BIONAT / BIOSTER commercialise des sauces, moutardes et condiments à travers trois marques engagées dans une alimentation authentique et responsable. Bister, fondée en 1926, incarne le goût belge à travers des produits alliant tradition et innovation locale. La marque s’est distinguée par le lancement de la première moutarde et mayonnaise 100 % bio et belges, en partenariat avec des agriculteurs locaux. Natura, depuis 1939, valorise la simplicité et la qualité. Partie de la mayonnaise, elle a élargi sa gamme aux vinaigrettes et tartinables, désormais tous 100 % bio depuis 2023. Bioster, née en 2001, est spécialisée dans les produits bio pour les magasins spécialisés. Forte d’un ancrage français, elle relocalise ses cultures de moutarde dans l’Aube et développe des recettes avec des ingrédients 100 % français, en collaboration avec une experte du goût.
