On 70 ha in Kochersberg northwest of Strasbourg, the Nonnenmacher family grows asparagus, sugar beet, barley, corn and raises ducks. It is a member of the association of foie gras producers in Alsace (Gänzeliesel) and therefore meets precise specifications: the ducks arrive here at the age of one day and are fed on cereals produced on site for thirteen weeks. Then, the feeding is done twice a day, for twelve days. Slaughtering and processing are then carried out in the farm's laboratory and the products are made from traditional recipes. Among the flagship products are raw foie gras, tunnel foie gras (under golden tin paper: 133 €/kg), semi-preserved Le Parfait, canned foie gras and lobes of foie poached with Guérande salt and black pepper (98 €/kg).
