The Guasch family have been in Gascony since the 12th century.
They have owned the château at Bordeneuve since 1974. They are one of the region’s largest courtier and negociant operations. Today, the father-and-son team of Jean-Claude and Thomas look after viticulture, vinification and distillation. There is one short column still at the domaine (almost 100 years old), which produces up to 50–60 casks of new spirit annually. The wine is distilled on its lees, and drawn off at 55–58 %, depending on the harvest. Distillation is continuous through day and night and manually controlled to account for temperature and humidity changes.
