Culs de Beaujeu; can age 20–40+ years at the top estates
• Pouilly-Fumé — across the river from Sancerre; flinty soils add a smoky, “gun flint” character; Dagueneau, Ladoucette

Style Notes

Loire Sauvignon Blanc is distinguished from New World by restrained alcohol (12–13.5%), high natural acidity, mineral transparency, and lack of overt tropical or herbaceous over-expression. The old school Chavignol style (barrel fermentation, low yields, late harvest) adds complexity, texture, and extraordinary longevity — wines from François Cotat and Edmond Vatan can age as long as great white Burgundy. The modern mass-market Sancerre is stainless steel and early-drinking; there is a wide quality gap.

Chavignol Botanicals

A distinctive aromatic marker of great Sancerre: a complex herbal/floral register unique to the Kimmeridgian limestone of Chavignol. Present in the wines of both Cotat cousins and Edmond Vatan.

Synonyms
