Domaine Georges Vernay, based at Condrieu in the northern Rhone, is credited with rescuing both the Condrieu appellation and its Viognier grape from near-extinction in the mid-twentieth century. Coteau de Vernon is the estate's flagship Condrieu, drawn from around four hectares on two mid-slope parcels - one planted in the 1960s, the other before 1940, partly by Christine Vernay's grandfather before the appellation existed. The steep, terraced slopes carry the decomposed-granite (arzelle) soils typical of Condrieu, and the estate is farmed organically. The 2021 season in the northern Rhone was cool and challenging, marked by spring frost and reduced yields, producing a fresher, more tightly wound style than warmer recent vintages.

Hand-harvested fruit from the old Vernon parcels is whole-bunch pressed and fermented, with the wine raised in a combination of foudres and barriques, only around 5% of them new, for roughly twelve months. This restrained approach to oak preserves the variety's white-fleshed stone fruit, ginger and floral character while lending a gently creamy mid-palate. Extended elevage on fine lees builds texture and the wine's notable saline length without masking freshness. Malolactic fermentation and low intervention allow the granite terroir to show through in a balanced, mineral-driven Condrieu of real tension.
