Eric Louis combines traditional Sancerre know-how with a modern, highly controlled cellar. Grapes are harvested at night or early in the morning to preserve freshness, then gently pressed and fermented in temperature-controlled vessels. The estate tracks juice by parcel, uses bioprotection to limit sulphites during fermentation, and protects wines under nitrogen through aging and bottling. Red wines may be raised in selected oak from Tronçais and Bertranges, while the exceptional white Sancerre Cuvée Pauline follows an ancestral approach with fermentation and aging in acacia and oak.
