The Clos Signadore is located in Poggio d’Oletta, within the inland mountainous part of the Patrimonio AOC. The Clos is planted with 40 year old Nielucciu vines, the local red grape of Corsica, closely related to Sangiovese. In addition, there is also a small amount of Vermentinu for the white wines. The vines are divided among four distinct terroirs, which blend together to make a sum greater than the parts. Since the domaine was created, they have avoided the use of chemicals in the vineyards. They only use mechanical weeding, and no chemical products are sprayed on the soil. Since 2010, the domaine is in conversion to the organic AB certification.
Christopher Ferrandis was born in Marseilles to a family with strong roots in Corsica. After working for several years at Domaine Pibarnon in Bandol, he moved to Corsica where he worked as a consultant for a cooperative. Through connections of his uncle who grew up in Corsica, he was able to find a few hectares of old vines that were available, and established the domaine in 2001. In addition to the flagship bottling Clos Signadore, the domaine also produces the cuvée A Mandria in red, white, and rosé.
