Rosario Sireci purchased the Feudo Montoni estate in the late 1800s upon discovering a wealth of ancient vines and passed down the property and closely held secret knowledge to his son and grandson. Our wines are manipulated as little as possible by human intervention, says Fabio Sireci of his familys methods, which employ the cru concept of bottling a wine from the best grapes in a single vineyard. Feudo Montonis pre-phylloxera vineyard, for example, is planted with native Nero dAvola clones.
