The estate has 8 hectares of specialized vineyards which are made up of various grapes and clones such as Sangiovese, Merlot, Cabernet Sauvignon, Syrah, Foglia Tonda, Colorino, Chardonnay and Trebbiano. The grapes are harvested and prepared for the wine making process in the enchanting and antique cellar situated on the Estate to later become the DOC ORCIA and IGT blends. There are also over 500 century-old olive trees growing on the property besides the 2 hectare specialized olive grove which contains approximately 1,000 trees of the Leccino, Frantoio, Maurino and Pendolino varieties. The 100% biological methods used produce the Estate's Extra Vergin Olive Oil D.O.P. named 'Terre di Siena' Castelnuovo Tancredi.
The climate is typically Mediterranean, tendentially dry, but also with continental connotations given the intermediate position between the sea and the Central Apennines. Precipitation is concentrated in the spring and late autumn months (average annual 700 mm.). In winter, snowfall above 400 meters is possible.
