Fattoria Ambra has belonged to the Romei Rigoli family since 1870. The estate located near the Ombrone river and the Villa Medicea of Poggio a Caiano, is named after the poem "Ambra", written in the 15th century by Lorenzo Il Magnifico. The vineyards, of an extension of 18 hectares, stand in the hills of Montalbiolo, Elzana, Santa Cristina in Pilli and Montefortini, four of the most important crus of Carmignano.

In Italy the name of Carmignano has been synonymous of fine wine ever since the 13th century and so great was its reputation that Cosimo III de' Medici, Grand Duke of Tuscany, decreed in 1716 that the appellation be stictly controlled. The borders of the ancient appellation remain identical to this day, making it one of the smallest DOCG areas in Italy.
