Maison Castarede, based at Pont-de-Bordes near Lavardac (Lot-et-Garonne), claims the distinction of being the oldest armagnac shipper the house was founded in 1832, predating the formalisation of armagnac as a commercial export category. The family's original business was river trade along the Baïse, and armagnac was the primary cargo. They have maintained continuity of production and cellar stock across the 19th and 20th centuries, including through the phylloxera crisis and both World Wars.

Castarede's range is anchored in vintage armagnac: single-year bottlings from their own cellar reserves, spanning decades of production. Their sourcing spans both Tenareze and Bas-Armagnac. For programmes seeking historical depth and verifiable vintage provenance in older armagnac with the institutional history to back the claim Castarede's unbroken family record since 1832 is one of the most documentable provenance stories in Gascony.
