The Guicciardini, one of the oldest Florentine families, had a prominent position in the political, social and economic life of Florence since 1200. Their history is inextricably linked to that of the Castello di Poppiano, a medieval building erected around the year 1000 as a fortress to defend Florence from the outside. An act of inheritance from 1199 confirms that it has belonged to the Guicciardini family for at least nine centuries. Today, the castle is one of the most important realities of the 'Chianti Colli Fiorentini' DOCG. The good soils, locally called 'alberese', clayey but rich in skeleton and well drained, are the precondition for obtaining fine wines. The vinification cellar is adjacent to the castle, while the maturation cellar, in oak barrels and barriques, is located in the basement, where the optimum temperature is maintained naturally. Since 2015, Castello di Poppiano has also been joined by another estate, Belvedere-Campòli, in Chianti Classico. Then there is Massi di Mandorlaia, located in Maremma, in this case within the MoreIlino di Scansano appellation.
