Proprietor Paolo Panerai is adamant about it. Sangioveto is the correct name and spelling of Tuscany’s main indigenous red variety. Panerai is one of Italy’s most successful entrepreneurs. His publishing empire is vast and encompasses a number of journals running the gamut from Milano Finanza, an Italian version of Barron’s, to Class and other glossy lifestyle magazines. Since the late 1970s, Panerai has owned Castellare, one of the jewels of Chianti Classico.
