The 73 ha vineyard, located a few kilometers east of Saint-Laurent-Médoc towards Château Beychevelle, is planted on a veritable mosaic of soils of various qualities, composed of clay, limestone and Garonne and Pyrenean gravel. on a limestone subsoil. For the red, the grape varieties consist of Cabernet Sauvignon (40%), Merlot (55%) which works wonders on the limestone hill, but also Cabernet Franc (4%) and Petit Verdot (1%). The white grape varieties are divided between Sauvignon (33%), Sauvignon Gris (29%), Sémillon (33%) and Muscadelle (5%). In anticipation of global warming, Bernard Magrez created in 2013 a private collection of 75 grape varieties, a true plant heritage which makes it possible to identify the grape varieties best suited for the future. But for current grape varieties, the average age of the vines is 30 years and the planting density is 8 to 10,000 vines/ha. The culture is traditional, using the principles of reasoned culture and favoring manual work.At harvest time, a first sorting is carried out in the vineyard, a second, manually on a vibrating table, followed by destemming then densimetric sorting in the cellar. Only the best remains! The harvest is then cooled, then vatted by gravity. Vinification follows in small capacity wooden and cement vats. The punching down is entirely manual, the temperature is controlled and does not exceed 28°C. After maceration for around thirty days, aging in barrels, 30% of which are new, lasts 16 months.
