The Domaine de la Roche Bleue is a 6.4 hectares-wide winery located in Marçon, in the northern center of the Loire Valley. Over the Jasnières and Coteaux du Loir appellation areas are grown Chenin Blanc, Pinot d'Aunis and Gamay varietals.
Sébastien Cornille comes from a family of potters in Sancerre. As a child, it is in this region that he developed his passion for the vine. After studying agronomy in the city of Tour, he worked in a wine estate in Chavignol before heading to Réunion Island where he lived eight years as an expatriate. He undertook the bold task of establishing a vineyard of Chenin blanc on volcanic soil amounting to 1000 feets above the sea level. Heavy rain during the summer and the fall made the experience more difficult than expected, which led to his return to France. In 2007 he settled in the Sarthe vineyard to start the Domaine de la Roche Bleue.
Cornille is renown as an innovative and meticulous vinegrower who contributes to the nobility of the wines of Jasnières. He aims for yields of 30 to 35 hectoliters per hectar, the objective is to obtain highly concentrated grapes without losing the unique elegant aromas. Cornille works with the natural yeasts and without the use of synthetic agricultural and winemaking products. Since 2010, all of his vineyard is farmed organically, to be completly certified by Ecocert in 2014.
