Domain: Château Castera A military fortress in the 14th century, Château Castéra has undergone many changes and had numerous owners. It currently belongs to the German group Deugros. Under the management of the new owner, major renovation work has been carried out and a new sales policy has been introduced. The château and winery have been completely refurbished. A stock of more than 900 barrels renewed by a third each year and an ultra-modern vat room, combined with traditional techniques has helped to steadily improve quality.
