Casato Prime Donne is situated 200 metres above sea level and is surrounded by 18 hectares of vineyard. On the ground floor of the stone farmhouse is the ageing winery with oak barriques, tonneaux and larger barrels. This is where the Brunello ages, at first in smaller and then ever-larger containers until reaching the 40hl barrels. The vinification area is divided into two parts. The traditional portion is under a wooden beamed roof, while the more technological and modern area is housed under an iron roof and is open on three sides. It is called “Tinaia del Vento” and has been created so as to make nature the protagonist of quality products. Here the clean air of the Val d’Orcia is used as a fundamental element for the quality of the future wines. The trunk-cone stainless-steel vats are temperature-controlled and here the pumping overs occur automatically without the use of a pump. The rapport with the surrounding countryside is emphasized by the use of selected native yeastschosen at Casato Prime Donne during the 2006 harvest by the Oliver Ogar company. Modern techniques for fermentation which however recall those practiced by our grandfathers.
