The red grape variety (also Sangiovese Grosso) is a clone or variety of Sangiovese. It was probably selected at the beginning of the 18th century in the Montepulciano area of Tuscany, where it is now found exclusively. The vine is said to be very different from other Sangiovese varieties because of its rich tannin content. However, the long held view of a better quality is no longer considered correct, because in terms of DNA it does not differ at all. Strictly speaking, Prugnolo Gentile is just one of the countless synonyms. The name Prugnolo Gentile is mentioned in the DOC/DOCG regulations for Rosso di Montepulciano, Vino Nobile di Montepulciano and Vin Santo di Montepulciano, among others.
