The estate vineyard is located in the AOP Collioure, where the steep, sloped terroir is planted on terraces to enable cultivation. The climate is dry and very hot during the summer, which naturally reduces the risk of disease and the mitigating sea winds bring minerality and elegance to the wines. The grapes used to produce Tremadoc benefit from the cool, sea breezes all year round. The vines are trained on stakes, which allows for larger canopies to offer the fruit shade from the hot sun. The vines are planted at a high density, which encourages the vines grow deep roots to reach the limited water supplies. Three hectares of plots are weeded by hand. The schist soil is made up of shale which favours a continuous diffusion of heat to the vines and imparts mineral characteristics, elegance and opulence to the wine. The vines are hand-harvested at optimal maturity.
