The Castelvecchio vineyards stretch over 15 acres (6 hectares) with a vine density of 2207 vines per acre (5434 vines per hectare). They are cultivated using the Guyot method with low yield. The red grape varieties grown are Sangiovese, Colorino, Cabernet Sauvignon and Cabernet Franc, and the white grapes are Trebbiano, Malvasia and Colombana. All the grapes are harvested by hand. Although the vineyards extend contiguously, there is significant diversity within them in altitude, exposition, soil composition and microclimate. For this reason, each single variety and portion of the vineyard is handled separately in the wine making process. Having deep knowledge of the characteristics of each grape as they grow in the particular parts of the vineyard and taking note of their evolution allows us to adapt our choices from season to season to be able to constantly improve the quality of the wines. The winery itself is a simple building, traditionally Tuscan in its dimensions, materials and detailing. It was constructed entirely by the labor of the family members. Our wine making is done under temperature control, and the wine is aged in wood. Particular attention and care is devoted to the selection of the grapes to be laid out to dry on traditional cane mats for the production of the traditional Vin Santo.
