Located in the foreland Savoyard, Jongieux deploys its vineyard along its sunny hills framed by the high majestic mountains of Charvaz. Ideal for the cultivation of vineyards, the village located at 350 meters of altitude denotes with the usual cliché of the mountain villages of high altitude. Along the meanders of the Rhone, the slopes of the vineyards cling to the mountainside on the western side to enjoy a climate favorable to their flourishing. Overlooked by the benevolent Saint-Romain chapel built on the site of the ruins of a Gallo-Roman temple, the 250 hectares of vineyards benefit from a favorable sunshine to flourish in the middle of the truffle oaks and box trees that constellate the Marestel hillside.
