The company produces, bottles, and distributes wines from major French wine regions including Bordeaux, Alsace, and the Rhône Valley, with brands such as JP Chenet, Calvet, and Baron de Lestac. It remains a privately-held family business with limited public financial transparency, and is a significant supplier of wines sold in Australian retailers.
