Jongieux is one of those sites that we do not forget. Its open landscape of medium mountains offers a bucolic panorama. The vines are established on the scree of the slopes of Charvaz montain. Facing South-West, they benefit from maximum sunshine until the last rays of the setting sun. The iconic Marestel hillside is at the heart of the vineyard. Cradle of the Altesse grape variety, it climbs on the side of the mountain.
