Average yield per hectare
7,200 kilograms of grapes, equivalent to 4,250 litres of wine (must-to-fruit ratio 59%).
Cuvée Prestige Rosé is obtained from the separate fermentation of Pinot Nero and Chardonnay grapes. The Pinot Nero grapes are transported over the vat where the berries are separated from the stems and fall in by force of gravity. Maceration with brief skin contact lasts 24-36 hours, just enough to obtain the special delicate pink hue that makes Francicorta Rosé such a distinctive wine in the bottle. Later, the must is separated from the skins to be fermented in small oak casks and steel tanks at controlled temperatures. The Chardonnay grapes are vinified in the traditional manner, with whole-bunch pressing. The best fractions of the must ferment separately in vats. After eight months of maturation, the magic ritual of blending the cuvée from the Pinot Nero and Chardonnay base wines is carried out. The cuvée is then bottled and aged for an average of 30 months on the lees in underground cellars at a constant temperature of 12 °C. Disgorgement takes place in the absence of oxygen using a unique system designed and patented by Ca’ del Bosco. The procedure avoids oxidative stress or the need for additional sulphites, making Ca’ del Bosco Franciacortas purer, more appealing and longer lived. Finally, every bottle is given an individual marking to ensure its traceability.
