Made from Grenache, a traditional Provencal grape variety, this sparkling rosé is vinified according to very strict specifications (determination of the ideal harvest date, low-temperature vinification, specific yeast). The method used, named Charmat, is a method of second fermentation that transforms a still wine into sparkling wine in a vat. This process was invented by Jean Eugène CHARMAT at the University of Montpellier in 1907 and was developed because it allowed producers to increase the quantity produced while preserving a high level of quality. Once fermentation is complete, the sparkling wine is filtered and then transferred to draught tanks where it is kept until bottling. This special manufacturing process allows to preserve the original aromas of the base wines.
