Ca Rosario is the wine with the greatest structure in the Cos a Cos range. A 100% Monastrell single-varietal from the plot 'La Viña de Rosariet', at 400 metres altitude on the shaded side of the Serra del Torrater, Ontinyent. Trellised vines 20–30 years old, strictly dry-farmed, on calcareous-clay soil. Hand harvest, spontaneous fermentation with native yeasts, 6-day maceration and traditional manual wooden press. Aged in stainless-steel tank, without oak, so that the Monastrell arrives clean with all its fruit and the nerve of altitude. No additives, no added sulphites, unfined and unfiltered.
