The DEAU family history is rooted in the land and its vines, intertwined with the history of cognac itself. Double distillation was invented in the 17th century, giving cognac its unique and excellent qualities. The name of the winemaker Louis Deau appears in the archives during this same period, born in Saintonge in 1665. From generation to generation, the descendants of Louis Deau have cultivated the vines with passion, making the best wines used to create great cognacs. Vintage Cognacs, also known as Millésime Cognacs, are made with eau-de-vie from a single year. This is rather uncommon, since cognac is usually made from a blend of several different vintages from different years. This blending is what creates a signature identity for a cognac company. In 1989, the BNIC (National Interprofessional Cognac Bureau) authorized the sale of very rare Vintage Cognacs provided that their exact age can be proven. Each barrel must be sealed and documented.
