Domaine Courbis lies at the southernmost tip of the Saint-Joseph appellation, on the right bank of the Rhône, at the confluence with the Isère river, in the communes of Châteaubourg and Glun. This cuvée is sourced from an assemblage of hillside parcels facing south and south-east, overlooking the river at approximately 200 metres elevation. The soils comprise 70% granitic sands and 30% clay-limestone, a rare combination in the appellation that brings both finesse and structure. The vines, averaging 30 years of age, root deeply into these poor soils, naturally limiting yields to around 35 hl/ha and ensuring concentrated fruit character.

Brothers Dominique and Laurent Courbis practise sustainable viticulture in harmony with the environment, with a strong emphasis on manual vineyard work. Harvesting is by hand in small crates, followed by rigorous sorting and complete destemming (100%) to emphasise fruit purity. Fermentation takes place in temperature-controlled stainless steel tanks at 30-32°C, with a twelve- to fifteen-day maceration ensuring maximum extraction of colour and matter. Ageing lasts 14 months: 15 to 20% in stainless steel tanks, 20% in second-use barrels, and 55 to 60% in 2- to 4-year-old barrels. This precise approach brings complexity and roundness without masking terroir and varietal expression.
