The grape variety on which Fattoria del Cerro’s entire production revolves is Prugnolo Gentile, a local Sangiovese biotype. Fattoria del Cerro has conducted a clonal selection process for this variety, representing one of the winery’s most significant contributions to the region. The best plants were identified in the oldest vineyards, and the material was collected and evaluated for yield, oenology, and phytosanitary properties in mother plants. This process resulted in three certified clones—Grifo, Bravìo, and Brescello—with names inspired by the history of Montepulciano.
Alongside Prugnolo Gentile, the estate preserves a heritage of minor native grape varieties: Colorino, Mammolo, Canaiolo, Ciliegiolo, Pugnitello, and Fogliatonda. These varieties had been progressively abandoned due to their lower yields but have proven essential for achieving the complexity of the blends.
Since 2025, the Consorzio del Vino Nobile di Montepulciano has introduced 12 new Additional Geographical Units (in Italian UGA), known as “Pievi”. The subzones correspond to the boundaries of the ancient parishes into which the Montepulciano territory has been divided since the late Roman era and were defined by cross-referencing the 19th-century Leopoldine land registry with recent geological, pedological, and production studies. Fattoria del Cerro is in the Pieve di Sant’Ilario, whose vineyards—including those of Fontelellera—produce a Nobile with a solid tannic structure and pronounced minerality.
