Established in 1994, Carmignanp is one of the most recent D.O.C. appellations in Tuscany. It belongs to those appellations that are called "a cascata", or cascade style, where from a single grape variety it is possible to obtain a number of different wines.
It is interesting to note that a D.O.C.G. wine, Chianti Montalbano, is also produced in this same area. The hills of Carmignano comprise Barco Reale, a vast territory that was once a hunting reserve. Today, Barco Reale is the name of a fine wine produced with Carmignano grapes. Very fine Vin Santo and rosé wines, once known here as Vin Ruspo, also have a place in the local winemaking tradition.
These wines are produced in an area that covers the municipal territories of Carmignano and Poggio a Caiano, at an altitude of no more than 133 feet. The terrain here is marly, schistose and clayey.
