Gancia has now again returned to Sicily where it once owned an estate for the production of quality wines and where , coincidentally , the well known Church of Saint Mary of the Angels in Palermo , historically famous for being involved in the Siege of Italy during the Unification of Italy Campaign is also known as the « Chiesa della Gancia ». Gancia has once more deepened its roots further into the warm, fertile soil of this island. The Gancia return to Sicily is linked with the firm intention of producing prestigeous wines also in this land , in those areas best suited to the cultivation of indigenous and international vines .
