Le Ragnaie winery extends over 28 hectares in Montalcino in the Tuscan province of Siena. The land is cultivated with both vines and olive groves, grown according to the guidelines for organic agriculture. The vineyards are divided into three distinct parcels of land throughout Montalcino which allows them to produce three diverse terroirs of Brunello: Le Ragnaie, Petroso, and Castelnuovo dell'Abate.

Riccardo and Jennifer Campinoti purchased the Le Ragnaie property with a mix of old vines and younger plantings. The estate spreads across 42 acres, 12 acres of which are in the zone where the cellars are based, Le Ragnaie itself. The vines are the highest of any in Montalcino, some reaching 1,960 feet above sea level, in the south-facing central zone over Soldera di Case Basse. As one of the highest points in the region, it became famous for bird catchers, and in fact the traditional bird catchers' net features on the label as part of the winery's logo. The estate takes its name from the fact that this net looked rather like a spider's web (Ragna, in Italian.)
