Stéphane Robert and his wife Sandrine established their property in 1994. It takes its name from the stone tunnel running beneath the land. The 9-hectare vineyard spans three appellations: Saint Péray, Saint Joseph and Cornas. Stéphane has made a name for himself in the region, and makes wines that are ideal for ageing. The couple practices sustainable viticulture, working all their land manually or with a horse where the terrain permits this. The steepest plots are ploughed with the help of a winch. The grapes are harvested by hand and sorted in situ.
