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.

This Syrah single variety comes from fifty-year-old vines grown on coarse-grained, granite soils. Natacha Chave's ecological choices affect the quantity of yields. These are therefore moderate. Harvesting is done manually and the grapes are sorted directly in the vineyard. She ages her wines for 24 months in demi-muid barrels and pièces. Tasted between 16 and 18°C, this dark, ruby ​​wine offers an intense expression of mocha, cocoa, flowers and black fruit. Natacha Chave has created a full-bodied, dense and deliciously silky wine.
