2025 · Château Rollan de By

Château Rollan de By is a northern Médoc estate acquired and developed by Jean Guyon, who remains its driving force. Purchased in 1989 as a small property, it became the foundation of the Domaines Rollan de By – Jean Guyon group through the acquisition of additional châteaux. The group is now associated with a substantial vineyard holding, while the available information does not specify farming practices, sustainability certifications, annual production, or a named winemaker.
