Their son, Jocelyn, who had left school at 16 to help his parents on the still-mixed farm, decided to resume his studies. He passed his baccalaureate as an independent candidate and then moved to Toulouse to attend the Purpan School of Agricultural Engineering, where he graduated top of his class, earning a diploma in oenology. From the late 1970s onward, he devoted himself exclusively to cultivating vines.
A fervent advocate of terroir-driven wines, he became a member of the appellation's association and actively participated in the 1990 recognition of the Vacqueyras terroirs as a Rhône Valley cru.
With his academic background, rare for the time, Jocelyn sought to constantly improve the quality of his wines, drawing on his experience in the vineyard and winery, as well as his innovative spirit. He developed the plot-by-plot approach to winemaking and created a special cuvée for the best vintages. Always curious, he travelled the world and introduced his wines in Europe and Asia. Under his leadership, Domaine des Amouriers became a benchmark in Vacqueyras.
