Already owned by the Marquises Matteucci, the company was purchased in 1979 by the Zonin family that has made the transformation from its mainly cereal–olive original stance, into the current wine–olive orientation.
Fattoria Il Palagio, now owned by Gaetano Zonin, overlooks a typical Tuscan hill in Castel San Gimignano, in the Val Elsa of the Siena area, Municipality of Colle di Val Elsa and for a small part Municipality of San Gimignano, in the heart of a land, the central Tuscany, which has deeply marked the history of Italian art and civilization.
At an altitude of 350 meters above sea level, it has an extension of about 350 hectares, of which nearly 100 are planted with vines and 15 with olive trees.
The soil, consisting predominantly of clays and yellow sands, of good structure, has a good capacity of water retention, that can be appreciated especially in summer, when the weather is dry.
Vineyards are modern, trained with Sylvoz spurred cordon method.
In addition to Chianti DOCG, Vernaccia Di Sangimignano DOCG, particular attention should be paid to Arnolfo Di Cambio, a 100% Sangiovese red wine that ages for 18 months in the barrel cellar of the company and to Sauvignon IGT, defined by Maroni as an "educational" Sauvignon, that has received several times the Diploma of Great Mention at the Vinitaly Wine Exhibition and other awards.
