Thierry Pillot, Saint Aubin 1er Cru "Les Castets", 2023

Saint-Aubin remains Burgundy's best-kept secret, and Les Castets reveals why. At 300-350 meters elevation, cooler than most Côte de Beaune vineyards and 75% classified as Premier Cru, this appellation captures mountain freshness that warmer vintages crave. Les Castets itself—a clay-limestone plot barely 30 ares, southeast-facing—produces Chardonnay of crystalline limestone character that Thierry Pillot's philosophy of minimal intervention amplifies into pure expression. The steep slope's excellent east-south-east exposure means sun-ripened fruit balanced by alpine cool, white flowers and subtle salt minerality emerging with remarkable definition. The 2023 vintage emphasizes this altitude advantage: aromatic finesse, precise acidity, and mineral purity that suggest elegant aging potential while remaining impossibly fresh now. This wine demonstrates Pillot's mastery across the Côte—different altitudes, different sites, always the same commitment to letting terroir speak.
