The Piaggia farm is situated in the commune of Poggio a Caiano, in the province of Prato, about 14 kilometres west of Florence. It has vineyards in the Carmignano Denomination of Controlled and Guaranteed Origin area, partly in the commune of Poggio a Caiano and partly in the commune of Carmignano.
The winery was set up by Mauro Vannucci, who purchased the land in the DOC area near Piaggia in the mid 70s; he was convinced that the excellent exposure to the sun and the permeable, dry and clayey soil would produce a great Carmignano wine.
He produced the first Piaggia Carmignano Riserva DOCG in 1991 and since then his passion for wine has steadily grown. He has involved his daughter Silvia in this project and she is now the current owner of the winery. At the beginning of the 90s he bought a further 15 hectares in one of the best areas of the appellation, a kind of natural basin a few hundred metres from the centre of Carmignano, which gives a spectacular view of the city of Florence. The current property extends to about 25 hectares, 15 of which are cultivated with vines.
